(1 pt) which of the following is one way that the circulatory system maintain body temperature? a. carrying heat around the body b. controlling the flow of blood to the skin c. carrying nutrients and energy to cells d. speeding up the blood flow to generate heat

The right answer is B. controlling the flow of blood to the skin

When the body temperature is below the set point, the hypothalamus activates several thermogenesis mechanisms:

* Vasoconstriction on the vessels near th skin by the sympathetic nervous system to reduce thermal exchanges between the skin and the surrounding environment.

* And increase in heat production:

-by muscular activity:

-by the metabolism:

d.

explanation:

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.
