Answers
Answer:
Explanation:
1)In zoology, a tentacle is a flexible, mobile, elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work mainly like muscular hydrostats.
2)freshwaterContractile vacuole, regulatory organelle, usually spherical, found in freshwater protozoa and lower metazoans, such as sponges and hydras, that collects excess fluid from the protoplasm and periodically empties it into the surrounding medium.
3)Cartilage is a resilient and smooth elastic tissue, a rubber-like padding that covers and protects the ends of long bones at the joints and nerves, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components.
Location of tentacles :- grows near the mouth of an animal.
Location of contractile :- present in heart.
Location of vacuole :- Cytoplasm of a cell
Location of cartilage :- at the ends of the ribs, and in the nose, larynx, trachea, and bronchi.
