In metazoa, which one of the following is responsible for locomotion and movement of organs?

• A. Nervous tissues
• B. Epithelial tissues
• C. Connective tissues
• D. Muscular tissues

Answer 1

The correct option is D Muscular tissues

Metazoa is the group, that are multicellular animals having cells differentiated into tissues and organs and usually a digestive cavity and nervous system (also called Animalia).
In metazoa, the muscular system is responsible for the movement of the body and is responsible for locomotion. Attached to the bones of the skeletal system are about 700 muscles. Muscle tissue is also found inside of the heart, digestive organs and blood vessels, and responsible for the movements of the organs.
