Answer:

b. 80g

Explanation:

Three cycles of PCR would produce 3 doublings of the amount of DNA.

Cycle 1: 10x2  = 20pg

Cycle 2: 20x2 = 40pg

Cycle 3: 40x2 = 80pg

This can also be worked out for large cycle numbers by final mass = starting mass x 2ⁿ, where n is the number of cycles.

A boxer is competing in a match. Which describes the roles of endocrine and neural controls as he boxes?
andrew-mc [135]

Answer:

The correct answer is "The nervous system transmits pain, while the endocrine system elicits the fight or flight response".

Explanation:

One of the roles of the nervous system is to transmit pain to alarm the body that something is going on and that it acts accordingly. The nerve pathway is the one that carries the message of pain from the affected area to the spinal cord and up to the brain. On the other hand, the endocrine system is the one that elicits the fight or flight response. During stressful conditions, the adrenal glands of the endocrine system release epinephrine and norepinephrine that acts during the fight or flight response.

Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells
almond37 [142]
The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.


Hope this helps:)
