The 4 Stages of the Ladybug Life Cycle

The 4 Stages of the Ladybug Life Cycle Ladybugs go by several other names: lady beetles, ladybug beetles, and ladybird beetles. Regardless of what you call them, these beetles belong to the family Coccinellidae. All ladybugs progress through a four-stage life cycle known as complete metamorphosis. Embryonic Stage (Eggs) Wilfried Martin / Getty Images The ladybug life cycle begins with an egg. Once she has mated, the female ladybug lays a cluster of 10 to 50 eggs. Usually, shell deposit her eggs on a plant with suitable prey for her offspring to eat when they hatch; aphids are a favorite food. Between spring and early summer, a single female ladybug may produce up to 1,000 eggs. Scientists believe ladybugs lay both fertile and infertile eggs in the cluster. When aphids are in limited supply, the newly hatched larvae will feed on the infertile eggs. Larval Stage (Larvae) Pavel Sporish / Getty Images In about four days, the ladybug larvae emerge from their eggs. Species and environmental variables (such as temperature) may shorten or lengthen this time frame. Ladybug larvae look somewhat like tiny alligators, with elongate bodies and bumpy exoskeletons. In many species, the ladybug larvae are black with brightly colored spots or bands. In the larval stage, ladybugs feed voraciously. A single larva can consume dozens of aphids per day. Larvae feed on other soft-bodied plant pests as well, including scale insects, adelgids, mites, and insect eggs. Ladybug larvae dont discriminate when feeding, and will sometimes eat ladybug eggs, too. The newly hatched larva is in its first instar (a developmental stage that occurs between molts). It feeds until it grows too big for its cuticle (soft shell), at which time it will molt. After molting, the larva is in the second instar. Ladybug larvae usually molt through four instars, or larval stages, before preparing to pupate. The larva will attach itself to a leaf or other surface when it is ready to pupate (metamorphose into its adult form). Pupal Stage (Pupae) Pavel Sporish / Getty Images In its pupal stage, the ladybug is usually yellow or orange with black markings. The pupa remains still, attached to a leaf, throughout this stage. The ladybugs body undergoes a remarkable transformation, directed by special cells called histoblasts. The histoblasts control a biochemical process through which the larval body is broken down and reformed into the adult ladybug. Depending on the species and environmental variables such as temperature, the pupal stage may last 3 to 12 days. Imaginal Stage (Adult Beetles) Jà ¶rg Mikus / EyeEm / Getty Images Newly emerged adults, or imagos, have soft exoskeletons, making them vulnerable to predators until their cuticles harden. They also appear pale and yellow when they first emerge, but soon develop the deep, bright colors for which ladybugs are known. Adult ladybugs feed on soft-bodied insects, just as their larvae do. Adults overwinter, usually hibernating in aggregations. They mate soon after becoming active again in the spring. How to Find Ladybug Eggs and Larvae If you have a garden plant that is prone to aphid infestations, you have access to prime ladybug habitat. If you want to familiarize yourself with the ladybug life cycle, visit this plant daily. Take your time examining the leaves, lifting them to observe the undersides, and youll likely find a cluster of bright yellow eggs.  Within a few days, tiny ladybug larvae will hatch, and youll find the odd-looking immature ladybugs on the prowl for aphids. Later, youll see dome-shaped pupae, shiny and orange. If aphids are abundant, adult lady beetles will hang around, too.

A View from the Bridge by Cherokee McDonald & Two Ways of Seeing a Essay

A View from the Bridge by Cherokee McDonald & Two Ways of Seeing a River by Mark Twain - Essay Example 2. Comparative Analysis Although the two essays deal with two different subject matters and themes yet there are some similarities in the thematic concerns and symbolism incorporated by the two authors. However the technique or the style of narration utilized and the depiction of the theme and symbols highlight their individualistic writing styles. 2.1. Narration Technique Mark Twain in his treatise uses the technique of third person narration which provides the readers with a chance to draw their personal conclusions as he acts as a mediator between the reader and the text. On the other hand McDonald employs the first person narration technique. Although generally it is assumed that first person narration limits a text’s interpretations for the readers since it is a first hand account of a writer’s explication of a situation. Yet the incorporation of the dialogues can be inferred as a technique employed in order to establish a close connection between the action of tak ing place in the essay and the readers. The use of dialogues also camouflages the presence of the writer or the narrator in the text. However a major similarity that is observed in the depiction of writing style is that both authors illustrate detailed descriptions. As observed that McDonald says, â€Å"He was a lumpy little guy with baggy shorts, and a faded T-shirt and heavy sweat socks falling down over old sneakers† (). Similarly Twain states, â€Å"A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold†¦ in another the surface was broken by boiling, tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles...high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun† (). Hence both the writers pay special attention to t he minute details. 2.2. Thematic Concern A major common theme that both the authors deal with in their respective pieces of work is the theme of innocence although the manner in which they project it is different. It is stated in Two Ways of Seeing a River that, â€Å"Now when I had mastered the language of this water and had come to know every trifling feature that bordered the great river as familiarly as I knew the letters of the alphabet, I had made a valuable acquisition†¦ All the grace, the beauty, the poetry had gone out of the majestic river† (). This line can be interpretted as, that the writer believes it is better to retain an aura of mystery or innocence and all the secrets should not be revealed so that it can stimulate human curiosity and interest. Since when all the mysteries are unveiled as is the case with the river than it becomes monotonous and even stifling because the newness fades away. Moreover in terms of human beings and their behavior it can be perceived that Overanalyzing of people or even ones self can result in the loss of beauty (however bittersweet) of humanity. A similar theme is used by McDonald in his essay. He emphasizes the importance of innocence through the actions of the blind child i.e. since his lack of sight hinders his quest for knowledge the

This research project will highlight the crucial need to respect the diversity of all students, and consideration towards different learning styles. It is hoped that the primary researcher will present herself as a role model for other educational researchers to investigate and implement inclusive teaching practices. The research aims to highlight how EAL pupils learn, and key factors that affect their learning processes. It is acknowledged that when planning a research or teaching project that the diversity of pupil characters be recognised as a resource. Ultimately, this project’s goal is to ascertain best practice methods to enable purposeful learning environments for EAL students and to encourage positive relationships with EAL students. It is hoped this will be achieved through recognition of support needs for bilingual students, and and the need to provide class structure and resources oriented towards individual differences, be these gender, culture, ethnicity or achiev ement. A stimulating and motivating classroom that provides for equal learning opportunities is a key vision of this project.  This study aimed to be the first step in a personal action project, and so has identified areas of EAL student-teacher interaction that require change, or that are opportunities to be encouraged. Action research is considered a family of research methods that are oriented towards action, or change, and research understanding.

Water Quality Of Perlis River Environmental Sciences Essay

Water Quality Of Perlis River Environmental Sciences Essay Malaysia is enriched by abundance of natural resources and one of them is the rivers or also known as surface water. River or surface water is precious and vital natural resource for all life on Earth especially human being as it provides water supply for human domestic use, irrigation for agriculture, as a means of transportation, industries use and so on. Even though there always has been plenty of fresh water in Malaysia, clean water supply has not always been available due to the rising water pollution problem. Nowadays, Malaysia has become an industrialized country and no longer left behind the other developed countries but at the cost of the environment. Effluent from the industrial area which is then discharged directly into the rivers without prior treatment is the main sources of water pollution. Besides, human activities such as the uses of agricultural chemicals, soil erosion due to improper development project, land use and so on are also contributed significantly to water pollution (Niemi et al., 1990). Pollution of river with high concentration of toxic chemicals and excess nutrients, which are resulting from surface water runoff, leaching from landfill site and ground water discharges has been aroused the public concern towards the water pollution issue. Thus, there is a need to assess river or surface water quality due to the increased understanding of the importance of water quality towards public health and aquatic life (Ying, 2005). Peninsular Malaysia consists of 11 states and two federal territories whereas Perlis is the smallest state among them. Perlis state is situated at the northwest of peninsular Malaysia. There are more than ten major rivers within the Perlis area while Perlis River is one of the most important rivers in Perlis. The length of the Perlis River is approximately 11 km through Kangar city to Kuala Perlis while the size of the river basin is approximately 310 kmÂÂ ². Perlis River has become the center stage for the public to socialize and for recreational activities particularly at Denai Larian Sungai Perlis. The number of visitors who are visiting to the river and surrounding area for rest and recreation purpose is estimated to be achieved 10,000 peoples per month. However, the quality of Perlis River does not reach the desired level and it is much difference if compared to the major rivers at developed countries. There are some problems which occurred at Perlis River at present. According to the Interim National Water Quality Standards for Malaysia, the status of water quality at Sungai Perlis is classified as Class III. There is heavy erosion occurred at Perlis River and leading to the river banks become very shallow. Residents which located surrounding the river have thrown rubbish or solid waste into the river therefore causing to unaesthetic scene and it is not accessible to boats. Besides, there is a landfill located in Kuala Perlis and this directly affects the water quality of the river when the leachate is leaching out. Squatters located near the river reserve area are also causing pollution problems and there is a need to regular patrols or hut-to-hut checks. Other point source pollution such as shrimp livestock ponds, Kangar wet market, esplanade at Perlis River, food stalls and the Kuala Perlis fisherman jetty are contributed significantly to the water pollution at Perlis River. (w ww.1s1rcommunity.net) On the other hand, the sources of water pollution can be categorized into point and non-point sources. Point sources of pollution refer to those easily identifiable pollutants which enter the water resource though a direct route, for example, effluent from wastewater treatment plants. Whereas for non-point source pollution, it refer to those pollutants which enter from diffuse sources and they are difficult to control, such as stormwater runoff (P.Jamwal et al., 2008). In this study, Mann-Kendall trend test and principal component analysis (PCA) have been applied to detect the trends of water quality data and to obtain the most significant parameters in order to trace the sources of pollutants. Mann-Kendall trend test is one of the most widely used non-parametric tests to detect significant trends in time series. It has the advantage that their power and significance are not affected by the actual distribution of the data (Hamed, 2009). Therefore it is more suitable for detecting trends in hydrological time series, which are usually skewed and contained the outliers. Mann-Kendall trend test has been widely used in assessing the variability on hydrological time series (Hamed, 2008). The examples of earlier studies which applied Mann-Kendall technique are trend study and assessment of surface water quality in the Ebro River (Bouza-Deano et al., 2008), hydrological trend analysis due to landuse changes at Langat River basin (Juahir et al., 2010), identification of hydrological trends at Canadian Rivers (Khaliq, 2009) and so on. Principal component analysis (PCA), one of the multivariate statistical techniques, is helps in reducing redundant parameters with minimum loss of original information (Helena et al., 2000). A better understanding of water quality can be achieved through the interpretation of complex water quality data matrices. Besides, it allows the identification of possible factors or sources that affect water systems and therefore a reliable management of water resources as well as swift solution to pollution problems can be found out (Vega et al., 1998; Wunderlin et al., 2001; Reghunath et al., 2002; Simeonova et al., 2003; Simeonov et al., 2004). In recent years, principal component analysis (PCA) has been applied in various aspect of field including environmental issues. It has been used to characterize and assess water quality data, and it is efficacious in verifying temporal and spatial variations caused by natural and anthropogenic factors (Helena et al., 2000; Singh et al., 2004, 2005). The examples of application of PCA in environmental issues are interpretation of ground water hydrographs (Winter et al., 2000), examination of spatial and temporal patterns of heavy metal contamination (Shine et al., 1995) identification of herbicide species related to hydrological conditions (Tauler et al., 2000) and so on. The aims of this study are to detect the trends of water quality data at Perlis River and determine the significant parameters that contributed to water pollution by using Mann-Kendall and principal component analysis techniques. A deeper understanding of the evolution in water quality from the year 2003 until year 2007 can be achieved via the Mann-Kendall trend test. Besides, by using the principal component analysis (PCA), the sources of pollutants can be traced and thus some mitigation measures can be carried out.

Discriminatory Practice Essay

Infringement of rights: not respecting an individual’s rights and not letting them practice their culture. This can lead to individuals feeling devalued and very sad, which will affect their health. An example of this say for instance in a care home it was Eid and they was not allowed to celebrate it however all the other occasions were allowed, this would make an individual feel devalued and as if their needs or wants aren’t important, like their culture isn’t important this could lead to health problems as what they enjoy in their culture has been excluded and taken away from them. Covert use of power: hidden use of power to discriminate. This can lead health and social care professionals to treat someone differently from someone else. This means that a person may not get that same level of treatment, which may jeopardise their health and well-being. One example would be when people apply for job. Although one person may have the same experience and qualificati on as the other applicants they may not be shortlisted because of their skin colour, or sexuality etc. it’s harder to prove that covert discrimination is occurring but cases are regularly reported and is still happens. In a health and social care professional setting a health care worker may not give somebody the right medication at the right time, maybe due to the colour of their skin colour or their sexuality which they strongly feel opposed to. Overt use of power: openly using power to discriminate. This will have similar outcomes to covert abuse of power. However, if a person being treated notices that they are being discriminated against, it will have a negative impact on their recovery, their mental health issue to depression and it could make a negative impact on their recovery as they may worry about what they have even done in the first place to be getting this treatment. An example of over abuse of power could be if a health care worker tells a person they are too fat to live their 50s. Another example when a colleague is paid more than you, because of their gender, even though you are doing the same job with the same qualifications. It can also be found in the different treatment one person receives compared with another when there should be no difference at all. Prejudice: is prejudgment, or forming an opinion before becoming aware of the relevant facts of a case. The word is often used to refer to preconceived, cynical ideas about another individual, arising from a per son’s negative ideas about that person, usually unfavourable, judgments toward people or a person  because of gender, political opinion, social class, age, disability, religion, sexuality, race/ethnicity, language, nationality or other personal characteristics. For example, more than 700 people with a diagnosis of schizophrenia in 27 different countries were interviewed as part of International Study of Discrimination and Stigma Outcomes, 72 per cent of those interviewed said they felt the need to conceal their diagnosis. 64 per cent said the anticipation of discrimination stopped them applying for work, training or education programs and 55 per cent said it stopped them looking for a close relationship. In the health and social care sector could be care worker telling another care worker that he or she does not want to work with someone or get them over and done with as they don’t like them due to whatever reason may be. Stereotyping: assumptions made about an individual judged on their group, environment and it may not always be true and sometimes it is based on another persons or groups qualities and life, this is dangerous as it could make the service user feel depressed and mess them up mentally due to the ‘name callingâ⠂¬â„¢. For example, it may be a stereotype that Asian people love to eat rice. So according to this stereotype, if you are Asian, that automatically means that you will unconditionally love to eat rice. This can already show that generalizations made from stereotypes are not the most reliable to base your judgement on. Typically racial and ethnic group stereotypes come from some degree of prejudice thought. In a health and social care area this may occur when a health care worker sees a dark skinned black man and instantly think he is a thug so they chose not to assist them and move them on to someone else. Labelling: Labelling people refers to a form of prejudice and discrimination where a person allocates names to people on the basis of nationality, religion, ethnicity, gender, or some other group. Labelling of people represents a way of differentiating and identifying people. This practice is normally conducted on minority groups. For example, if you label someone who is wearing black as a Goth, you will assume them to be a depressing and dark-minded person, when in fact they might not be at all. This can lead to prejudice and discrimination. Labelling is basically a combination of all the other three things you have listed in your question, and is the ultimate form of ignorance and assumption. In the health and social care profession you need to be aware of this tendency to label people. Labelling thoughts may come into your head  and everyone has these types of thoughts but it’s what you do with them that are important. By becoming aware of your labelling thoughts, you can control them and stop them interfering with your work. Another example in the health and social setting is if a care worker was having a conversation with another care worker and referring a service user as the ‘bimbo’ just because of the colour of their hair such as blond this would be labelling and it would distress the user. Bullying: Bullying is a persistent attempt to hurt or humiliate someone, it is a repeated action and deliberately hurtful. The person bullying is more powerful than the person bullied, making it hard for those being bullied to defend them. Bullying can occur in many different forms. It can be physical (hitting, pushing, and damaging others’ property); it can be verbal (name-calling, threats) or social (excluding someone, spreading rumours). Bullying is not only between children and not only in schools; can it happen at home, in organisations, at work or on the Internet. Bullying is often based on perceived differences, such as ethnicity, sex or disability, so young LGBT people evidently have a higher risk of being bullied. In a health care sector a health care worker may tell a service user that they needs to stop eating as they are already too fat. Abuse: Abuse is the improper usage or treatment of an entity, often to unfairly or improperly gain benefit. Abuse can come in many forms, such as: physical or verbal maltreatment, injury, assault, violation, rape, unjust practices; crimes, or other types of aggression. Abuse of authority, in the form of political corruption, is the use of legislated or otherwise authorized powers by government officials for illegitimate private gain. Misuse of government power for other purposes, such as repression of political opponents and general police brutality, is not considered political corruption. Neither are illegal acts by private persons or corporations not directly involved with the government. An illegal act by an officeholder constitutes political corruption only if the act is directly related to their official duties. Abuse of authority is separated from abu se of power in that the act is originally condoned, but is extended beyond that initially conceived and is in not all cases.

Fetal Alcohol Syndrome ( Fas ) - 1404 Words

Children are born every second of every day on all different parts of the globe. However, before they are introduced into the world they must develop in a special incubator known as the mother’s womb. Throughout the nine months of growth, it is crucial for the mother to consume certain nutrients and avoid harmful substances. In many countries, one of the cognitive disorders is Fetal Alcohol Syndrome (FAS). According to Feldman (2009), Fetal Alcohol Syndrome is a disorder that is induced by pregnant women who have consumed alcohol during the duration of their pregnancy, possibly resulting in mental deformity and delayed the growth of the child. Some characteristics of FAS include growth deficiency and central nervous system dysfunction†¦show more content†¦Impairment of the central nervous system results in an array of behavioral problems including hyperactivity, Attention Deficit Disorder (ADHD) and impaired language, as well as difficulties learning and understandi ng social skills (Thomas, 2008). In addition, prenatal exposure to alcohol disrupts the development of major regions in the central nervous system such as the hippocampus, which contributes to memory (Thomas, 2008). The exposure to alcohol during development in the womb, consequently damaging the central nervous system and the hippocampus, makes the child’s learning experience more difficult due to the fact that their learning and their ability to memorize has been impaired. A research study that was done by Sarah N. Mattson, Katherine E. Calarco and Aimee R. Lang has proven that children that have been exposed to alcohol have a slower reaction time and a lower accuracy to respond correctly to a set of stimuli that was presented. The children were evaluated using a paradigm consisting of three conditions: visual focus, auditory focus, and auditory-visual shift of attention (Mattson, 2006). The result concluded that children with FAS have a deficiency in visually focused att ention and a deformity in maintaining auditory
