Explanation:
A hormone is a biologically active chemical substance, synthesized by a glandular cell secreted into the internal environment where it circulates, acting remotely and by blood on receptors specific to a target cell. It transmits a message in chemical form and therefore plays a role of messenger in the body.
The emitting organ thus acts at a distance on all of the target organs of the organism or of neighboring organisms of the same species, or even of symbiotic organisms whose receptors are activated in contact with specific hormones (lasting interactions).
"an increase in predators" would likely lead to an increase in genetic variation in a population of squirrels, since the squirrels would have to adapt to the new threats.
Used in biology to figure out the genes that may be transferred from parent to child. Although this square doesn't determine the exact genes, it helps predict the chance of the child having particular genes.
