Convection can only occur in Liquid and gas form.
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:
Answer is microvilli.
Explanation:
Plasma membrane possesses or comprises of channels , made up of proteins , and form openings for certain molecules to diffuse through and into the cell.
The major function of the microvilli is that it increases the surface area of the cell. This activity increases the rate of absorption, secretion and cellular adhesion.
It should be noted that, microvilli are projections or protrusions found on the cellular membrane.
Answer: C. Gravel
Gravel has the highest permeability.
Anaphase is the answer. In metaphase the chromatids line up next to each other and the spindle attaches to the centroid. In anaphase, the chromatids are pulled apart into opposing sides of the cell by the spindle fiber
