Answer:
The correct answer is B. clavicle articulates with the manubrium of the sternum.
Explanation:
The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. The sternal end is also anchored to the first rib by the costoclavicular ligament. The medial end, also known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.

Answer:
Even though a motion picture actually consists of a series of still frames, we perceive them conveying continuous movement. This is an example of stroboscopic effect.
Explanation:

Answer:
The correct answer is: the group of 10 people that lifted the barbell with music is the control group.
Explanation:
The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.
The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.
<u>The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell</u>. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.
