Answer:
The following are the steps for making the human insulin protein for the health care market:
1. Obtain the DNA from a human being who does not have diabetes.
2. Modify the human gene, and provide it a promoter, which will get turn on when placed within the E.coli cell.
3. Separate and make copies of the gene encrypting the insulin protein.
4. Application of electroporation or heat shock method in order to administer the human insulin gene within the living E.coli cell.
5. Development and growth of E.coli in the fermentation culture, and then extract and sell the humulin in the market.
Natural selection. Only spiders that were more resistant to the pesticide lived through the first spraying of the pesticide, thus we're the only ones that could reproduce. This in turn made the offspring of the previous generation more resistant as well; thus making the pesticide less effective.
Answer:
A balance of bodily fluids will prevent the development of diseases, the deterioration of body organs, and death of animals.
Explanation:
Water, blood, saliva, sweat and other body fluids should be kept constant and balanced through homeostasis because the sharp rise and fall of these fluids will prevent the organs of the body from operating optimally and this can lead to the development of diseases and consequent death. For example, water is a vital fluid. Too much of water in the system can lead to diseases like Edema where the legs begins to swell because there is no way of letting out body fluids from the body.
Too little water in the body can lead to dehydration and the increase in blood pressure because of the excessive concentration of solutes. The digestive and urinary systems have mechanisms to keep this fluid under control.
Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).
On the other hand, a Mendelian trait is controlled by a single locus.
