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.
Answer: C
The substance that must come through the cell membrane for the cell to live is nutrients. Cells would die if they did not get nutrients. Nutrients are what keeps the cell running.
<span>The correct answer is D. Micromanipulation allows interaction with precision. This is done under a microscope. With micromanipulation, in-vitro fertilization has come true, and is helping thousands of parents to become parents.</span><span />
