Resisting Stereotypes is unrealistic essays

Resisting Stereotypes is unrealistic essays Look deep in your heart and ask yourself a question: Can you resist stereotyping? The United States consists of immigrants from all countries. All cultures, like people, are different and seeing someone who differs from oneself motivates us to stereotype or label, for example, ones way of talking, dressing, acting, and so on. Though it is impossible to avoid stereotyping, the use of stereotypes may actually be beneficial in some cases. We cannot avoid stereotyping because a human beings mind is created to observe, criticize, and categorize. These tendencies were present in our everyday life and manners from time immemorial. In addition, some stereotypes may take roots from family beliefs and principles. For example, native people in the country may bring up their children to avoid another nation, or immigrants, by teaching them their assumptions and generalizations without any contiguity with the people. This behavior, in my opinion, takes away from their childrens chances to acquire some knowledge and experiences by interacting with other cultures and beliefs. Sometimes stereotypes open our eyes to something we have never realized. They shape how we see ourselves and our values as members of our group, and how we see ourselves as different from members of other groups. For example, Thea Palad in her essay, Fighting Stereotypes, described that she considered herself an American, before her classmate showed her the view of Palad from the view of white American girls. And even though she spent her life in America, she didnt realize that she wasnt like white American girls in school. But it was difficult for me to comprehend how people today could still focus on the shape of my eyes and the texture of my hair, points out the author. For a moment, she lost her identity in society.

Why Veins Look Blue Even Though Blood Is Red

Why Veins Look Blue Even Though Blood Is Red Your blood is always red, even when it is deoxygenated, so why do your veins look blue? They arent actually blue, but there are reasons why veins look that way: Skin absorbs blue light:  Subcutaneous fat only allows blue light to penetrate skin all the way to veins, so this is the color that is reflected back. Less energetic, warmer colors are absorbed by skin before they can travel that far. Blood also absorbs light, so blood vessels appear dark. Arteries have muscular walls, rather than thin walls like veins, but they likely would appear the same color if they were visible through the skin.Deoxygenated blood is dark red:  Most veins carry deoxygenated blood, which is a darker color than oxygenated blood. The deep color of blood makes veins appear dark, too.Different sizes of vessels appear different colors:  If you look closely at your veins, for example, along with the inside of your wrist, youll see your veins are not all the same color. The diameter and thickness of the walls of the veins play a part in the way light is absorbed and how much blood is seen through the vessel.Vein color depends on your perception:  In part, you se e veins as more blue than they really are because your brain compares the color of the blood vessel against the brighter and warmer tone of your skin. What Color Are Veins? So, if veins arent blue, you may be wondering about their true color. If you have ever eaten meat, you already know the answer to this question! Blood vessels appear reddish-brown in color. There isnt much difference in color between arteries and veins. They do present different cross-sections. Arteries are thick-walled and muscular. Veins have thin walls.
