<h3>What is a hormone?</h3>
A hormone is a chemical messenger that is released into the bloodstream in order to carry out particular physiological functions.
The human growth hormone is a hormone required during the growth that induces cell division during specific stages of human development.
The human growth hormone is secreted by specialized cells present in the anterior pituitary gland.
The expression level of the gene encoding the human growth hormone can be used in clinical settings in order to determine the presence of abnormal growth during embryo development.
In conclusion, the decrease of human growth hormone is associated with the loss of muscle tissue as we age.

- Touch time: it has to be verified that the manufacturer's data to make sure the organism stays in contact for the specified amount of time. Considering that solid materials like cells and tissue granules are difficult for disinfectants to penetrate, autoclaving would be a more effective way to inactivate.
Therefore the correct choice is an option (A).
