Answer 1

Frogs are adapted for jumping by having long, strong back legs with additional joints and a short backbone with a large hip bone, allowing them to jump long distances efficiently.

Step-by-step explanation:

The adaptation of a frog's skeletal system that allows for easier jumping is its long, strong back legs with additional joints and a short backbone (spine) featuring a large hip bone. Frogs have evolved these features to be excellent jumpers, capable of leaping distances up to 20 times their own body length. Their appendicular skeleton differs from aquatic animals, and their limb placement under the body allows for efficient overland movement, mimicking a pendulum-like stride that is well adapted for jumping and landing.

Frogs' hind limbs are specifically adapted for jumping. During the metamorphosis process, the hind legs develop considerably more than the front legs, ultimately contributing to the powerful jumping ability seen in adult frogs. Moreover, the muscles and bones of the hind limbs are structured to store and release energy effectively during a jump. This is further facilitated by a short vertebral column, consisting of fewer vertebrae, which allows for greater flexibility and power during the jumping motion.
