Which regions of the river in the figure above contain more nutrients than the other regions? Explain.

Hello. You don't know what this question refers to, but the regions of the rivers that have more nutrients are those that have a lot of algae and vegetables and few fish and marine animals in general.

Explanation:

The accumulation of nutrients in rivers, mainly nitrogen and phosphorus, stimulates the primary production of this environment, which is represented by the excessive growth of algae and other vegetables, which often end up dominating the entire surface of the river. This is very harmful for aquatic animals as it decreases the oxygen concentration of the river, leading to the death of several animals, especially fish. For this reason, we can say that the areas with the most nutrients in a river will have a large number of algae and a low number of fish.

b - the respond is innate and varies over time.

good luck!

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.
