Meiosis is a key process in the sexual life cycle of eukaryotes and is essential for the survival of eukaryotic organisms. In the process of meiosis, crossing over and
independent assortment are events that occur that allow the genes on the
homologous chromosomes to be randomized. These events result in greater genetic
variation than asexual reproduction or mitosis because it
Is more common in higher order species.
O
Results in a greater number of offspring.
Is a lengthy process full of errors.
d
Results in different genetic combinations.

The movement of tectonic plates in two different locations is shown below: two blocks labeled location a and location b are shown. at location a the top layer of the block shows two horizontal arrows pointing towards each other. small dunes are shown in the middle between the two arrows. the block labeled b has a vertical line in the middle. on the left of the line there is an arrow pointing down. on the right of the vertical line there is an arrow pointing up which statement is most likely true? subduction may occur in both locations. earthquakes may occur in both locations. subduction may occur in location a only and a volcanic eruption may occur in location b only. an earthquake may occur in location a only and a volcanic eruption may occur in location b only.
