Determine whether the graph of the equation is symmetric with respect to the x-axis, y-axis, origin, or none of these. You must show your work algebraically for full credit.x = y2 + 6

Determine whether the graph of the equation is symmetric with respect to the x-axis, y-axis, origin, or none of these. You must show all of your work algebraically on your own paper for full credit. y – 6 = x2

A point mutation occurs in hemoglobin gene in sickle cell anemia.

Chernobyl Nuclear Power station explosion is an example of accidental exposure to mutagens.

A plant with purple flowers is allowed to self-pollinate. Generation after generation, it produces purple flowers. This is an example of hybridization.

Increasing environmental levels of mutagen is likely to lead to increasing frequency of deleterious alleles.
