Answer:
More exposure causes mutation in bacteria.
Explanation:
More exposure to the antibiotic by non-resistant bacteria causes change in its structure against the environment and as a result of that change the bacteria get resistance against that antibiotic. No, farmers should not be allowed to put low doses of antibiotics in animal feed because it has no effect on the antibiotic-resistant bacteria. The farmer should use another antibiotic on the antibiotic-resistant bacteria which they have no resistance.
When insulin is deficient , GLUT4 transporters are not inserted into the cell membranes , glucose is not transported into the cells and the blood glucose concentration increases.
Insulin deficiency provides more amino acid and glycerol substrates for glucose synthesis ie increased gluconeogenesis .
With a deficiency of insulin, there is both increased hepatic glucose production through increased glycogenolysis and gluconeogenesis as well as decreased glucose use. The result is hyperglycemia.

<u>Answer:</u>
<em>The two major processes by which bacterial populations produce genetic diversity are gene transfer and mutation.</em>
<u>Explanation:</u>
Gene transfer in bacteria occurs through conjugation. In the process of conjugation, the plasmid gets transferred from bacteria to another. Mitosis leads to the formation of two identical individuals.
In this process, the chromosome and the DNA content of the daughter cell remains the same as the mother cell. Bacteria also divides by the process of binary fission.
