Answer:

Contains large polytene chromosome that permit visual inspection of genomic events.

Were used to study the genetic effects of mutations.

Were used to establish the concept of chromosomal inheritance.

Explanation:

<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.

Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.

Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.

Thus, the selected options are correct.

Answer:

Axis - B

Rotation - E

Revolution - D

Latitude - A

Gravity - C

Explanation:

The axis is the line that a body spins on. The axis will line up with the north and south poles. For Earth, the axis is tilted, which is why seasons exist.

The definition of rotation is "the action of rotating around an axis or center." So, rotation is the spinning of a body on its axis. On Earth, one rotation is equal to one day.

Revolutions are when a body spins around another. For Earth, one revolution around the sun is one year

Latitudes are invisible lines that separate the world into degrees from North to South. They are also called parallels.

Gravity is the force that keeps things together. Large masses have gravity that attract other masses.
