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:
The genes for all organisms are composed of the same building blocks.
Explanation:
There are choices for this question namely:
<span>1 Lifelong passive immunity
2 Long lasting active protection
3 Immediate passive short term immunity
4 Stimulation for the production of antibodies
</span>
The correct answer is "immediate passive short term immunity". The administration of tetanus immunoglobulin will directly attack toxins associated with tetanus for a short time, providing short term immunity and this effect is immediate.The passive immunity from tetanus immunoglobulin is not lifelong. Choices 2 and 4 talks about active immunity which is not characteristic of tetanus immunoglobulin injection.
