The monarch butterfly, as known as Danaus plexippus, is often called the milkweed butterfly because its larvae eat the milkweed plant. They are also sometimes called "royalty butterflies" because their family name comes from the daughter of Danaus, ruler of Argos. There are many other interesting facts about this butterfly including its anatomy and life cycle, where the butterfly lies on the food chain, the migration from Canada to Mexico, why the butterfly is being threatened, and lastly, what is being done to help the butterfly.
The anatomy of the monarch starts with it coloring. The monarch butterfly is bright orange with a white spots in a black margin around the edges. The veins on the wings are also black. The caterpillar is ringed with yellow, black, and white on each segment and has a pair of black fleshy tubercles at each end (Emmel, 1999). Monarchs smell with their antennae while they taste with their feet (Wexler, 1994). While the male monarchs have scent scales on their wings and "hair pencils" on their abdomens which secrete a scent (Emmel, 1999). The male scent is used during mating. The copulation of a male and female monarch can last from thirty to sixty minutes which is about average for most butterflies (Emmel, 1999).
The life cycle starts as larva or caterpillar. First, the monarch lays the eggs on the milkweed plants. Next, the egg hatch into a caterpillar. The caterpillar then eats the milkweed plants until they are large enough to pupate (Emmel, 1999). Then, the caterpillar attaches a pad of silk to a stem of a milkweed plant so it can hang while it transform into a butterfly. Next, the caterpillar sheds it larval skin to reveal the chrysalis inside (Emmel, 1999). After it shed its skin, the pupa hardens and the chrysalis earns it name by glowing in the sun. As the pupa stage comes to an end, the butterfly can be seen through its pupa shell. The monarch emerges by splitting the pupa along the length of it proboscis (Emmel, 1999). First the legs emerge. Then the fluid fill body pumps its fluid into the veins of the wings while the body shrinks to normal size. Finally, the butterfly hangs from the pupa about two hours while the wings dry (Emmel, 1999).

...enetic engineered corn. It cannot sell the corn to European markets so the engineered corn is not the premium corn on the market. With the help of Alvarez, Mexico will still be the place of the monarchs winter home, and the human race objecting to engineered food, the monarch may still have a fighting chance for survival.
With all these interesting facts about the monarch, the anatomy, life cycle, milkweed plant, migration, the endangerment, and the help of Alvarez, it is a wondering why more people are not doing more to help this national treasure.

In the Time of the Butterflies, by Julia Alvarez, takes place in the Dominican Republic during Trujillo’s control of the country. Dedé and Minerva are two extremely different Mirabal sisters, shown by how they respond to Trujillo taking over their country. Dedé and Minerva are only two of the sisters. There are four in total: Minerva, Dedé, Patria and María Teresa. The four sisters take turns throughout In the Time of the Butterflies telling their stories from the 1940s while living in the Dominican Republic. Manipulating her point of view and attitude, Julia Alvarez uses an impassioned style of writing to portray Minerva’s strong leadership and an explicit style of writing to portray Dedé’s willingness to compromise.
To attract the insect, a mature Venus flytrap will grow a very long stalk so that the insect won’t get accidentally eaten. “At the top of the stalk, white flowers that secrete sweet-smelling chemicals, pollen and seeds that are 1mm long”. Venus flytraps has to be serval years old before it can get enough energy to make flowers and seeds. (http://www.ehow.com/how-does_4911676_venus-flytrap-reproduce.html

Borderline Personality Disorder (BPD) affects about 4% of the general population, and at least 20% of the clinical psychiatric population. (Kernberg and Michels, 2009) In the clinical psychiatric population, about 75% of those with the disorder are women. BPD is also significantly heritable, with 42-68% of the variance associated with genetic factors, similar to that of hypertension. BPD can also develop due to environmental factors such as childhood neglect and/or trauma, insecure attachment, and exposure to marital, family, and psychiatric issues. (Gunderson, 2011)

Borderline Personality Disorder (BPD) is a mental illness characterized by patterns of ongoing instability in moods, behavior, self-image, and functioning. An individual suffering from this disorder may act impulsively and experience unstable relationships (The National Institute of Mental Health, 2016). The term Borderline Personality Disorder stems from the idea that the characteristics of this disorder fall between anxiety and psychosis (Cacioppo & Freberg, 2016). According to the National Alliance on Mental Illness (2017), “1.6% of the adult U.S. population have BPD but it may be as high as 5.9%. Nearly 75% of people diagnosed with BPD are women, but recent research suggests that men may be almost as frequently

Silk can be produced from other insects but moth caterpillars are the main contributor to the textile manufacturing of silk since they create a much smoother and finer fabric (Silk History, n.d.). The cocoons are raised by the farmer and are delivered to the factory, or filature, where the silk is unwound from the cocoons and the threads are collected into coils. When the filature receives the cocoons they must sort them according to color, size, shape, and texture. They then put t...
Girls who are circumcised are more likely to be limited in their adolescent exploration thus forming a type of oppression from normal teenage activities. It is essential for teenagers to discover their own bodies and explore their sexuality in order to form a sense of self, this does not imply that young teenagers should commit sexual acts, exploring simply implies that teenagers should know their body and its functions, young women should know their own bodies including their own genitalia especially when females begin their first menstrual cycle. However, later in a female's young adult life sexual acts should not be the taboo subject that it is. Instead women should embrace their sexual life, “FGM is carried out as a way to control women’s sexuality, which is sometimes said to be insatiable if parts of the genitalia, especially the clitoris, are not removed. It is thought to ensure virginity before marriage and fidelity afterward, and to increase male sexual pleasure.” (UNFPA), female circumcision is used in order to deprive women from their sexuality. Female circumcision is no more than a way to control woman, because of this teenagers who have undergone female circumcision are being forced to submit to religious believes that they themselves may not agree with, “The controversial tradition of FGC sets these immigrants apart from the mainstream culture and may complicate their efforts to adjust to life in the United States and cause intergenerational conflict in some families. For instance, parents may consider it important for their daughters to be cut, regardless of the girls’ wishes, as a way to maintain their identity with the family and its cultural community of origin.” (Akinsulure-Smith 358). The effect of being a circumcised female in adolescence in the Unites States is greater than
Pesticides are part of agriculture business. These chemicals are used wide scale, and the expectant mother may actually be able to decrease the cognitive abilities of her child while still in the womb. When foods aren't washed correctly, some pesticides are consumed and can cause mental illnesses. This could affect the ability to learn and succeed in school. Behavioral problems may be developed because of the ingestion of chemicals. During their development, kids can develop a variety of illnesses which affect their ability to socialize and fit in with their peers. In addition, Problems communicating with their classmates can be a huge problem which can lead to poor academic scores. Lastly, pesticides can result in the death of their unborn child because poisoning can occur when too much of these pesticides are accidentally ingested during pregnancy. This is a huge problem, as the death of children born or unborn is a very sad thing for a parent or expecting parent.
Agriculture is the most fundamental resource of society. Without it, humans could not live, especially in the ways we do now where people reside in cities. This means that those cities could not exist without large scale agriculture to sustain them. Since agriculture is such a necessity, people have developed methods to gain more from their land. One of the many solutions besides machinery they have developed to produce higher crop yields is through the use of pesticides. However, those pesticides which have resulted in high crop yields have come at price, and that is human health itself. This seems rather contradictory. Pesticides were designed to help people and society by increased the success of producing high crop yields, and they still do that, but at the same time, those same pesticides have caused unforeseen health risks, primarily to those have had to handle them. The average person would not consider pesticides as being a cause for depression, or in worst case scenario, suicide, but studies have found significant links. Even though California is just one place in the world, it has large agricultural areas which were, and still are, represented in many scientific studies that have found those unforeseen risks from pesticide use. Since pesticides are poisons, producers and safety activities urge several safety precautions to attempt to reduce the effect on human users. However, these precautions sometimes do not prevent long term damages in the people that live and work in such close proximity, which are the agricultural workers. Since the risk are known, policies have been put into place, but despite that, the use of pesticides remains high. Like many of the anthropological readings from this course, there are also added ...
The history of BPD can be traced back to 1938 when Adolph Stern first described the symptoms of the disorder as neither being psychotic nor psychoneurotic; hence, the term ‘borderline’ was introduced (National Collaborating Centre for Mental Health, 2009, p. 15). Then in 1960, Otto Kernberg coined the term ‘borderline personality organization’ to describe persistent patterns of behavior and functioning consisting of instability, and distressed psychological self-organization (National Collaborating Centre for Mental Health, 2009, p. 15).
When the colony becomes well established, the queen begins to lay some eggs that develop into queens and males. It takes a few years before a colony becomes large enough to send out winged males and young queens to start new colonies. The cycle will now begin all over again. Nests come in all shapes and sizes. One tropical species built a nest that extended forty feet below the surface of the ground.
