Cells with cell chemicals and genetic material having no defined organelles and are all enclosed within a cell wall are called prokaryotes. Organisms in this group are small in size and are mainly bacteria. Ribosomes in these small cells are also small and ‘free floating’. DNA in prokaryotic cells is in the form of a circular strand and not as a chromosome.

3. The solution to teen smoking- https://www.mayoclinic.org/healthy-lifestyle/tween-and-teen-health/in-depth/teen-smoking/art-20047069
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.
