An ecologist in Costa Rica wanted to determine the Population Growth Rate for the country in 2018, and collected all of the data necessary to calculate the rate. She concluded that there were 34560 births and 2310 deaths within their population of 100,000. There were also 478 immigrants and 126 emigrants that year. What was the population growth rate for Costa Rica?

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

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.
