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.
<span>The lungs are the organs that are most crucial in
expelling cellular carbon dioxide waste. Lungs are the most important organ of
the respiratory system. They excrete these wastes through the process of
diffusion and exhalation. Without the proper excretion of carbon dioxide by the
lungs, the blood will be left without oxygen and might be toxic to course
through the bloodstream. The lungs are responsible for converting unoxygenated
blood into oxygenated blood. Through this process carbon dioxide is expelled as
the by-product.</span>
<span>the plates located at our planet's surface move because of the extreme heat in the earth's core that then leads to the molten rock in the mantle layer to move. it moves in a pattern called a convection cell, it forms when warm material rises, cools down, and eventually sinks down. </span>
Answer:
A nerve impulse
Explanation:
It's important to note that these signals not only connect the brain and spinal cord, but they also send signals to muscles and glands. People talk about nerve impulses when they talk about the electrical signal that goes down an axon.
