How does this affect the change?

B. It sped up evolutionary change by increasing genetic variation.

Explanation:

Evolution works when organisms with genes that are better suited to the environment pass on their genes to future generations.

Sexual reproduction sped up this process because it allowed for genetic variation as genes from the two mates would be passed on the next generation instead of one organism as had been the case with asexual production.

With genes from both mates mixing up and going into the next generation, more genetic variations were produced which allowed for the organisms to better adapt to the environment.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
