I think the correct answer from the choices listed above is option A. Directional selection can be distinguished from disruptive selection by the elimination of extreme variations of traits. Directional selection is a natural selection where an extreme phenotype is favored than others.
The prokaryotic cells contain more DNA
The environmental benefit of the leaf canopy of a tree slowing down the impact of raindrops and the root system absorbing water and holding soil in place would be that the water erosion of soil would be minimized.
The washing away of topsoil by water is termed water erosion. This event has a number of impacts on the ecosystem, including:
- reduced agricultural yields
- damages to infrastructures such as roads
- washing away into nearby water bodies can cause eutrophication
- water quality of nearby water bodies becomes impacted negatively
The leaf canopies of trees prevent raindrops from having maximum impact on soil structure while the roots of trees absorb water and also holds soil structure together to limit water erosion of the soil. This will in turn prevent negative consequences to the environment.
