Which of the following adaptations do rabbits have for jumping?

Rabbits have specialized adaptations that enable them to excel at jumping, and one of these adaptations includes shock absorbers in their feet. The feet of rabbits are designed with a structure that helps to cushion the impact when they land after a jump. This adaptation is crucial because it allows them to absorb the shock from high jumps, reducing the risk of injury and improving their agility and speed. By effectively dealing with the stresses of jumping, rabbits can quickly flee from predators, making this adaptation an essential survival trait.

The other adaptations mentioned do not play a direct role in their jumping ability. For instance, compact neck vertebrae or elongated skulls are more related to head stability or movement, while thinner bones might impact their overall skeletal strength, which is not beneficial for the force exerted during jumping. The presence of shock absorbers, therefore, is key to understanding how rabbits efficiently manage the physical demands of their powerful leaps.
