Answer 1

Answer is:

1) mammals - mammary glands.

2) Rotifera - cilia in circular arrangement.

3) Cnidaria - nematocyst.

4) Mollusca - radula.

Mollusca is a large phylum of invertebrate animals.

Cnidaria are mostly marine animals.

Rotifera are phylum of microscopic pseudocoelomate animals.

Answer 2

Answer:

• Mammals - mammary glands
• Rotifera - cilia in circular arrangement
• Cnidaria- nematocyst
• Mollusca- radula

Explanation:

• Mammals are the those animals whose body is covered with hairs, give birth to young ones and have mammary glands to feed young ones.
• The rotifers are multicellular, free swimming planktons. The body of the rotifers divided into a head, a trunk and the foot. The head contains a rotating, wheel-like structure which is covered with cilia.
• Members of the phylum cnidaria contains nematocysts which are the protective organs. Nematocysts are stinging structures are composed of special cells called cnidocytes.
• Mollusks are soft bodied animals whose body is divided into a head, a visceral mass and ventral foot. Radula is tiny teeth used for scraping food particles off a surface and drawing them into the mouth.
