<span>The student who use the hemoglobin data to conclude that mice and shrews are more closely related than mice and humans or shrew and human is quite correct. Scientists had found a way of determining the evolution histroy of animals by means of the amino acid sequence of their hemoglobin. The higher the number of related amino acids found the closer the relationship between the two organisms. There are a difference of 29 amino acid between man and mouse and a difference of 24 amino acids between human and shrew but only a difference of 5 amino acid between mouse and shrew.

Objective has the largest depth of field.
TiliK225 [7]

Answer:

The correct answer is option - C. low power objective.

Explanation:

In microscopes, low power objectives have a wide field of view and use to study the many smaller specimens or large specimens. 10X is the power of the low objective.

To study the depth of the field the lower objective rotated and aligned on the place over the specimen. When you move to high power objective the field of view gets close in and only can study the smaller specimen or small section of a large specimen.

Thus, the correct answer is option - C. low power objectives.
