A muscle on the front of the upper arm is called the biceps. The "short head" and "long head" of the biceps function as a single muscle.The triceps, also known as triceps brachii, is a large muscle on the back of many vertebrates' upper limbs that is known as the "three-headed muscle of the arm" in Latin. The long head, lateral end, and medial end makeup its three components.
Tendons, which are strong connective structures, hold the biceps to the arm bones. The proximal biceps tendons are the tendons that attach the biceps muscle to the shoulder joint twice. The distal biceps tendon is the tendon that connects the biceps muscle to the forearm bones (radius and ulna). When the biceps muscles contract, the forearm is pulled up and rotated outward.

Answer:
The control experiments have control variable the natural experiment control by nature lacks this
Explanation:
When a n experiment is set up to answer a particular questions,by subjecting the investigating subjects or individuals to experimental factors beyond the control of the investigator but control by nature,such experiment is said to be Natural.Since the investigator lacks control over the factors determining the experiments.,then natural experiment are observational studies.Therefore they are said to lack controlled variables.
In order to test hypothesis or theories,experiments can be set up by the investigator under certain regulated factors.Thus the variable to determine the effect on the subjects or individual of the investigating conditions can be manipulated by the investigator. Hence it can be said to have a control variable.The experiments is called control experiment.
