Chromosomes come in pairs (2n) in somatic cells or cells of the body. For instance, the number of chromosomes of a human being is 46 (23 pairs of chromosomes). In the event of sexual reproduction, gametes (sperm and egg cells) contain the same number of chromosomes as somatic cells then the union of the sperm and egg will produce twice that of normal (4n) chromosomes and will render reproduction inconsistent or even impossible. Therefore, a conclusion is made that in the cellular division of gametes, the chromosomes should be reduced in half in order to produce the same number of chromosomes for somatic cells generation by generation.

The body monitors fat stores by assessing levels of the hormone ____, which is produced and secreted by fat cells.​
Ivan
<span>Leptin. Leptin is produced by fat cells and released when your body has enough fat in storage. When leptin reaches the brain, it gives your body a feeling of fullness so that you will not want to continue eating. Individuals with leptin resistance, where the leptin hormone signals are not received as they should be, are often overweight because they do not have the same brain signals telling them that their body is full.</span>
