Leni [432]

Answer:

The correct answer would be B. the population is evolving.

It can be explained with the help of natural selection. It is a natural phenomenon by which organisms which are better adapted to the changing environment have better chances to survive and reproduce.

It leads to a change in the allele frequency of that trait in a population.

For example, in the given population, the allele frequency of red fur increases from 20 to 30 percent. That means the population is evolving to adapt to the changing environment.

saveliy_v [14]

When an external stimulus crosses the threshold, a muscle fibre will respond.

<h3>The level of the threshold</h3>
  • For the identification of the electrical activity carried out by the active muscles, the threshold level is a crucial consideration.
  • A portion of the electrical activity carried out by the target muscles may be excluded if the chosen threshold level is higher than the overall activity.
<h3>What is the stimulus threshold for muscle contraction?</h3>
  • A certain stimulus magnitude is necessary for muscle contraction.
  • The threshold stimulus is the smallest amount of force needed for a stimulus to cause a muscle to contract in response.
  • If the stimulus intensity is less than this threshold value, there is no response.
