What is the signal speed if the thickness of the myelin sheath is halved but no other changes are made to the axon?

Biology
1 answer:
blagie [28]1 year ago
6 0

Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.so the signal speed might slow down as it got halved

Myelin is the insulating layer, or sheath that forms around the nerves, including those in the brain and in the spinal cord. It is made up of some  protein and fatty substances. This myelin sheath is allows electrical impulses to the transmit quickly and efficiently along with the nerve cells. If the myelin is damaged, these impulses slow down.

Myelin is repaired or replaced by the special cells in the brain called as oligodendrocytes. These cells are made from special type of stem cell that found in the brain, called as oligodendrocyte precursor cells (OPCs).

             variable = c
             constant = 35 & 23.50
In part B: 
           savings = 20 (3) +23.5+ 35+35+35 +35 +35 +35+35+35+35+35+35+35
           savings = $ 503.5

Enzymatic breakdown of which of the following compounds doesn’t begin until it reaches the stomach?
ahrayia [7]

Answer:

B. Proteins

Explanation:

Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).

Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.
