Question

In which of the following animals are bones not present?

• A. Earthworm
• B. Snail
• C. Cockroach
• D. All of the above

Answer 1

The correct option is D All of the above

Earthworms do not have a backbone. They fall under the category of invertebrates. They do not have bones, legs, eyes, or teeth. A cockroach has six legs, three body segments, and no bones. It has an exoskeleton in place of a skeleton. The endoskeleton is hard and shell-like and covers its body. Snails have no bones, or rings or joints in their bodies. Hence, the correct answer is D.
