- A joint, sometimes referred to as an articulation, is where two or more bones come together. The names of two bones are included in each articulation.
- Immobile joints are ones that do not permit movement at the joint sites .These joints don't have a joint cavity; instead, dense fibrous connective tissue, typically collagen, holds the bones physically together.
- A synovial membrane-lined joint capsule that produces synovial fluid surrounds and protects the two of them.
- Specialized joints known as cartilaginous joints can be identified by their structural characteristics.
- In fibrous joints, white connective tissue fibres that travel from one articulating portion to the next separate the articulating parts.

Answer:
Diffusion is powerful over a particular distance and bounds the size that a character cellular can gain.
Explanation: If cellular is an unmarried-celled microorganism, consisting of an amoeba, it is able to satisfy all of its nutrient and waste needs via diffusion. If the mobile is too massive, then diffusion is useless at finishing all of these responsibilities.
