Populations of organisms that exhibit a high degree of variation have a greater chance for survival than populations of organisms that show little variation is described below.
Explanation:
- Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
- The genetic variation in the population is increasing due to selective pressure. The genetic variation in the population is decreasing due to selective pressure. The genetic variation in the population is increasing due to gene flow. The genetic variation in the population is decreasing due to gene flow.
- Genetic drift is a random change in allele frequencies. These random changes in allele frequency can accumulate over time. ... Small samples can vary more markedly from the larger sets from which they are selected than larger samples, so genetic drift is more powerful in smaller populations
- Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).

Answer:
Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.
The Auricle or Pinna is the visible curvy part which trap sound to be received into the ear canal which is a passage way for sound until it reaches the ear drum which is a piece of tightly stretched skin and the end of the ear canal. The sound waves vibrate the skin which moves the stirrup, anvil and hammer or altogether known as the ossicles. The ossicles' movement the cochlea which has many tiny hairs. Nerves in the hairs pick up the movement which then gets turned into electrical pulses and sent up through the brain via the auditory nerve to be interpreted.
