Answer:
4. (answered below); 5. 66.2; 6. (answered below)
Explanation:
4. The individual's heart rate increased because the individual needs more oxygen supplied to their muscles so the heart has to pump the oxygenated blood through the body at a faster rate.
5. Take average of the number of the pulse before exercise:
(68 + 70 + 54 + 64 + 75) / 5 = 66.2
6. Different individuals are different sizes and are in different states of health. An individual who is more physically fit will have a slower rate rate because their heart muscle is "exercised" or worked more and pumps blood more efficiently.

Answer: SEMI-CONSERVATIVE
Explanation:
In semi-conservative DNA replication,
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent strand is retained in the newly synthesized DNA, DNA replication is described as semi-conservative
