Now suppose you were using plutonium 239 in a nuclear fission reactor. how long would it take 20 g of radioactive plutonium 239 decay down to a safe 2.5 g? show work.

It will take years.

Explanation:

Plutonium 239 has a half life of years.

We know, for radioactive decay, that the quantity of radioactive material N at time t can be obtained with the equation

where is the initial quantity of radioactive material and is the half life of the material.

Taking the values of our problem:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

this would be about 43%
