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 & Explanation:
Aquatic plants don't have to deal with drying stress, so, for example, the number of stomas will be lower or even absent. Also, the pressure and temperature conditions underwater are way different than on earth. Therefore, the movement of fluids and metabolic products will be quite different.
Answer:
True
Explanation:
For example, NaCl - sodium chloride, when dissolved in water forms Na+ and Cl- ions.
A phosphate group and single nitrogen containing based
Question: Which of the following are appropriate units for power?
A) newton·meter
B) watt
C) H.P./sec
D) joule/sec
Answer:
Watt and Joule/sec are the appropriate units for power.
Explanation:
As per the question, the physical quantity given is power.
The power is defined as the rate of consumption of energy or the rate of doing work.
Let us consider W is the amount of work done by a body in time t .
Mathematically the power of that body is written as -
power 
The unit of work is joule and the unit of time is second.
Hence, the unit of power is joule/sec.
we know that one joule/sec. = one watt.
Hence, watt is also another unit of power. Newton-metre can not be a unit of power . It may be considered as a unit of work.
Similarly H.P/sec is also not a unit of power. Here H.P stands for horse power which is another unit of power . Hence, joule/sec. and watt are the appropriate units of power.
