Answer 2

The nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate.

Answer 3

The four nucleotides in DNA are: adenine, thymine, guanine, and cytosine. Adenine pairs with thymine while guanine pairs with cytosine.

Answer 4

So your answer would be A

Answer 12

The nucleus of an atom contains ________.
A. electrons and neutrons.
B. protons and electrons.
C. protons and neutrons.
D. protons, electrons, and neutrons

Answer 13

Protons and Neutrons.

Answer 14

germ cells are the cells that go on to become sperm and eggs. If a mutation occurs in them, the resulting organism will have that mutation in every cell of his or her body. Somatic cells are every other cell in the body besides germ cells; none of these cells are passed to offspring, so mutations in them cannot be inherited by the individual's offspring.

The answer is A on the other question

Answer 15

THANK YOU :))

Answer 16

WAIT LOL the answer was D!!!

Answer 17

Somatic cells cant be passed to their offspring
