Answer:
The correct answer is A. stabilizing selection
Explanation:
Stabilizing selection is one type of natural selection that occurs when the population having non-extreme traits are stabilized. It results in overexpression of a particular trait in a population. Here most average individual gets selected.
So as the stabilizing selection favors the middle phenotype and not extreme phenotypes it decrease the genetic variation. So here individuals who are having extremely long snout are selected therefore a particular trait is selected and overexpressed in the population. So it is an example of stabilizing selection.
I believe it is called meiosis
Answer:
By removing the apices of the plant
Explanation:
A plant can be manipulated into becoming more bushy <u>by removing the apices of its shoots.</u>
<em>A plant hormone called auxin which promotes cell elongation and plays a huge role in the maintenance of apical dominance is usually produced at the tips (apices) of stems. When the tips are removed, auxin production is disrupted, and lateral buds that have been initially suppressed by the auxin production begin to flourish, leading to the plant becoming more bushy.</em>
Hence, to trick the jade plant to become more bushy, just remove apices of the shoots the plant.
In biology, a life cycle<span> is a series of changes in form that an </span>organism<span> undergoes, returning to the starting state. "The concept is closely related to those of the </span>life<span>history, development and ontogeny, but differs from them in stressing renewal."</span>
