are humans because of evolution. The portion of DNA that is responsible for the structure of proteins is 99.4% common in humans and chimpanzees. Anthropologists say that we are humans because of evolution. The portion of DNA that is responsible for the structure of proteins is 99.4% common in humans and chimpanzees. The dictionary says that human beings are individuals of the genus Homo‚ or more specifically‚ Homo sapiens. That only answers the anthropological aspect of what makes us human.

ABSTRACT A molecular diffusion experiment was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment‚ acetone was placed in a capillary tube and was allowed to diffuse into non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular

Mr. Reeves Page 1 Cultural Diffusion in the Ancient World Throughout history‚ cultures have mixed all over the world‚ changing beliefs‚ creating new ones‚ and changing the way people look at the world along with their existence. This can be proven from anything from music to food‚ but is especially prevalent in world religion and the way that every culture sees their god‚ or gods‚ and how they think‚ worship‚ and even obey‚ in similar manners. Even though Hebrew conceptions differed from the rest

What Makes Us Human What makes us human? What is it that we are made up of? I know a human has a body made up of two legs‚ two arms‚ two eyes‚ a nose‚ a mouth‚ and two ears‚ but that is not what makes us human. Human beings are made up of feelings‚ the ability to think‚ communication‚ and many other elements. Feelings show the way we feel between each other and is the reason for our survival. The ability to think is so important because just because we can think doesn’t always mean we do think.

I read the article‚ Women Have Not Adapted to Casual Sex‚ Research Shows. The article was about how even though women now have more freedom to have casual sex‚ they don’t seem to enjoy it as much as men do. I think that the information in this article was kind of credible. They used an internet survey to ask 1‚743 men and women who had previously had one night stands about how they had felt about it. I think that they could have added into the survey how old the subjects were and what (if any) minority

Ethical Challenges in Business: A Historical Event worth Examination The movie Erin Brockovich is based on actual events involving corporate business knowingly endangering the health of local residents and the environment. This factual event is a great example of capitalism on steroids with no empathy for who are what is destroyed on their path for wealth. The events that unfold show the degenerative break down of ethical values through the business format of Pacific Gas and Electric. PG&E
