This is a curved, pointed appendage, found at the end of a toe or finger in most mammals, birds, and some reptiles. It is often used to refer to the hooked structures found on arthropods.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

a and c are the answeres

the answer is a) cell division.

hope this !
