The first statement, “We never get to see the far side of the moon” is <u>true</u> among all the statements given.
Explanation:
We only see one side of the moon from Earth, which is commonly referred to as the “near” side of the moon. We are able to see this side through our naked eyes due to the sunlight reflecting of the surface of the moon.
However, this is not to say that the far side of the moon does not receive sunlight at all. It does receive, but it’s just that the far side of the moon never faces the Earth and hence we never see it.
Having said that, the other statements are false. The near side itself goes through weeks of darkness, where it is not lit up by the Sun. The moon has its own axis upon which it rotates. And the moon orbits the Earth and one full rotation takes about 28 days.

Epistasis is the communication and the interaction of the genes. These are not within the alleles but with the genes themselves only. Also known as the genetic background, the genes are dependent on their effect to show the trait. </span>
