Answer:
The answer is E.
Explanation:
In vivo or in vitro evolution (Directed Evolution) is a technique used by genetic scientists to push the change in nucleic acids or proteins in a specific direction to get the end results that they want.
And high-fidelity polymerase is used to get a replica of the target DNA that has less errors.
So the situation given in the question where researchers use a higher-fidelity DNA polymerase in vitro evolution, the mutation rate would most likely be lower because of the high-fidelity DNA polymerase.
I hope this answer helps.
Hello. This question is incomplete. The full question is:
"Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cell. Could you explain that observation?
"
Answer:
You are visualizing the onion cell during mitosis interphase. At that time, cells may have multiple nuclei and some of them may not be visible near the cell wall.
Explanation:
Experiments with onion roots are common when we want to visualize the phases of the cell cycle or to visualize chromosomes and cell nuclei.
If after the experiment with an onion cell you are unable to visualize the cell nuclei near the cell wall, it means that you are visualizing the cells during the interphase of mitosis. At that time, cells may have multiple nuclei and some of them may not be seen near the cell wall.

Interstate 95 seem to follow the fall line because it was designed to go around rapids and waterfalls
Explanation:
The extreme side of the coastal plain of Virginia that has a chain of rapids and falls as its mark and which has rivers flowing around it is remarkably known as – Fall line. This observation was performed by John Smith first. This line has remarkable impact on Virginian geology.
The line of falls around it prevented the way of ships and led to the formations of some cities of Virginia. The connecting line of major cities of east coast, the Interstate 95 runs parallel to the fall line. This actually seems that it follows the fall line.

Punctuated equilibrium is a series of small, gradual changes over long periods of time.
