Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.
Answer: Frequency dependent selection.
Explanation:
Frequency dependent selection can be defined as evolutionary process by which the fitness of the phenotype or genotype is dependent on the genotype or phenotype of the composition of the given population.
Frequency dependent selection is the result of the interaction between the species( parasitism, competition or predation)
It can also lead to the dynamical chaos when the fitness of the individual becomes very low.
