Answer:
B. Multipotent cells
Explanation:
Multipotent stem cells are the one that develops from pluripotent stem cells during embryonic development. The multipotent stem cells are the stem cells which have specific functions. These cells develop into specific cell types to replace the older cells.
For example, keratinocytes are the multipotent cells of the skin that produce new skin cells. Spermatogonia are the multipotent cells present in testes so that they can form sperms.
The right answer is Haploid cells join to form an organism that has a complete set of chromosomes.
Meiosis makes it possible to pass from a cell to 2n chromosomes to 4 cells with n chromosomes, thus ensuring the passage from the diploid phase to the haploid phase.
So from the fertilization phase to the meiosis phase, the cells will be diploid (2n chromosomes). From the meiosis phase to the fertilization phase, it is the haploid phase (n chromosome).
Use pesticides, kill the cockroaches
use cockroaches for research XD
and other than that, live in harmony with them i guess?
nothing else you could really do about it
