C. The brain sends messages to the spinal cord
The correct terms to fill in the blanks are lateral ventricles and venous sinus blood. Cerebrospinal fluid (CSF) is formed by lateral ventricles and reabsorbed through arachnoid granulations into the venous sinus blood. The CSF is a fluid that is clear and colorless found in the spinal cord and in the brain, generally the central nervous system. The CSF functions as a buffer or a shock absorber for the brain. It provides basic mechanical protection for the brain. Also, it helps in the circulation of nutrients and the chemicals that are filtered and aids in the elimination of waste products.

Answer:
RER is involved in protein synthesis, folding, transport and modification.
Explanation:
The Endoplasmic Reticulum is an organnelle found in eukaryotic cells. They are of two types; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum, so named based on the appearance of their surface. The Rough Endoplasmic Reticulum (RER) obtains it rough appearance from the membrane bound ribosomes attached to it.
Due to the ribosomes that attach to them during protein synthesis, their function is very much associated with protein synthesis. They are primarily involved in protein production, which would either remain in their lumen for further modification/processing called Glycosylation (adding sugar to proteins to form glycoproteins) or be transported through secretory vesicles to the Golgi apparatus. They also fold this proteins in their inner membrane structure called cisternae.
Mycoplasma gallicepticum, a parasitic bacterium which lives in the primate bladder, waste disposal organs, genital, and respiratory tracts, is thought to be the smallest known organism capable of independent growth and reproduction. The cell in the work is known as mycoplasma. Its diameter is 0.0001 mm.
