Answer: b. The radius forms the point of the elbow
c. The radius articulates to the wrist closest to the thumb
Explanation:
Ulna and radius are the two bones of the forearm. These bones articulates with the humerus and carpels of the hand.
b. The radius forms the point of the elbow: The elbow joint is the hinge joint that forms between the proximal ends of the radius and ulna in the forearm and distal ends of the humerus. The radius forms a pointed end.
c. The radius articulates to the wrist closest to the thumb: The wrist forms a complex joint. It forms a transition between the hand and the forearm. The radial deviation in the wrist forms the basis for the movement of the tilting of the wrist joint towards the thumb.
The temperature at tropic region is warmer than the polar temperatures due to angle of the sun.
The tropics which is located near the equator are hotter than the arctic region i.e. north and south poles because the sunlight falls directly on the tropic regions at 90 degrees while on the other hand, the sunlight falls on the poles not directly and form angle lower than 90 degrees.
The amount of solar energy in a given area is greater at the equator and tropic regions than in an equal area at the poles so that's why the temperature at tropic region is warmer than the polar temperatures.
