Answer:
"This is a specific example of a reproductive barrier, called behavioral isolation or sexual isolation".
Explanation:
Reproductive barriers are <em>isolation mechanisms</em> that prevent mating between two or more species. The <u><em>prezygotic mechanism</em></u> avoids fertilization between individuals of different species, and the <u><em>postzygotic mechanism</em></u> avoids the zygote to develop and reach the adult stage.
There are different types of reproductive barriers, one of them is <em>behavioral isolation</em>, also known as <em>ethological isolation</em> or <em>sexual isolation</em>. This is a <em>prezygotic barrier</em> that refers to the fact that <em>many species occupy the same area</em> but they are <em>not sexually attracted</em> to each other and might even be rejected <em>because of behavioral factors</em>, and this is why they do not get to mate. This mechanism includes courtship patterns or mating rituals, and specific chemical signals that allow the recognition between individuals of the same species. A typical <em>example</em> is the <em>recognition songs</em> of some species like frogs, birds, insects, and etcetera.

Answer: To see for example an apple first light that passes through the pupil is eventually reflected on the pupil, activating neurons in the retina. light waves that were reflected off the apple are changed into neural impulses (transduction) at the point of the retina, where neurons fire in response to light waves. Action potentials are released when neurons fire, sending an electrical charge through the neuron. Excitatory neurotransmitters are released when the action potential reaches the axon terminal, and that these neurotransmitters increase the chances that the next neuron will fire. Of course the neural message from the retina first passes through the thalamus, and then the thalamus routes the impulse elsewhere in the brain.
