The answer is letter C.) <span>Affected father and carrier mother
"Affected" refers to the person having the recessive gene of the color blindness, while "carrier" means the person carries two of the recessive genes of the trait. For the couple to produce a 1:1 ratio of normal to color-blind offspring, they would need to have the combination of affected father and carrier mother.

A. a tree
you can first eliminate B. and C. to make it easier to choose an answer. then you can eliminate a generator because it would turn mechanical energy into electrical energy. a tree uses photosynthesis to convert light energy into chemical energy, using the sun as a source for the light energy and turning it into food (chemical energy)
