Questions: 8 In which process are microbes genetically changed to produce animal proteins? A. adaptation B. variation C. genetic engineering D. selective breeding

The answer is C: genetic engineering.

Explanation for each option:

A. Adaptation: This refers to the process by which organisms adjust to new environments or changes in their current environment. It is a natural process and does not involve intentional genetic changes to produce specific proteins.

B. Variation: This is the natural occurrence of differences among individuals within a species. It is not a process used to intentionally change microbes to produce specific proteins.

C. Genetic engineering: This is the deliberate modification of the characteristics of an organism by manipulating its genetic material. It is the correct process used to genetically change microbes to produce animal proteins.

D. Selective breeding: This involves choosing specific organisms to breed based on desired traits. It is not used to directly alter the genetic makeup of microbes to produce specific proteins.

In summary, genetic engineering is the process used to genetically modify microbes to produce animal proteins.
