Does nonmetal activity tend to decrease or increase as one goes down group 17?
It's decrease because florine has the most activity.
Is decrease GI motility and secretion has a cholinergic effect?
Acetylcholine is a neurotransmitter in the GI tract (among other places). An increase in acetylcholine activity (also known as cholinergic activity) results in an increase in GI motility and secretion, not a decrease.
What are two types of feedback mechanisms found in living organisms?
positive feedback - increase activity negative feedback - decrease activity

Is decrease GI motility and secretion has a cholinergic effect?
Acetylcholine is a neurotransmitter in the GI tract (among other places). An increase in acetylcholine activity (also known as cholinergic activity) results in an increase in GI motility and secretion, not a decrease.
