Answer:
Take two potted plants and provide equal conditions to both.
Explanation:
Two potted plants i.e. one is placed near the nuclear accident site while on the other hand, the other is placed far away from the nuclear accident. Provide equal conditions to both plants so that we can find out the hypothesis that the frequency of mutations decreases with the organisms distance from the source of radiation. The result shows that the potted plant that is located near to the nuclear accident site having high frequency of mutation as compared to other plant due to the radiation present at that location.

Explanation:
Carrying capacity is the maximum size of the population of a species that an ecosystem can handle based on the availability of resources.
A limited factor is the factor that can be an abiotic or biotic agent is likely to affect the life of the living being.
American pikas are the small rodent-like mammals. These animals are short and stout. They have big, round ears and do not have tails. They have a brown and black coloration which helps them to hide behind the rocks and camouflage the predators.
Here, the decreased in rock fragments is a limiting factor which will increase the carrying capacity of American pikas. Due to lack of rock fragments, the American pikas will not be able to hide from predators and they will die. The size of the population will become by the supportive carrying capacity.
