"While bird watching, Carl hypothesized he could identify 73 different types of birds in one day. He actually identified 65 different types of birds. What was his percent error

15.87%

Explanation:

Carl's percentage error would be 15.87%.

From the data, the hypothesized number of birds Carl could identify is 73.

The actual number of birds he was able to identify is 63.

The margin of error between the two = 73 - 63 = 10.

Hence, percentage error = error/true measurement x 100%

               = 10/63 x 100% = 15.87%

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.
