(12g)/(75.398cm^3)
=0.159 g/cm^3
answer would be = 0.16 g/cm^3
The difference between the "Question" and the "Hypothesis" is that a hypothesis is what you believe is the answer to the question based off of limited evidence while the question is just a regular question e.x. (for question) "Why is the water moving to the south?"
then using whatever evidence they will have they would do a hypothesis e.x. (for hypothesis) I believe the water is moving south due to the wind coming down from the north... or due to a current.
Explanation:
As lineages invade different niches and become isolated from one another, they split, regenerating some of the diversity that was wiped out by the mass extinction. The upshot of all these processes is that mass extinctions tend to be followed by periods of rapid diversification and adaptive radiation.
