The correct statements are:

Meiosis is a type of cell division in which one cell divides to form four daughter cells, each carrying exactly half the chromosomal number of the parent cell.

It is mainly used in the formation of gametes in organisms which reproduce sexually.

The fusion of gametes restores the original chromosome number. Thus, it helps in maintaining the chromosome number throughout generations. In absence of meiosis, the chromosome number would have doubled after each fertilization event or after each generation.

In addition, events like random segregation of chromosomes and crossing over cause genetic recombination as well as genetic variation.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
