Answer:
Transposable elements (TE)
Explanation:
A transposon, also known as 'jumping genes', is a particular sequence of DNA that can relocate inside of the genome. It affects the genetic identity and can be made use of to either reverse a mutation or create one - it duplicates that genetic sequence. Retrotransposons is a class of TE found in viruses.

Answer:
The Earth might seem like it has abundant water, but in fact less than 1 percent is available for human use. The rest is either salt water found in oceans, fresh water frozen in the polar ice caps, or too inaccessible for practical usage. While population and demand on freshwater resources are increasing, supply will always remain constant. And although it's true that the water cycle continuously returns water to Earth, it is not always returned to the same place, or in the same quantity and quality.
