Comets

Explanation: Comets are made mostly up of rock. A comet is like a giant dirty snowball, the size of a town or city. It is made up of ice, dust, and small pieces of rock. As a comet gets closer to the sun, it starts to melt and it becomes surrounded by a lot of gas and dust.

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 : )

do you have a picture?
