5 0

The correct answer is B. The science of inherited traits

Explanation:

Genetics refers to the field in biology that focuses on studying genes which are the basic units of heredity and therefore the ones that determine inherited traits. Indeed genetic study the way traits are passed through reproduction and also the way genes change over time or express which is closely connected to evolution. Additionally, genetics have been widely studied beginning by the works of Mendel during the 19th century and nowadays the knowledge about genes including the behavior, function, and structure of them is broad. According to this, genetics is defined as the science of inherited traits.

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.

How many amino acids differ between the monkey and the human sequences?
Gwar [14]

Answer:

8 amino acids differ between the monkey and the human sequences.

Explanation:

The genome mapping has now made it possible to identify genes that are present on a chromosome. Genetic mapping is also being used to study the similarities between organisms which has helped a lot to understand the evolutionary history among organisms and to assemble the phylogenetic lineages.

Scientists have found the genome of the monkeys to be the most similar to humans with a difference of just 8 amino acids between them. Hence, justifying the hypothesis that humans have evolved from monkeys.
