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.
Answer:
the triceps brachii of the posterior arm is an agonist that causes forearm,this muscle helps depress and protract (pull anteriorly) the scapula and rhomboid minor also works as a synergist to the Pectoralis major in flexing and adducting the arm,the serratus anterior differs from the subclavius and pectoralis minor in that. Functional demands have resulted in the evolution of individual muscles from the basal unit formed by the serratus anterior. In primitive life forms, the main function of the axioscapular group is to control the movements of the vertebral border of the scapula: fibers concerned with the dorsal movement of scapula evolved into the rhomboids, those with ventral motion into serratus anterior, and those with cranial movements into levator scapulae. The evolution of the serratus anterior itself has resulted in (1) grouping of its distal and proximal fibers, (2) size reduction of its intermediate fibers, and (3) the insertion of its dominant superior and inferior parts onto the superior and inferior angles of the scapula

The two types would be thermal energy and light radiation, which is usually present in most ecosystems since the sun gives off both of them.
