<span>The possible effect of muscle fatigue is being experienced when muscles are unable to generate force.
This occurs when muscle ATP is being in the process of metabolism of biomolecules. For example sugar and fats.
ATP generates muscle contraction. Muscle fatigue occurs when ATP is being depleted and results in strenuous exercise.
There is also lactic acid accumulation and oxygen depletion.</span>
Answer:
c. Directional selection
Explanation:
Directional selection is a type of natural selection that occurs when selective pressure favors one extreme phenotype over any other phenotype existing in a population. Only one extreme phenotype is favored over time.
A good example of directional selection is the natural selection that occurs in giraffes, where alleles for long necks were favored against alleles for short necks as a result of selection pressure among the different phenotypes. Over time, giraffes having long necks dominated the population as the distribution of length of neck shifts towards the phenotype for long necks.
