The pia mater is the only meninges to continue into a brain sulcus after the brain surface.
What are meninges?
The skull and spinal cord are encased in three tiers of membranes called meninges. These are:
- The pia mater is the fragile inner layer.
- The arachnoid, a fluid-filled web-like structure that forms the brain's intermediate layer, is what gives the brain its cushioning effect.
- The dura mater is the name of the hard outer layer.
The term for the three gaps between the meninges-
- The gaps between the layers of the meninges are known as meningeal spaces.
- Epidural, subdural, and subarachnoid are the three clinically important meningeal compartments.
The function of meninges:
- It acts as a shock absorber, the CNS (central nervous system) will shield our brain from trauma harm, such as a knock to the head.
- They secure our central nervous system and prevent our brain from shifting inside our skull.
Therefore the correct solution is an option (A),i.e., pia mater.
The complete question is:
The only one of the meninges that follows the brain surface into a cerebral sulcus is the
a. pia mater.
b. alma mater.
c. dura mater.
d. arachnoid mater.

Answer:
option B
Explanation:
igneous rocks are the rocks which are formed by the cooling of molten magma cooling can be on the surface or below the earth surface.
sedimentary surface is the rocks which are formed by the weathering or some chemical action upon the rock due to the passage of time.
metamorphic rocks are those rocks which are formed due to the high pressure and temperature acted on the rocks.
so, the best answer will be sedimentary rock
hence, the correct answer is option B
A spike in the popularity of Snapper fish in American restaurants causing a sharp increase in Snapper fishing will result in the number of Nassau grouper to increase.
<h3>What is the relationship between Snapper fish and Nassau groupers?</h3>
The Snapper fish and Nassau groupers are two types of fishes which are fished for their delicious meat.
Both are found in fish markets where they are important delicacies especially in grilled fish.
An increase in the population of one fish will result in more fishing and hence an increase in the population of the other fish.
Therefore, a spike in the popularity of Snapper fish in American restaurants causing a sharp increase in Snapper fishing will result in the number of Nassau grouper to increase.
In conclusion, the popularity of one fish over the other will affect the population of the other fish.
