A population of lizards lives in a rocky area next to a desert. Some lizards are light colored and blend into the sand. Others a
hjlf

Answer:

c. They may evolve into two separate species as a result of disruptive selection

Explanation:

Disruptive selection is a type of natural selection wherein some extreme change in the surroundings favor two distinct phenotypes while trimming off the mean. Here, the environmental conditions favor more than one phenotype. In the given example, disruptive selection would favor the light-colored lizards in the sandy region while the dark-colored would be favored in rocky regions due to their respective survival success.

With time, these two populations would accumulate more variations and reproductive isolation would not allow them to interbreed and thereby two distinct species of lizards would evolve.

In an ecosystem where the owls eat mice the carrying capacity of both populations has been reached . how would the migration of
zhuklara [117]

Answer:

<em>It would cause a decrease in the carrying capacity of the owl population.</em>

Explanation:

The relationship between a predator and prey is unique. Both the population of a predator and prey gets affected if changes in one of them occur.

If mice migrated from the ecosystem, this will mean that there will b little food available for the owls on that ecosystem. As a result, they will compete for food. Some of them would get killed due to lack of food. Others will migrate to places where they can find food. Hence, the carrying capacity of the owl population would decrease.

Explain how natural selection could lead to a change in allele frequency leading to a change in the color of the frogs.
Pie

Answer:

Due to increasing the survival.

Explanation:

The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.
