Answer:

The most probable answer is answer choice : A

Explanation:

"Variation in a population leads to increase in likelihood of success during environmental changes." is the answer because if there were a larger amount of species in the/ a(n) area, then the probability of them going extinct is likely to decrease.

It's like if you want ice in your drink!

If you have 3 ice cubes in you drink then it is likely that the ice cubes will disintegrate, and not cool your drink, but if you have a larger amount of ice cubes, then not only is your drink chilling, but your ice cubes will still be there, but smaller.

In a population, surrounded with dark gray rocks, there lived 2 types of beetles, a gray beetle and a white beetle. In the start

Directional selection favors one of the extreme phenotypes over the other one. <u>Option C is correct</u>. Natural selection is the evolutive force, and 0.40, 0.40, and 0.20 are the new genotypic frequencies.

<h3>What is directional selection?</h3>

Directional selection is one type of natural selection. Let us remember that natural selection is an evolutive force.

Directional selection increases the proportion of individuals with an extreme phenotypic trait.

There must be a selective pressure or environmental pressure acting on populations to lead the species to increase the number of individuals expressing that extreme phenotype.

This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.

In the exposed example,

  • two original phenotypes ⇒ gray and white
  • substrate color ⇒  dark gray rocks
  • environmental pressure ⇒ birds preying on beetles

- Grey beetles managed to camouflage with rocks since their gray color was similar.

- White beetles were exposed on the dark gray rocks, so they were easily seen by birds.

- Predation by birds was an environmental pressure that had a stronger influence on the white phenotype.

Natural selection favored gray-colored beetles, who could survive and reproduce.

Assuming a diallelic gene expressing complete dominance codes for beetles color, we can suggest that the frequency of one of the homozygous genotypes increased, while the other decreased to near cero. Heterozygous individuals kept the allele coding for the white phenotype.

Among the options, <u>C is the correct one</u>. Natural selection is the evolutive force, and 0.40, 0.40, and 0.20 are the new genotypic frequencies.

Why are producers so important
katen-ka-za [31]

Answer:

C

Explanation:

Producers are also known as autotrophs, which they make their own food. Producers capture sunlight energy and use it to convert CO2 (carbon dioxide) and H2O (water) into O2 (oxygen) and C6H12O6 (glucose) for other organisms to use. This process is called photosynthesis.
