Answer:
<h2><u>
directional selection</u></h2>
Explanation:
This type of natural selection is referred to as . In this type of natural selection, either one phenotype is preferred or the other; therefore, there is no equilibrium between the populations of the phenotypes that are present.
Examples of organisms that have undergone directional selection are black bears during the ice ages, African chichlid and sockey salmon.
Hello,
Convection currents<span> in the mantle drive plate tectonics. Convection is the reason for o</span>cean currents. Ocean currents<span> result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.
</span>
Both the mantle and ocean experience <span>the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.

Both are used for energy to the body.
