A theory in science is a remark on what happened
This is because the cells we need for reproduction need to be genetically different from those of the rest of the body.
Cellular reproduction
When a mother cell divides into two or more daughter cells, this process is known as cell division. Cell division frequently takes place as a component of a longer cell cycle. There are two different types of cell division in eukaryotes: a vegetative division (mitosis), in which each daughter cell inherits the genetic makeup of the parent cell, and a reproductive division (gametogenesis), in which the number of chromosomes in the daughter cells is cut in half to produce haploid gametes (meiosis). In cell biology, the process of mitosis, during which replicated chromosomes are split into two new nuclei, is a stage of the cell cycle. The number of chromosomes is maintained in the genetically identical cells produced by cell division.

Answer:
The rift valley formed when the crust pulled apart.
Explanation:
The statement that best describes how the Great Rift Valley in Africa formed is that they formed when the crust pulled apart.
- This is geologically known as divergence.
- The Arabian plate and the Nubian/Somali plate are divergent plates.
- They are currently moving apart and away from each other.
- This creates a crack on the earth which is what formed the rift valley in Africa.
- Along such margins, earthquake activities are prominent.
