What did the Fish and Wildlife Service (FWS) do to bring back black-footed ferrets from extinction? The FWS moved mating pairs from the Wyoming population to over 8 western states and Mexico to begin new colonies.

The captive breeding program was implemented too late to save the black-footed ferret.

The FWS monitored a Wyoming population and captured enough individuals to start new populations.

The FWS use a captive breeding program to start populations in 8 states.

Explanation:

I just took a quiz and got this answer right.

D) 20.0 atm

Explanation:

To solve this problem, we can apply Boyle's law, which states that:

"For a constant mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to the volume of the gas".

Mathematically:

where

p is the gas pressure

V is the volume of the gas

The equation can also be rewritten as

where in this problem:

is the initial pressure of the gas

is the initial volume of the gas

is the final volume of the gas

Solving for p2, we find the final pressure of the gas:
