Answer 1

The statement that describes an interaction between the endocrine system and the skeletal system is:

OA. When PTH increases, the calcium level in the blood rises.

The parathyroid hormone (PTH) is produced by the endocrine system and plays a role in regulating calcium levels in the body, which is important for the skeletal system among other functions.
