Enzymes (plants, which are eukaryotes, have chloroplasts)
I think the answer is due to ph. levels in the soil
Prophase- <span>chromosomes become visible as paired chromatids and the nuclear envelope disappears.
metaphase- </span><span>chromosomes become attached to the spindle fibers.
anaphase- </span><span>chromosomes move away from one another to opposite poles of the spindle.
telophase- </span><span>the final phase of cell division in which chromatids, or chromosomes, move to opposite ends of the cell and two nuclei are formed.</span>
Trisomy=3 chromosomes; 1 more than the required pair (2)
21=the type of chromosome
So, here we can eliminate A and B.
Now we have C and D.
I know that when sperm cell(s) simultaneously fertilize [an] egg, a class of identical twins will form. Therefore, we can eliminate D, leaving us with merely C. Henceforth, C is your final answer.
