1. by examining the fin of a primitive fish, scientists
have found similarities in bone structure to that of
modern day reptiles, birds, and mammals. what
type of evidence does this describe?

multiply it by 5 in order for you to understand i cant give an exact answer.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
