The circulatory system is important in circulating blood, nutrients, oxygen and chemicals to the body. A circulatory system commonly consists of the fluid it contains, such as blood, a pumping vessel such as a heart, and the vessels, which carry the fluid through the body. In a closed circulatory system, the fluid, blood, is contained within the vessels as it circulates through the body. The Lumbriculus variegates, or blackworm, is commonly found in stagnant water along the edges of marshes and ponds. Blackworms have a closed circulatory system, which in the blackworm includes a large dorsal blood vessel [1]. Glucose is the most common carbohydrate and is classified as a monosaccharide and is a reducing sugar. Glucose is called blood sugar as well because it circulates in the blood. When blood glucose is high, the pancreas releases insulin, which then helps to transport glucose into muscle or liver cells. There, it's used for energy. If there's more glucose present than needed, insulin helps the glucose to be stored in adipose tissues as fat for potential future energy needs. One immediate effect of the breakdown and conversion of glucose into cellular energy is an increased metabolism, which can manifest itself in the form of increased heart rate, high blood pressure or some other form of arousal such as heightened mental alertness [4].…

In this experiment, the preferences of mealworms towards lighted and dark environments were tested. The main question posed was whether the behavior of the mealworms would be affected by the variable of light, and whether they would move towards or away from the light source (taxis). We placed ten mealworms into two adjoining containers and tried to simulate the effects of above ground and underground by exposing the mealworms to minimal amounts of light in one of the containers (underground), and placing the other container under a lamp (above ground). A beaker of water was utilized as a heat sink to prevent the variable of heat from tampering with the variable being tested. Twenty five-minute interval trials were conducted in total.…

Niebuhr sees it as an obstacle while Friedan sees it as the only way to truly gain freedom. Friedan says “She [women] must learn to compete then, not as a woman, but as a human being. Not until a great many women move out of the fringes into the mainstream will society itself provide the arrangement for their new life plan.” (297) This rejection of tradition, upholding of individualism, and rejection of an idealistic “mystique” perfectly encapsulates many of the values of the enlightenment and is what Friedan upholds as the only way for women to be free.…
1st Essay Since the beginning of history, women have been commended on their natural ability to nurture and their ability to not only nurture children, but everything they take interest in. Unfortunately their interests have always been limited. They are denied the right to be fascinated by anything that doesn’t align with the traditional roles of a woman and that is to: cook, clean, submit to her husband, bear children, and look “pretty”.…
My life is pre-determined by my race and gender. I have felt the pressure to conform to society’s image of a white wealthy male. Being male has given me benefits that many transsexuals have noticed and worked to become accustomed to. In Deborah Rudacille’s piece “Introduction”, Rudacille noted that one person “simply cannot understand why a successful middle-aged man would surrender his cultural power to assume the lower-caste status of a middle-aged woman” (Rudacille XIX). Growing up male already gives me a title and path to what I must become. Early on I was lead to believe I must become the main provider and source of security in my family, and the amount of free will I possess allows me to choose this path for myself.…
Pinworms are the most common type of worm infection, estimating that 10% of the population in the Untied States is infected and 30% of children worldwide. Pinworms are usually easily treated but the infection itself is very easily spread, making it persistent. This small…
Throughout the ages women have been confined to the role of a family wife. Being born a women already gave you a set job to do for the rest of a girl's life.

Thus, in an attempt to further promote equal opportunity between men and women, a second wave of feminism emerged between 1968 and the 1980’s, which can be best characterized by women’s refusal to acclimate to society’s rigid belief of what an ideal woman should be or act like (Mancia, Class, 12/2). This problem is perfectly illustrated in the Feminine Mystique, written by Betty Friedan, in which Friedan discussed the unhappiness of many young women in the 1950’s and early 1960’s despite many of them being married and having children, living the life a woman is “supposed” to have. Furthermore, Friedan complained of young women who were being taught that “truly feminine women do not want careers, higher education, political rights” (Friedan, p. 271). Instead, they were being taught that it was a woman’s “job” to essentially be a housewife (i.e. stay home, clean the house, make food for her family, take care of the kids, etc...) (Friedan, p. 273). However, Friedan largely opposed this view and believed that it embodied the false prototypical stereotype about women. Rather, Friedan believed that a truly feminine woman would do just the exact opposite and does aim for a career, higher education, and political rights in the same way that a man would (Mancia, Class,…
Two different organisms darwin studied are pigeons and earthworms. He learned that all of the domestic pigeons came from the same domestic bird, but changed after some time. He learned that since the pigeons are so old, it is easier for humans to find the breeds. He learned that since genetic variation is so big, he was able to breed many more. Even though this is artificial selection, this supports Darwin’s Theory of Evolution because the pigeons changed after some of the breeding and that is evolution. Darwin also studied earthworms. While experimenting their behavior, he learned that they would do anything for food. He learned that earthworms are sensitive to sound vibrations, even though they don’t have ears. This supports Darwin’s Theory…
