The answer is because it lowers the number of chromosomes in half, ensuring that the fusion will have the appropriate amount of chromosomes after the fusing of the sperm and the egg.
It would be the 3rd option: Reaction to a stimulus helps maintain homeostasis.

The answer is (b.) ATP and calcium
ATP (Adenosine triphosphate) and Calcium participates in the muscle movement. In a muscle contraction, Calcium ions are released to initiate upon the depolarization of the membrane which is induced by nerve impulses. While the ATP is required to the shortening of actin and myosin filament crossbridges.
Haploid Gametophyte, in mosses, is the green leafy portion represents which generation in the alternation of generation. Gametophyte is the stage in the life cycle of algae and plants that undergo alternation of generation and it is also the sexual phase in the life cycle of algae and plants.
Answer:
The genetic information in DNA is carried to the cytoplasmic protein-manufacturing centers in form of mRNA.
Explanation:
The process of transcription forms RNA using the DNA template strand thereby copying the genetic information of DNA into the nucleotide sequence of mRNA.
The mRNA leaves the nucleus and enters the cytoplasm to join ribosomes. The nucleotide sequence of mRNA is read in the form of triplet codons to specify the amino acid sequence of the proteins.
In this way, mRNA serves as a carrier of the genetic information in DNA.
