The right answer is False. (An important element missing from the definition of motor unit are motor neurons.)
A motor unit is composed of an alpha motor neuron and the muscle fibers it innervates.
Groups of motor units often work together to coordinate the contractions of a single muscle. All motor units that serve the same muscle are considered to be a group of motor units. The number of muscle fibers connected to each unit can vary: the muscles of the thigh can have up to a thousand fibers per unit, the muscles of the eyes can have only ten. In general, the number of muscle fibers involved in a motor unit is a function of the muscle's need for its refined movement: the more the muscle will need a fine movement, the less the motor unit will involve synapses with the muscle fibers.

Answer: Tina should worry about the fever first and get a ice pack or a cool rag to get him to his normal temperature. Doing that will make him comfortable...well at least a little. The child has pyrexia so medications such as acetaminophen and ibuprofen may help ease discomfort. Since this is a child, avoid giving him aspirin because this may cause a rare, serious condition.
Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. Examples would be cycling, running, swimming, jogging, etc.
