Answer:
2 moles of F
Explanation:
for every molecule of CaF2, without the two atoms of F, CaF2 cannot be formed.
Now we multiply both CaF2 and F by 6.02 X 10^23 to convert CaF2 and F to moles, it will be the same ratio since we multiplied both by the same number

Answer:
The correct answer is C) arachnoid mater.
Explanation:
Arachnoid mater, along with pia mater and dura mater, form the <u>meninges</u>, a very thick membrane that protects the brain and the spinal cord. The arachnoid mater is in the middle of the other two layers and it is very important since it holds the <u>cerebrospinal fluid (CSF)</u> in its interior. Arachnoid mater has finger-like projections that enter the dural venous sinuses and are called <u>arachnoid villi</u>. These villi are responsible for the diffusion of CSF into the blood.
They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus and lysosomes. Peroxisomes as well.
