Answer:
A huge number of chemical reactions take place continuously in a living cell. The whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.
Explanation:
All organisms need the energy to grow, reproduce, and respond to their surroundings. All these processes are achieved through metabolism that allows the energy available to them.
Answer: a. dead organisms from the marine food web.
c. liberation through ATP hydrolysis in living organisms.
Upwelling is a wind driven motion of lower bottom nutrient rich and warmer water on the surface of the water body. This wind driven motion facilitates the movement of nutrients available for growth of primary producers like phytoplanktons growing on the surface of water body. The dead organisms from the marine food web get decomposed and the organic matter obtain after decomposition is a rich source of phosphorous. This phosphorous gets transferred to the upper layers of the water body by upwelling. In aquatic organisms ATP hydrolysis occurs which is a catabolic process that uses water to split the bonds present in the ATP molecule and hence, releases energy for functions performed by them along with a release in phosphate atom. This phosphate gets mixed with the water. Therefore, PO32 come from dead organisms from the marine food web and liberation through ATP hydrolysis in living organisms that circulates due to upwelling.
B. ATP synthase. The purpose of the hydrogen gradient is to take advantage of molecules' tendency to move from areas of higher concentration to areas of lower concentration. ATP synthase lets hydrogen ions flow through it to the matrix, and the energy from this flow is used by ATP synthase to synthesize ATP.
Alleles undergo segregation is
present in the mitosis. The answer is B. The first stage is prophase. The
nucleolus disappears and the two centrosomes begin to form the mitotic spindle.
The spindle xtends between two opposite poles f the cell. Next is the metaphase.
The centromeres of the chromatid pairs align at the center of the miotic
spindle. Then anaphase, the centromeres will split that separates the chromatid
pair. In here, alleles are formed. They are now called chromosomes. The last
phase is the telophase. The chromosomes will then form a thread-like chromatin
and for ache envelope, a nucleoli appears.
I am absolutely sure that fish and crustaceans are similar in that both use <span>gills </span>for gas exchange. Even though you didn't share any options to choose the correct one do not hesitate to use my answer, this one is right.
