Answer:
B. The available donors and acceptors will induce gene expression of their redox enzymes, thereby allowing their use
Explanation:
Electron transport chain is the important stage of cellular respiration where the electron is donated by certain redox molecules.
The ETC takes place in both the aerobic and anaerobic type of respiration wherein the aerobic respiration, oxygen is used as the electron acceptor whereas in the anaerobic respiration some other molecules like sulfate and nitrate are used.
In anaerobic respiration, the type of electron donors and the donor-acceptor molecules determine the fate of the chain as these molecules act as an inducer of the genes of redox enzymes and the genes for the enzymes are expressed.
Thus, Option-B is correct.
Answer:
They don't eat
Explanation:
Simply put, adult Mayflies do not eat. They live for a very short span and their only purpose of survival at this stage is reproduction. Once they reproduce, they die. Some species will last only for 24 hours in the adulthood.
I hope this helps and that you have a great day! :)

The society makes laws to restrict some researches, is the right answer.
In the context of the modern world; where every day new inventions are taking place, it becomes necessary for the government and the society to take some measures to control science. When the society found science harmful like euthanasia, unethical (abortion) or threatening, society makes laws to restrict some research; as these spheres closely associated with culture, religion, and society.
The answer is A; all of the above
