A chemical change is a change in which the composition of the matter is changed at the molecular level, most chemical changes are not easily irreversible, for example, an egg being cooked, the egg changes from its liquid like state to a solid, and it is not possible to revert it back to its original change. The egg itself is changed in this case.
A physical change on the other hand however, is only changing the substance of a matter, not its composition, this is usually easily reversible.

Sorry for the long explanation,
Hope this helps!

Option A
Target organs regulate the pituitary through feedback loops. Most often, this takes the form of negative feedback inhibition.
<u>Explanation:</u>
Feedback inhibition is a cellular regulatory mechanism in which an enzyme’s action is frustrated by the enzyme’s terminal product. This method enables cells to control how much of an enzyme’s terminal product is created. An outstanding case of a negative feedback loop is detected in the regulator of thyroid hormone secretion.
To manage the discharge of chemical signals in the hypothalamus, pituitary glands Negative Feedback utilized widely. Negative feedback transpires when a product supplies back to reduce its creation. When the output of a way that constitutes restrains inputs to that way is recognized as Negative feedback
