Answer:

<u>Villus- </u>It is a worm like processes on certain membranes, especially on the mucous membrane of the small intestine, where they serve in absorbing nutriment.

<u>Capillary-</u>Any of the fine branching blood vessels that form a network between the arterioles and venules.

<u>Alveolus- </u>These tiny, balloon-shaped air sacs sit at the very end of the respiratory tree and are arranged in clusters throughout the lungs.function it is to exchange oxygen and carbon dioxide molecules to and from the bloodstream.

<em>Now, they are all present at a very basic level and some how there are similarities between there nature of operations.</em>

Explanation:

  • Both alveoli and villi help in increasing surface area of the respective organ.   As they increase the region of operations for the respective organ, on which they are present on.
  • As both alveolus and villus  are associated with extensive blood capillary network for diffusion of important substances into blood: namely oxygen and dietary nutrients.
  • And the most important thing all of them are present on a minute level of the bodily operations.

Two species of closely related frogs are found in the same pond high in the Andes of South America. Both species only have teeth
IgorLugansk [536]

Complete question:

Two species of closely related frogs are found in the same pond high in the Andes of South America. Both species only have teeth on the top jaw. One has small teeth for holding small live prey prior to swallowing. The other species has very large sharp teeth for injuring and killing large prey prior to biting off pieces of flesh for consumption. The above is an example of:

  • Directional selection
  • Analogous structures
  • Character displacement
  • Hybridization
  • Vestigial structures

Answer:

  • Character displacement

Explanation:

Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When <u>two competing species coexist, this is because of niche partitioning or niche differentiation</u>.

Differentiation of effective niche is closely related to <u>character displacement.</u>

<u>Character displacement</u> is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.

In the exposed example, both species live in the same pond. But to avoid competition and competitive exclusion, species developed different teeth sizes to feed on different prey items.
