Personality traits can be shown at different levels, they are <u>C.</u> explained in five areas.
<h3>Personality traits</h3>
Many modern and traditional studies in psychology point to 5 basic personality dimensions. Evidence for this theory has grown over the years, with the emergence of the theory of principles in 1949. The five broad personality traits described by the theory are
- Extraversion
- Agreeableness
- Openness
- Conscientiousness
- and Neuroticism.
With this information, we can conclude that personality traits are divided into five areas which are extroversion, agreeableness, openness, conscientiousness and neuroticism.

Answer:
When skeletal muscles are trained by adding physical stress to them, this is called progressive resistance training (PRT).
Explanation:
During PRT, muscles are exercised against an <em>overload or resistance</em>; the overload is gradually increased in order to allow muscles to adapt. This allows for progressive strength increases over time.
Muscle fatigue is defined as a reduction in the ability to produce force due to exercise. This comprises:
- peripheral fatigue- due to changes at the junction between motor neurons and the muscle.
- central fatigue- caused by a reduced capacity to use voluntary force in relation to the capacity to use involuntary force
- and muscle damage- this is associated with several issues at the cellular level such as disrupted membranes and cytoskeletons; and tissue damage via torn muscle fibers, and collagen.
Overall, these may affect muscle fiber activation and the amount of force they are capable of producing- i.e. sustained strength. However, muscle fatigue can be greatly reduced via the maintenance of PRT. Also, apart from strength gains, PRT is <em>used for weight loss and muscle building</em>; common tools used in PRT include <em>free weights, elastic bands and exercise machines. </em>
