What do you predict would happen if hydrogen bonds formed between any two nitrogenous bases in dna?
dna replication would happen much more quickly.
dna replication would happen at a slower rate.
fewer mutations would occur during dna replication.
identical copies of the original dna would not be formed.

The correct answer is "Identical copies of the original DNA would not be formed".

Explanation:

Hydrogen bonding between nitrogenous bases in DNA is one of the characteristics that makes unique the sequences of DNA. This is known as complementary base pairing, at which in regular conditions cytosine could only bind with guanine by forming three hydrogen bonds, and adenine with thymine by forming two hydrogen bonds. If hydrogen bonds could be formed between any two nitrogenous bases in DNA, the formation of identical copies of the original DNA would not be possible. DNA polymerase identifies the next nucleotide during polymerization by complementary base pairing, if this mechanism did not exist DNA polymerase would not be able to make identical copies of DNA.

the answer for this question would be d. glaciers

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
