common and well known disease that becomes more and more common every day. The disease is based on sugar is the body‚ or glucose. When your body breaks down carbohydrates‚ it produces glucose‚ and essential sugar for the human body. There is a bodily function in which insulin helps the body use glucose‚ and this process is broken in diabetics. Due to this‚ the amount of sugar in a diabetic is raised to dangerously high levels. The consequences to leaving this untreated include blindness‚ heart disease

used for many reasons. Emulsifiers can help to make a food appealing. The example of the mayonnaise without the emulsifier shows how unappealing it would be if the oil and water separated before it was used. Emulsifiers have a big effect on the structure and texture of many foods. They are used to aid in the processing of foods and also to help maintain quality and freshness. In low fat spreads‚ emulsifiers can help to prevent the growth of moulds which would happen if the oil and fat separated.

Theories of Biology University of Phoenix – Axia There are seven major theories of Biology that attempt to organize and make sense of the multitude of ideas surrounding the major theories of Biology. The theories include evolution of natural selection‚ inheritance‚ cells‚ biological classification‚ bioenergetics‚ homeostasis‚ and ecosystems. The evolution of natural selection is the theory the theory that attempts to explain how and why species are able to adapt to their environments
