In April, a population of frogs in a local ravine had a population of 42, which was increased in May by 263 tadpoles.  Pesticide runoff killed 26 tadpoles, and predators consumed 8 frogs.  In July construction workers began clearing the ravine and ran over 12 frogs.  Calculate the population growth rate of the frogs in the ravine from April to August. 

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.
