<h2>The Forearm</h2>
Explanation:
The proximal end of the radius illustrates the relationship of form and function. The cup-like surface of the radial head articulates with the rounded shape of the capitulum. This forms a joint that allows for movement of elbows and forearms.
Radius and ulna are the two bones of the forearm. Their proximal ends articulate and fit into the cup like end of the humerus. This forms a synovial joint called the elbow joint. The movement of this joint allows the forearms to supinate and pronate.
Continental not really sure but a good guess
The answer to the question is depressions.

I believe it is "arctic predators or winter hunters" they all hunt in the snow and all of them are predator which mean they eat all different types of small animals like mice.
