Because biological systems are generally held at constant temperature and pressure, it is possible to predict the direction of a chemical reaction by measuring which of the following? a. ATP concentration
b. Enthalpy

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!

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.
