A type of cell division that halves the number of chromosomes is known as

1 answer:

4 0

The answer is meiosis.

In meiosis, this process produces 4 daughter cells which are all genetically different to each other and their parent cell. They have only half of the chromosomes. This is because, at one point in the process before the cells divide, parent do not copy their genetic information, which ends up each daughter cells only receiving half of the chromosomes after division.

The daughter cells are also said to be haploid, and in human, these cells are usually gametes, which are for reproduction, so that after 2 of these haploid cells join together, the correct amount of chromosomes can be restored.

qaws [65]

Answer:

B) cAMP

Explanation:

Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are are regulators of signal transduction: regulate the duration of signaling pathway.

Caffeine is central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.
