THIS IS IN MY TEST How would you compare the mass of an inflated balloon to the mass of a deflated balloon?

The mass of an inflated balloon is higher because it contains air. Even when inflated with helium, it has a higher mass because helium has mass. However, an inflated balloon has a much lower density than a deflated balloon.

fir trees are found in areas with cooler climates. fir trees have needles for leaves and remain green year-round.

i am pretty sure it is d.
