Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.

Person because people have genes<span />
Answer:
A) The aim of the experiment is to test the plant for photosynthesis.
B) Sodium hydrogen carbonate is known to increase the amount of carbon dioxide supply to the plants. Hence, it the availability of sodium hydrogen carbonate ensures that carbon dioxide is not the limiting factor for the experiment.
C) Submerged water plants are used because using these plants makes it easier to measure the rate of photosynthesis. Water and carbon dioxide become readily available to the plant which are the reactants for photosynthesis.
Answer: Skeletal Muscle
Explanation:
Skeletal muscle is a form of "striated" (striped) muscle tissue. It is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.
