4. What is an example of positive feedback?

Biology
1 answer:
Shtirlitz [24]3 years ago
4 0

Answer:

C

Explanation:

It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.

Compared to unmyelinated axons, myelinated axons?
Furkat [3]

Answer:

A. Conduct impulses faster.

Explanation:

Myelinated axons are called that way due to the myelin sheath that surrounds them. Myelin has an insulation property so electrical impulses cannot travel through it, except on certain sites called Nodes of Ranvier. In order for electrical impulses to be conducted on myelinated axons they must "jump" from one Node of Ranvier to the next, and thus conduction is faster. This is called saltatory conduction.
