The fatty substance that insulates and protects the axon is myelin sheath. That is option D.
<h3>The nerve cells (neuron)</h3>
The nervous system is made up of nerve cells that helps to send and receive signals that are interpreted by the brain.
The parts of the nerve cell include the following:
The axon is part of the nerve cell that transmits electrical signals. it is surrounded by myelin sheath.
The myelin sheath is a fatty layer that insulates the axon and helps it transmit signals over long distances.
Therefore, the fatty substance that insulates and protects the axon is myelin sheath.

Question 1) Photesphere
Question 2) core
Question 3) The suns gravity keeps them in place
Question 4) True
I'm not 100% about question 1 it's either photesphere or core, but I think Photesphere is correct
Predators have to eat. If things are good in an eco-system then the prey is eating good which means the predators can eat good also. Starvation means that things in the eco-system are going bad. Also, It helps the earth maintain its balance. If too much of any aspect of the system is removed it throws the whole thing off balance. too many herbivores will eat too much vegetation.
Answer:
c. Would have deviated from the 9:3:3:1 phenotypic ratio
Explanation:
<em>If two genes are linked together on the same chromosome, the phenotype of the F2 generation would have deviated from 9:3:3:1.</em>
Two genes whose loci are close on the same chromosome are said to be linked. Linked genes have higher frequency of recombination than genes that are not linked.
<u>Hence, while genes that are not linked assort independently to produce 9:3:3:1 phenotypic ratio at F2, linked genes do not assort independently and the higher frequency of recombination ensures that they standard phenotypic ratio is deviated from.</u>
The correct option is c.
