When they occur, greenhouse gases a0, because they are long lasting and do not just disappear into the air.

Greenhouse gases are REALLY bad for the environment and one of the major cause of global warming. Greehouse gases can stay lasting in the air for 20 to 200 years.

When they occur, greenhouse gases are "cumulative", because they are long lasting and do not just disappear into the air.

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 : )

the answer is c on e2020, bud.
