The answer is c as the population had failed to survive
I found this radiography online, i hope it's the same:
1- <span>Spinous process
2- Atlas ( it's the first vertebra)
3- Axis </span><span>( it's the second vertebra)
4- Transverse process
5- </span><span><span>Intervertebral disc</span> (present between vertebras)
6- body of the vertebra
the occipital bone is a reference that it's the posterior side, while the mandibule indicates it's anterior.

<h3><u>Answer;</u></h3>
The permeability of the membrane
<h3><u>Explanation</u>;</h3>
- The fluidity and the permeability of cell membrane must be maintained within a certain range for the cell to function properly.
- The permeability of cell membrane depends on a number of factors, among them is the degree of saturation of fatty acids tails making up phospholipids.
- Phospholipid tails can be saturated or unsaturated. Saturated tails have no double bonds and as a result have straight, unkinked tails, while unsaturated tails have double bonds and, as a result, have crooked, kinked tails.
- Interactions between tails are maximized in the case of saturated tails, thus decreasing membrane fluidity and permeability, while unsaturated tails increases membrane fluidity.
