Answer:

The environment plays a role in a mutant allele in a population because some mutations are more beneficial to the organism than other mutations.

Explanation:

Organisms with a beneficial allele mutation will be able to pass on their genes as they reproduce. The mutation makes them <em>fit</em> for survival in their environment. Other organisms <em>without </em>the beneficial allele won't be able to pass on their genes since it will be more difficult for them to survive in their environment. Natural selection will deem that the organisms with the mutation will survive better and be able to produce offspring with the same mutation.

Protozoans are best described as uni-celled eukaryotic organisms, both free-residing or parasitic, which feed on organic matter together with different microorganisms or organic tissues and particles. back then, the protozoa have been seemed as "one-celled animals," because they regularly possess animal-like behaviors, together with motility and predation, and lack a mobile wall, as discovered in plant life and plenty of algae.
