We could do thing with our hands without having to use some of our energy in getting up to try to balance on our two rear legs.
Active transport requires energy. Passive transport does not require energy. In case you did not know active transport is the movement of ions or molecules across a cellular membrane from a lower to a higher concentration.

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.
