Question

what happens when the endocrine system malfunctions? the brain picks up those functions and proceeds as normal. the organs become isolated and lose the ability to coordinate effectively. the heart picks up those functions and proceeds as normal.

Explanation:

The endocrine system coordinates organ functions via hormones. If it malfunctions, organs relying on its hormonal signals lose coordination. The brain (not for endocrine function backup) and heart (pumps blood, not endocrine) don't take over endocrine roles. So the correct option is the one about organs becoming isolated and losing coordination.

Answer:

The option: "The organs become isolated and lose the ability to coordinate effectively."
