The nitrogen fixation is a very important process because it is the principal source of nitrogen in the marine environment for photosynthetic plants. Nitrogen is a growth limiting nutrient, that is very important for the growth of photosynthetic plants. During the process of nitrogen fixation, nitrogen is absorbed from the atmosphere and it is fixed by nitrogen fixing organisms.
Aphotic zone of a body of water refers to the part where almost no sunlight. With this condition of water, marine life is limited to species who does not light for survival. The aphotic area also is the basin of the dead organism that submerges from the photic part. Temperatures at these areas are also low.
Answer:
It wouldn't be able to migrate to the cell's poles.
Explanation:
During anaphase, microtubules attach the chromosome's centromeres and start dragging them towards the poles of the cell. In mitosis, this causes the separation of both sister chromatids for each chromosome, and each chromatid migrates to a different pole. In meiosis, first each homologous chromosome is separated by the same process, and then the sister chromatids are separated during anaphase II. If a chromosome doesn't have centromeres, microtubules are unable to attach the chromosomes, and so the separation of either sister chromatids or homologous chromosomes can't take place.
