Answer:
If I can deternine the field-of-view diameter, it makes it easy for me to determine the size of an organism in the field of view.
Explanation:
The advantages of knowing the diameter of the field of view at a given magnification are that I can have a mental picture of the approximate size of how large the specimens are when I can’t certainly determine them with a simple ruler and the metric system. It also enriches me with a good concept of vital ideas of the size of my samples and the size of what’s the organism.
Answer:
The correct answer is - develop new methods to test the hypothesis.
Explanation:
Human produce offsprings long time and development also take a long time in general and then to test a hypothesis, regarding the gene therapy helps to treat a disease, would take even more time.
So testing this hypothesis required developing a new method as other options are not possible. You can not change the time it takes in reproduction. Giving up is not the option in science.
B) Lysosome.
hope this helped!

A prophage is a bacteriophage (often shortened to "phage") genome inserted and integrated into the circular bacterial DNA chromosome or exists as an extrachromosomal plasmid. This is a latent form of a phage, in which the viral genes are present in the bacterium without causing disruption of the bacterial cell.
