Answer:
The correct answer is - True.
Explanation:
The negative feedback loop of the endocrine system is that when a hormone is inhibited by its own mechanism or its products. The negative feedback mechanism in the blood is when the level of testosterone and inhibin inhibit the release of the GnRH, LH, and FSH. The low level of GnRH, LH, and FSH affects spermatogenesis and ovulation in males.
In females, the high levels of estrogen and the progesterone exhibit the negative feedback hormone prevents LH and GnRH production by acting on the hypothalamus and inhibit ovulation.
Thus, the correct answer is - True.

Selective toxicity refers to the ability of the drug to targets sites that are relative specific to the microorganism responsible for infection. Sometimes these sites are unique to the microorganism or simply more essential to survival of the microorganism than to the host.
-Antibacterial action generally falls within one of four mechanisms, three of which involve the inhibition or regulation of enzymes involved in cell wall biosynthesis, nucleic acid metabolism and repair, or protein synthesis, respectively. The fourth mechanism involves the disruption of membrane structure.
Answer: C
Explanation: DNA polymerase is the enzyme that matches and lays down nucleotides to build the daughter DNA strand along each parent DNA strand. Now we're left with all these Okazaki fragments that are separate from each other, so they need to be joined together by the enzyme DNA ligase
