Answer:
B) Prevalence
Explanation:
Prevalence in this case is the number of young women within the age bracket that tested positive for STI this year.
We cannot say this is an epidemic because we don't know if the statistics from the result is normal or higher than what is termed normal. It is also not incidence because incidence has to do with new cases and we were not given enough information to know if it is the first time for those who tested positive or they have tested positive for STI in the past.
Since there are no risk factors involved, we cannot term the data as risk because risk in this case involves the probability of contracting STI.
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.
This disease is called Parkinsons!
