Answer:
The cell of amoeba is shaped differently than the classical round or boxy shape seen in textbooks.
Explanation:
Amoebas are unicellular organisms i.e consisting of a single cell. The amoebic cell can change its shape due to pseudopods. Pseudopods are structures in the amoeba that allow movement of the cell as well as help the amoeba to trap food by engulfing the particles. The species of amoeba are differentiated based on pseudopods. Amoeba also possess contractile vacuoles that helps it to get rid of the extra water.
Most of the joints in the appendicular skeleton are synovial joints.
So, the correct option is (c).
- 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.
