If 30% of the bases in a particular DNA molecule are guanine (G), calculate the percentage of the bases would be thymine (T). Explain your reasoning.

20%

Explanation:

Because if 30% is G then 30% is C cytosine (because G and C bond together in the DNA) which added together gives 60%. Which subtracted from 100% is 40% that is divided between 2 that gives 20% to represent the other two bases T and A.

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.
