Answer:
A. two haploid gametes fuse to form a diploid cell
Explanation:
Meiosis is a type of cell division. When a parent cell with "2n" chromosomes enters the process of meiosis, four daughter cells each with "n" chromosomes are formed. This occurs since homologous chromosomes separate from each other during anaphase-I. However, meiosis does not include the fusion of two haploid cells. The fusion of two haploid cells mainly occurs during the process of fertilization during which a haploid male gamete and a haploid female gamete fuse to form a diploid zygote.

Answer: ionotropic; metabotropic
Explanation:
A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.
Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.
The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
Answer:
b
Explanation:
Genetic Organization of Prokaryotes Aids Fast Generation Times. Compared to eukaryotes, prokaryotes usually have much smaller genomes. On average, a eukaryotic cell has 1000 times more DNA than a prokaryote. This means that less DNA must be replicated (copied) with each cell division in prokaryotes
