a. muscle tissue
b. nervous tissue
c. epithelial tissue

a. ball-and-socket joints
b.

Explanation:

A mineral is a solid chemical compound, which has a inorganic composition, because not always they have carbon atoms in their structures. On the other hand, vitamins have carbon-bases structures.

Muscles can be classified as voluntary or involuntary muscles. Voluntary muscles perform locomotion, tongue, pharynx and diaphragm movements. Involuntary muscles perform actions like respiratory, alimentary or urogenital movements.

Ball and socket joints are spheroid joints which can move in many directions due to their spheric shape, refer to the image attached. This joints are needed in specific areas like shoulders or hips, because they allow a multi directional movement, which is needed to move arms and legs free.
