What is the purpose of using genetic engineering to create edible vaccines?
a. to create vaccines that are capable of lasting years in the body to prevent future infections
b. to diminish negative side effects that may occur from administering vaccines with syringes
c. to enhance the flavor of vaccines so people are more likely to use them
d. to prevent widespread diseases in developing countries without using syringes

The answer is D. Vaccines are commonly administered intravenously through the use of syringes. However, studies have shown that there are challenges posed in developing countries that are related to this mode of administration of vaccines. One is the storage of syringes and their handling that reduces the sterility of the needles. This, therefore, increases the risk of the spread of diseases (such as hepatitis) by accidental parenteral infections through use of the needles during immunization exercises.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

the answer is c. altitude. hope this ! #brainiac
