Answer:
The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells.
Explanation:
When the vessels suffer vasoconstriction, the blood supply is decreased and in this way the heat of the body is maintained. The way this happens is because the blood can no longer reach the surface and therefore decreases outward heat radiation. The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells. There are several factors that cause vasoconstriction, internal or external. Environment is one of the external factors, and what happens to the penguins' feet is an example for it, since they are trying to preserve body heat to survive.

Budding is the asexual reproduction process conducted by coral and yeast
The daughter cells for mitosis are identical, for meiosis are different cuz crossing over has occurred.
events that occur in meiosis, but NOT mitosis include homologous chromosomes that are pairing/crossing over along in the metaphase plate.
Bacterial spores or endospores are not for reproduction. They do not improve the total number of bacterial cells. Whereas for fungal spores, they are formed from aerial hyphae. They can either be asexual spores which when germinated will be a new but genetically identical to the parent. Sexual spores result from the combination or mixture of nuclei from two opposite mating strains of the same species.
