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:
A falling object reaches what’s known as its terminal velocity when friction — the slowing force of air — cancels the downward pull of gravity. That means the drop stops speeding up and keeps falling at a steady rate. This should be the top speed at which a droplet can move. Yet scientists have observed raindrops plummeting faster than their terminal velocity.
