11. You are a research scientist for the National Institutes of Health (NIH) interested in performing
a controlled experiment to determine the effects of caffeine on human blood pressure. One group
of people will get caffeinated coffee and one will get decaffeinated coffee. Briefly explain why
you would want that to be the only variable that differs between the two groups.

where is the diagram?

if you insert the diagram ill be able to you

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.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
