Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
In the<em> </em><u><em>fall,</em></u> a tree's will change color and fall off. Later in the<em> </em><u><em>winter,</em></u> the tree will not have any leaves and will be dormant. Soon the seasons change again. In the <u><em>spring,</em></u> leaves will start to grow back, and flowers will bloom. In the <u><em>summer,</em></u> leaves will stay full and green.
