Statement : Locomotory structures need not be different from those affecting other types of movements.
Which of the following condition correctly defines the above statement?  

Options

A. Humans use limbs for changes in body postures and locomotion as well.
B. Hydra can use its tentacles for capturing of its prey and also use them for locomotion
C. In Paramoecium, cilia helps in the movement of food through cytophaxynx and in locomotion as wel I.
D. All of the above

Answer

D

Explanation

Locomotory structures need not be different from those affecting other types of movements. For example, in Paramoecium, cilia helps in the movement of food through cytopharynx and in locomotion as well.
.Hydra can use its tentacles for capturing its prey and also use them for locomotion. We use limbs for changes in body postures and locomotion as well.
.The above observations suggest that movement and locomotion cannot be studied separately
