Answer:
c) degree of myelination of the axon
Explanation:
Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.
Factors that determines the rate of conduction velocity are:
- axon diameter-larger diameter axons have a higher conduction velocity
- sheeth-a myelin sheath increases the rate of impulse propagatio
Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.
Mitocondria, the power house of a cell.
This is going to be false. Because of the makeup of aluminum, it cannot be transparent.
Based on research, microbes have been recently associated with the following four diseases that were once considered noninfectious:
- gastric ulcers
- multiple sclerosis
- cancer
- diabetes
<h3>What are microbes?</h3>
Microbes refers to microscopic organisms, that is organisms which can not be seen with the ordinary eye but with the aid of a microscope.
Microbes consists of the following organisms:
- bacteria
- fungi
- protozoa
- viruses
Some microbes are not harmful while many other microbes are harmful and are known to be the causative organisms for many diseases.
The diseases that are caused by microbes can be passed from one person to another and are known as infectious diseases.
However, recent research have linked microbes to some diseases such as gastric ulcer, multiple sclerosis, cancer, and diabetes which were once considered non-infectious.
Example are given below;
- gastric ulcer caused by <em>Helicobacter pylori</em>
- Multiple sclerosis caused by Epstein-Barr virus
- Cancer caused by human papilloma viruses, hepatitis B and C viruses
- Diabetes caused by E. coli and Candida spp.
In conclusion, microbes cause infectious diseases.
