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:
Once a first aider begins to provide first aid, a duty of care is established and the first aider then has a legal obligation to fulfil the duty of care. If a road user is involved in an accident, there is a legal requirement to stay at the scene, assist the injured and report the incident to the police.

Answer:
We have to find out about whom we can go to for our own needs and the requirements of our family, so we can generally search for them in the midst of crisis or for alternate course of action
Explanation:
We have to find out about whom we can go to for our own needs and the requirements of our family, so we can generally search for them in the midst of crisis or for alternate course of action, in the event that a cataclysm or emergency happen and with the end goal for us to realize who are the ones we have to reimburse
