A substance that can donate a H+ ion is called an acid

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.
We
all know that vascular plants really have many advantages. These refer to trees
and flowering plants which really gives us what we need. While nonvascular
plants are those small and simple plants which do not have any phloem or xylem.
