Explanation:
Muscle fibers are elongated cells that can have one or more nuclei. They will form muscle tissues, which can be of three types: striated cardiac muscle, skeletal striated muscle or smooth muscle, each having its own functional and morphological characteristics. However, these types of muscle fibers have in common the ability to generate movement by contraction.
Contraction occurs at the moment of maximum tension of these muscle fibers and a muscle fiber develops its maximum tension when it is at its typical resting length before being stimulated.
The answer is directional selection
It is the mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. The advantageous allele increases in frequency independently of its dominance relative to other alleles; that is even if the advantageous allele is recessive, it will eventually become fixed, changes the average value of a trait. Occurs most often under environmental changes and when populations migrate to new areas with different environmental pressures.
