There would be four gametes, because meiosis produces four genetically different haploid gamete cells.
The statement that best describes the dust gas and celestial bodies of the Milky Way galaxy is that -<u>They orbit around the center of the galaxy because of gravity.</u>
<u />
Explanation:
- <u>The Milky way is referred to as a spiral galaxy ,our sun,and all the planets are a part of this galaxy.</u>
- <u />
- <u>A galaxy is often said to be a large group of dust gas and celestial body (i.e nebula, stars, comets, meteors, asteroids, and planets.) bounded together with gravity.</u>
.
So we can say that the statement that best describes the dust gas and celestial bodies of the Milky Way galaxy is that -<u>They orbit around the center of the galaxy because of gravity.</u>

Loss of Rb, an important part of the G1-S transition checkpoint, can result in uncontrolled cell cycle progression and cancer. All of the following would mimic loss of Rb except constitutively active Ras GTPase activating protein. Correct answer: letter E.
Constitutively active Ras GTPase activating protein would not mimic loss of Rb, because it would not directly result in uncontrolled cell cycle progression.
<h3>What is Retinoblastoma (RB)?</h3>
Rb is an important tumor suppressor protein that works to inhibit cell cycle progression by preventing the activation of E2F transcription factors. Constitutively active Ras GTPase activating protein would not directly interfere with the Rb-E2F pathway, which is necessary for uncontrolled cell cycle progression and cancer.

The benthic organism is an organism that lives on, in or near the seafloor. This also helps the environment and marine life by providing structure, alter water currents, and stabilize shorelines, hard substrate settlement. Some recycle nutrients and improve water quality. An animal of a large group distinguished by the possession of a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fishes.
