Aplant can open or close its stomata in response to environmental conditions. which best explains how the ability to open and close stomata benefits a plant? a. during a rainstorm, stomata can be opened to absorb additional water through osmosis. b. during a drought, stomata can be closed to prevent excessive water loss through transpiration. c. during the nighttime, stomata can be opened to release the carbon dioxide produced by photosynthesis. d. during the daytime, stomata can be closed to increase the rate of photosynthetic reactions.

The correct answer is B. During drought, stomata can be closed to prevent excessive water loss through the process of transpiration.

Stomata are tiny pores or openings which are in plant tissue and they allow exchange of gas. They are found in the leaves of a plant.

Guard cells helps in the opening and closing of stomata. The pores allows in, carbon dioxide into the plant which is well known as needed during the process of photosynthesis.

They help in reducing water loss and that is why the leaves close when it is dry or hot. The closing and opening of stomata helps in the process of transpiration.

The answer is B. During a drought, stomata can be closed to prevent excessive water loss through transpiration.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
