Answer:

Answer:
Eukaryotic cells
Explanation:
There are two main types of cells among living organisms:
- Eukaryotic cell (plants, animals, fungi) which is more compound, conntains nucleus with genetic material in it, membrane-bound organelles (mitochondria, Golgi apparatus, lysosomes etc). Because of their complex structure, the process within such cells are often more comlex then those in prokaryotes. Eukaryotic organisms are usually multicellular
- Prokaryotic cell is simple cell found in Archea and Bacteria kingdom. It doesn't have nucleus neither membrane-bound organelles. Genetic material of these cell is located within the cytoplasm together with proteins and metabolites. First living cell was prokaryotic cell. Organisms that are prokaryotic are usually unicellular.

C. ACTING AS A SHOCK ABSORBER FOR THE BRAIN AND SPINAL CORD</h2>
Explanation:
Meninges are tissues that provide protection, support and also serve metabolic roles for the nervous system. The cerebrospinal fluid is the fluid of the central nervous system and serves as protection, gives buoyancy to the brain, assists in excretion of waste products of metabolism from the brain.
These meninges are of three membranes; the dura mater which is the outer membrane; the pia mater which is rich in blood vessels and the arachnoid mater which keeps the brain in the cerebrospinal fluid. The meninges, along with the cerbrospinal fluid serves to cushion the brain and spinal cord preventing shocks. The pia mater layer of the meninges provides for the delivering of oxygen directly into the CNS and protects the brain from infections through the action of the leucocytes in the blood.
