Question

Help please if you know the answer​

Answer 1

Explanation:

Process A:

Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Process B:

The living differentiated cells that by now have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation. Example: formation of meristems - interfascicular cambium and cork cambium from fully differentiated parenchyma cells.
