Which hormone regulates the growth of bone muscle and other body tissues?

Somatotropin

Somatotropin is a polypeptide growth hormone that regulates the growth of bone, muscle, and other body tissues. Somatotropin is secreted by somatotropic cells within the anterior lobe of the pituitary gland. Somatotropin is important in human development as it stimulates growth, cell regenerations and reproduction in humans and other animals. The levels of somatotrophin rise increasingly during childhood and also occur at its peak in puberty.

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.
