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.

idk im doing that project rn the module activity right? ahaha
Explanation:
Systemic circulation which is the movement of blood through tissues of the heart carries oxygenated blood from left ventricle through arteries.
Systemic circulation moves blood between the heart and rest of body . It send oxygenated blood out to cells and return the degenerated blood to the heart.
Heart is the only organ in circulatory system organs . blood goes from heart to lung to get oxygen. lungs are the part of the respiratory system. Heart pumps oxygenated blood through artiest to the body. Systemic provide the functional blood supply to all body tissue. Oxygen locks into molecule called hemoglobin in red blood cells.

Lightweight clothing because dark clothing will hold heat, waterproof clothing will stick to you and make you hot, and tight clothing will make you sweaty and hot
As his respiration became shallow, it means that he is going to have difficulty in breathing, so it is best to have a device or assistance to be placed on him, in order to assist his breathing and ventilation. It is best to insert an airway adjuct to him, in order for his breath to widen and to insert a bag mask device, to assist his ventilations.
