A cat's hind‑limb reflex arc has a length of 0.20 m and the total response time measured is 0.040 s. A rabbit's hind‑limb reflex arc is 0.12 m long with a response time of 0.030 s. (a) Calculate the nerve impulse conduction velocity for each animal (in \(\text{m}\cdot\text{s}^{-1}\)). (b) Which animal has the faster conduction velocity? (c) State the ratio of the cat's velocity to the rabbit's velocity, expressed as a simplified fraction.

Answer Options

A. cat: 4 m·s^{-1}, rabbit: 3 m·s^{-1}, cat faster, ratio 4\/3
B. cat: 5 m·s^{-1}, rabbit: 6 m·s^{-1}, rabbit faster, ratio 5\/6
C. cat: 6 m·s^{-1}, rabbit: 4 m·s^{-1}, cat faster, ratio 3\/2
Correct Answer D. cat: 5 m·s^{-1}, rabbit: 4 m·s^{-1}, cat faster, ratio 5/4
Correct Answer
D
Correct Option:
cat: 5 m·s^{-1}, rabbit: 4 m·s^{-1}, cat faster, ratio 5/4
