Which of the following is NOT a correct base pair?

A-C
T-A
C-G
A-T

A-C

Explanation:

Hello There!

Remember these are the complementary base pairs

Adenine and Thymine (so the 2nd and 4th one are correct base pairs)

Cytosine and Guanine ( so the 3rd one is a correct base pair)

Hence, A-C would be the incorrect base pair because like stated previously Adenine pairs with thymine not cytosine

answer; ///i believe the correct answer is (aids) acquired immune deficiency syndrome;

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
