Tanya [424]3 years ago
8 0

Answer:

B

Explanation:

The four nitrogenous bases in DNA are A: adenine, G:guanine, C: cytosine, and T: thymine.

Pyrimidine and purine are the two classes of the bases in DNA and RNA, not the actual bases themselves.

Uracil is a nitrogenous base found in RNA, that is switched for thymine in DNA. It is not found in DNA.

Therefore, the correct answer is B: Adenine, guanine, cytosine, and thymine

Phoenix [80]
This startle reflex (aka moro reflex) is/was present in us as newborns.

It's triggered when there's an unexpected reaction. Example: Loud noise, sudden movement.

The baby will tighten his/her body, fling out arms, sort of like giving him/herself a hug. It happens because the baby is trying to protect itself from harm.

It normally leaves thanks to the mother's care, normally 6 weeks after the newborn is born.
