4. which type of cell division is a part of asexual
reproduction?

Explanation:

Binary fission: Single parent cell doubles its DNA, then divides into two cells. Usually occurs in bacteria.

Budding: Small growth on surface of parent breaks off, resulting in the formation of two individuals. Occurs in yeast and some animals (like the hydra below).

Fragmentation: Organisms break into two or more fragments that develop into a new individual. Occurs in many plants, as well as some animals (like coral, sponges, and starfish).

Parthenogenesis: An embryo develops from an unfertilized cell. Occurs in invertebrates, as well as in some fish, amphibians, and reptiles.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

you need to have a picture of the atom that way we can answer it
