Answer:
True.
Explanation:
Stage 1 of NREM sleep is characterized by a low amplitude EEG, mixed frequency between range a and s (2 to 7Hz). EMG activity is usually higher than at other stages of sleep, but amplitude can vary widely. Stage 2 of NREM sleep is recognized by background activity and episodes of sleep spindles and K-complexes. Sleep spindles are short (12 to 14 Hz) waves that increase and decrease in amplitude to produce a spindle characteristic. Stage 3 NREM sleep is classified when slow waves or d waves (£ 2Hz) and high amplitude greater than 75mV (measured from lowest to highest wave - peak to peak) appear at 20 to 50% of the time of the day. record. Stage 4 NREM sleep is similar for EEG, EMG, and EOG from the previous stage; however, stage 4 is characterized by the presence of d waves in more than 50% of the time.
Accordingly, we can conclude that going through the NREM stages (1 to 4), the frequency of EEG waves decreases but their amplitude increases.
Answer:
C. Both represent major components of the FITT principle.
Explanation:
A good health can be defined as the state of well-being in which all of the components of an individual's health are in balance. These state of well-being comprises of six (6) important components and they are; physical, spiritual, emotional, environmental, social and mental or intellectual. In order to have a good health, physicians and medical professionals advise individuals to engage in physical activity such as an aerobic exercise.
Aerobic exercises refers to all forms of physical activity that an individual engages in, in order to increase the heart rate (from low to high intensity) in response to the level of oxygen required by any activated or working muscle in the human body.
Basically, fitness experts usually advises everyone to judiciously engage in physical activities or exercises so as to improve their well-being, wellness or heart health.
Progression and variation are similar because both represent major components of the FITT principle.

Answer:
Barometric pressure
Explanation:
Dysbarism injury is a number of signs and symptoms the occurs as a result of exposure to severe, changing and very low barometric pressure.
Dysbarism injury occurs during diving. Symptoms of dysbarism includes: Headaches, extreme tiredness, heart attack, problems with breathing, pain in the joints, pain in the chest, itching, vomiting e.t.c.
