If Adenine always pairs with Thymine and Guanine always pairs with Cytosine, what % of DNA would be made up of Cytosine if 20% was made up of Adenine?
A. 20 B.30 C.40 D.60

option b is correct

Explanation:

if adenine is 20% so thymine is also 20% because equal amount thymine and adenine make a base pair the remaining percentage is 60% which is contributed by cytosine and guanine so cytosine contribute 30% and cytosine also contribute 30%

the answer is:

carbon dioxide

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
