1. All of the DNA being copied into each cell
2. Random division of DNA
3. Mitosis
4. Meiosis

The process that increases genetic variation is:

4. Meiosis

Explanation:

The reasons for this answer are two. First of all genetic variation can be produced by mutation, in other words, by combination, and fertilization. This is the origin of the second reason. when these phenomenons involve homologous chromosomes they are under a meiosis phenomenon. Because meiosis is the only event that can happen under these conditions

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
