Are Gender Roles Defined by Society or by Genetics free essay sample

The article â€Å"Why gender matters: What parents and Teachers need to know about the emerging science of sex differences† is about a book revision of Dr. Sax, in which he talks about that gender differences are created biologically. Although society rules on Gender are overtaking biological factors. He says that it is also important to know how girls and boys are developed and raised. One example to support this is single sex activities. He also points out that there are genetic differences on how men and women think, act react, and feel.Studies also show that boys talk more about drawing verbs such as, â€Å"An alien about to eat somebody. † whereas, girls talk about drawing verbs like plant and trees. Girls develop an early connection between a brain structure called amgdala and the cerebral cortex, which facilitate girls to talk about their feelings more openly. In boys these connections develop later on in life, that’s why they have trouble expressing their emotions. We will write a custom essay sample on Are Gender Roles Defined by Society or by Genetics? or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Basically Dr. Sax is trying to say that parents and teachers should recognize these differences while children are in school and recognize that there are different needs for boys and girls.The common ground of both articles is that although, boys and girls are developed biologically different in some ways but society has played major role in their lives physiologically and psychologically. According to Dr. Fine, gender differences are based on learned behavior. For example she stated â€Å"The more I was treated as a women, the more woman I became. † This means that as soon as the child is born a sort of social conditioning begins. The child whether a boy or a girl will end up being taught many different sets of behaviors and how they should act. She also states that when children are born, there is no such difference in brain.They do not inherit intellectual differences. Basically, children start from a clean slate. Gender differences are learned from culture and society. This is how they learn what roles are expected of them. For example, boys do not develop special skills because of innate differences, it is because they are expected and encouraged to be strong, artistic and smatter in math. Similarly, girls are treated to be more emotional, empathizers and talkative. Dr. Fine does not disagree completely with opposing article; she does imply that there is no enough evidence to support the gender stereotypes.Psychology today blog also supports Dr. Fine’s idea that human behavior is learned from the society and culture. This blog is stating that men learn that they are not good at communicating their emotions. Women, on the other hand, learn that they are bad in math and can’t take leadership roles. Dr. Sax also agrees that â€Å"it is important to chip away at gender stereotypes, we should also recognize variances in how girls and boys develop. † He states that people are so much into society, where boys are given behavior modifying drugs and girls given antidepressant drugs.It is all because boys are taught to be aggressive and girls are taught to be very emotional. He thinks boys and girls act this way because of different brain anatomy in them and based on that, they act, feel, think and develop differently. For example: in risky situations, boys act more likely to be exhilarated by risky situations. Whereas, girls are more cautious and express fear in these type of situations. According to Sax, one of the ways to accommodate the different needs of boys and girls is single sex activities, where boys and girls will choose classes based on interests and abilities rather than gender stereotypes.

The Science Behind Milks White Color

The Science Behind Milk's White Color The short answer is that milk is white because it reflects all wavelengths of visible light. The mixture of reflected colors produces white light. The reason for this is due to the chemical composition of milk and the size of the particles contained within it.   Chemical Composition and Color Milk is about 87% water and 13% solids. It contains several molecules that dont absorb color, including the protein casein, calcium complexes, and fats. Although there are colored compounds in milk, they are not present in a high enough concentration to matter. The light scattering from the particles that make milk a colloid prevent much color absorption. Light scattering also accounts for why snow is white. The ivory or slight yellow color of some milk has two causes. First, the vitamin riboflavin in milk has a greenish yellow color. Second, the cows diet is a factor. A diet high in carotene (the pigment found in carrots and pumpkins) colors milk. Why Skim Milk Is Blue? Fat-free or skim milk has a bluish cast because of the Tyndall effect. There is less of ivory or white color because skim milk doesnt contain the large fat globules that would make it opaque. Casein makes up about 80% of the protein in milk. This protein scatters slightly more blue light than red. Also, carotene is a fat-soluble form of vitamin A that is lost when fat is skimmed, removing a source of yellow color. Summing It Up Milk isnt white because it contains molecules that have a white color, but because its particles scatter other colors so well. White is a special color formed when multiple wavelengths of light blend together.
