Many experts believe that if we continue to use fossil fuels at the rate we are now, we will run out of this natural resource by the middle to end of the twenty-first century. fossils fuels, the remains of once living plants and animals, primarily recycle the element and when burned, these fuels add the element back into our atmosphere.

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 : )
