Sternocleidomastoid and the Scalenes are Synergists, which mean that they work together to provide the same movements (flexion, rotation and lateral flexion of the head and neck)An Antagonist is a muscle that does the opposite movements. In this case, Antagonists of the Scalenes would be your posterior neck muscles, such as:Upper TrapeziusSplenius CapitusSplenius CervicisSemispinalis Capitis, etc
There are a lot of different ways to categorize exercises or movements so there could be more than on correct answer to this question. Commonly, however, push-ups would be classified as a closed-chain horizontal pressing exercise. Sit-ups are normally just considered an abdominal flexion exercise. To be technical, they would be classified as a flexion/extension of the trunk, or spine, in the sagittal plane.
The Pectoralis major (clavicular head), coracobrachialis, and biceps brachia are the synergists for shoulder flexion. For horizontal flexion, the Anterior deltoid is the synergist muscle.

I would say that the rectus abdominis would be the main muscle associated with trunk flexion, but the external and internal obliques also perform trunk flexion.
the word horizontal means: flat or level: a horizontal position. "The line is horizontal to the ground" would work.....
Flexion (same as bending) at the elbow joint (between the humerus and the radius and ulna) is mainly achieved by the Brachialis Muscle. This is not the answer most would expect as everyone knows the Biceps Brachii (Biceps of the arm) are what flexes this joint. In fact the biceps does both supination and flexion of the elbow because its insertion is on the radius. Only when the forearm is supinated, the biceps is able to assist the deeper and more powerful brachialis muscle with the flexion of the elbow.
what best decribes the ideology associated with the civil rights movements
a game played on a court by two opposing teams of 5 players; points are scored by throwing the ball through an elevated horizontal hoop
Yes, and knee extension would be when the knee is straight.
