Answer:D

Explanation: Because it has the least amount of density in it. All the others are heavier, meaning they will sink. Just like if you drop a rock water and a feather, the feather will float.

Density def:

Density, mass of a unit volume of a material substance. ... Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).

Explain why organisms need enzymes to survive.
kotykmax [81]
<span>Enzymes are catalysts in chemical reactions. What this means is that they speed up chemical reactions, which in turn means that all the actions necessary for our metabolisms occur as a result of catalysts. This goes from fighting illnesses and diseases to dissolving food. We couldn't live without them because our metabolisms would be so slow that we would die as nothing could work.</span>

Answer:

16. Directional Selection

17. Disruptive Selection

18. Stabilizing Selection

19. Natural Selection

20. Adaptation

Explanation:

In population genetics, directional selection/positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes.

Disruptive Selection would show phenotypes (individuals with groups of traits) of both extremes but have very few individuals in the middle.

Stabilizing Selection. Occurs when individuals at the extremes of the range of characteristic are selected against. This means that the "average" individuals are selected for.
