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.

A group of student set up an experiment to test the effects of exercise on the rate of cellular respiration. During the experime
Rzqust [24]

The answer would be B:The data suggests that exercise increases the rate of cellular respiration because more carbon dioxide was produced.


The data has a consistently show that the time needed to change BTB color in after exercise group is much shorter(less than half) compared to before exercise group. If the time needed longer, this show that the amount carbon dioxide removed from the lungs is much higher. The reaction that provide energy for the muscle will produce carbon dioxide as side product in cellular respiration.

The scientist has a water sample from an unknown location in the lake. When bromothymol blue is added, the sample becomes blue.
Anarel [89]

The aqueous bromothymol blue solution act as a pH indicator and turns blue only in case when the pH of the sample is above or equal to 7.6

Since the pH of the water at the surface of the lakes is higher and ranges between 7.5 to 8.5 the color of bromothymol turn blue.
