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.

The question is incomplete as itt does not have the options which are:
A) The folds in the membranes are a physical barrier for compounds that attempt to enter the organelle.
B) The folds allow for more surface area for the chemical reactions that occur across the inner membranes.
C) The folds allow these organelles to interact more efficiently with Golgi bodies.
D) The folds cause a necessary change in the organelles' internal pH.
Answer:
B) The folds allow for more surface area for the chemical reactions that occur across the inner membranes.
Explanation:
The mitochondria and chloroplast are double-membrane organelle that contains the outer and inner layer.
The outer layer is usually smooth of both the chloroplast and mitochondria but the inner membrane is not regular but folded.
The folding is an adaptive feature of these organelle to increase the surface area. The increased surface area allows the more ATPase in the inner membrane, therefore, increases the amount of ATP generated.
Thus, Option-B is correct.
Overtillage can increase the rate of humus decomposition
Answer:
It should be noted the options for the question are not complete. But the answer is,
As capillaries become engorged, the upper respiratory tract is affected by the subsequent edema and hyperemia, which causes these conditions, seen commonly during pregnancy.
Explanation:
Nasal congestion is a situation where the nasal passage become blocked. This is due to the swollen of the tiny blood vessel lining the nose. This is because the blood vessels have been inflamed.
There are many methods which can be adopted to relieve it.Some of them are
* Drinking lots of fluid
* Breathe in steam from a container with warm water
* using vaporizer
* Avoiding chlorinated pools.
Epistaxis is known to be bleeding from the nose. This can be caused by been exposed to dry air, which can cause the damage of the tiny blood vessels.
One of the methods that can be use as treatment is cauterization. This is the use of chemical swabs to cautirize the nose , and this eventually seals the damaged blood vessels.
This is an emergency situation in a pregnant woman because, it may may reduce the amount of oxygen required by the unborn baby.
Answer:
A
Explanation:
The Sun, Moon, and planets appear to move across the sky much like the stars. Because of the Earth's rotation, everything in the sky seems to move together, turning once around us every 24 hours. ... Likewise, every point on the celestial equator is exactly overhead from some point on the Earth's equator.The Sun, Moon, and planets appear to move across the sky much like the stars. Because of the Earth's rotation, everything in the sky seems to move together, turning once around us every 24 hours.
