Antibiotics generally take a week
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:
healthy body weight
Explanation:
A healthy body weight is one that makes you less likely to develop the various problems caused by excess body fat - especially some cancers, but also heart disease and diabetes, among others. Being overly thin or overly fat can be harmful, so you should aim to stay within the limits of healthy body weight. In other words, a healthy body weight is a weight (or BMI) that does not increase your risk of developing health problems or weight-related illnesses.
It is difficult to define an exact and healthy weight for each person because it would entail knowing the amount of lean (mostly muscle) tissue of each individual, which can only be done in a research lab.
Energy balance also has to do with what’s going on in your cells. When
you’re in a positive energy balance (more in than out) and when you’re
in a negative energy balance (more out than in), everything from your
metabolism, to your hormonal balance, to your mood is impacted.
