Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis.

Answer:
In the absence of joint spaces (cavities) and bones fused together, body movements would be null or reduced.
Explanation:
The joints are the spaces where two bones meet, with cartilaginous tissue - articular cartilage and ligaments - to allow elasticity and body movements.
The articular cavities are spaces where bone union occurs through ligaments, surrounded by an articular capsule and upholstered inside by a membrane that produces liquid, the membrane and synovial fluid, respectively. These joints are usually found in the mobile body segments.
<em><u>If the joint cavities did not exist, and the joints occurred between bone and bone, body mobility would not be possible</u></em>. In the case of the skull bones, they do not have joint space, since their function is the protection of the organs of the central nervous system, not movement.

I think the correct answer from the choices listed above is option C/ One reason that a product does not always form is due to unfavorable geometry of the reactants involved. When the geometry is not good for substances to react then no reaction can occur although there is enough energy present.
