Expert Solution & Answer
Answer to Problem 24A
Correct answer:
Option (B).
Explanation of Solution
Explanation/justification for the correct answer:
Option (B) radula- feeding. Radula is a muscular structure, similar to the tongue and it helps in feeding. Hence, the correct answer is option (B).
Explanation for incorrect answer:
Option (A) shell-circulation. The shell helps in the protection of the organism. Hence, it is an incorrect answer.
Option (C) jet propelled swimming- bivalves. Jet propelled awing is observed in squids. Hence, it is an incorrect answer.
Option (D) open circulatory system-octopus. The octopus have a closed circulatory system. Hence, it is an incorrect answer.
