Answer:
Purpura
Explanation:
These raised reddish purple spots are most likely to be caused by a little pooling of blood under the skin and this condition is termed as Senile Purpura. These spots often fade away as the child ages.
There are no serious complication related to this that may need higher medical attention but some rare serious cases have been seen when the patient also has blood clotting disorder.
Answer:
The correct option is: B. conversion hysteria
Explanation:
According to the Sigmund Freud's psychoanalytic theory, the human behavior can be explained by the unconscious psychic drives of the brain. He believed that the mind is responsible for making all the conscious as well as unconscious decisions. These ideas were made by observing people with conversion hysteria disorder.

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>
