The answer is the first choice:
Negative feedback reverses a change in a variable that has moved outside of its normal range, whereas positive feedback strengthens it.

Feedback loops do not only apply to blood pressure. There are many examples from body temperature regulation to child birth to your AC unit at home.

If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?

Serggg [28]

Answer: 4 Guanines

Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.

We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
