“20 Years after Dolly the Sheep Led the Way-Where Is Cloning Now?” by Karen Weintraub talks about the technology advances in cloning and how they can be used today. Weintraub discusses the benefits and dangers to cloning. Weintraub provides quotes from significant people throughout the article‚ in order to shed light on topic within cloning. She also provides information and opinions about each topic. Because of these factors Weintraub appears to be a credible unbiased author‚ that is capable of

ways. For example‚ if testing goat’s milk‚ sheep’s milk‚ skim milk‚ and two percent milk‚ and the results are similar‚ and then the basic structure of the milks DNA is similar. This conclusion can come in use when products are being tested on cows‚ sheep‚ and goats. Also‚ this experiment can be useful in knowing if the bacteria that have a possibility of growing in the milk people drink everyday‚ is safe or harmful. Bacteria are prokaryotic cells. They feed on dead organic matter‚ chemosynthesis‚

Introduction Every cell is selectively permeable to different molecules. This type of selectively is caused by a semi-permeable membrane‚ which allows the movement of certain molecules across it. Water exchange can be measured in two ways: RBC osmotic permeability is measured‚ and diffusional water permeability is measured (Benga and Borza 1995). Diffusion is the movement of high concentration to low concentration. The diffusion of water across a permeable membrane is called osmosis. Water concentration

Explain why you did this exercise. Where there any safety precautions you needed to follow? If so‚ what were they? The safety precautions in this exercise were to wear goggles and gloves due to being exposed to chemicals and dissection of the sheep and cat heart. Appropriate work space was also required.

A cut is completed to separate the kidney in half. There is a thin membrane that covers the kidney. This being the renal capsule. The outer ring‚ the inner section as well as chambers are visible. Both the sheep and the pig kidney have the distinctive kidney bean shape. The cortex of the kidney is striated. The next layer is the the medulla. This area appears quite fatty. The area where the nephron and and renal arteries are located. The white section‚ in

surgeons were ignorant of the human body and surgical procedures were almost never successful. They were continuously trying to unveil the mysteries of the body. How and why it functioned‚ its purposes‚ and its needs. Dissections uncovered the most knowledge of the body. However‚ dissections were rare because they were illegal and very risky. If a surgeon was going to dissect someone he did it at night and in secrecy. Many admirable surgeons attained their knowledge and experience on the battlefield

Areas of Knowledge: Invented‚ Discovered‚ or Both? One cannot say with certainty that specific areas of knowledge are invented nor can one say with certainty that areas of knowledge are discovered. Two areas of knowledge that deal with this topic are mathematics and natural science. In my opinion‚ I believe that mathematics is an invented area of knowledge with some discovery whereas science is a discovered area of knowledge with some invention. Certain topics and categories of mathematics might
