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.
If you do not have options, I believe your answer is obesity.
If you do have options and this isn't one of them, please comment on this question and tell me what your options are. I would love to help.<span />
True. The left side of the heart receives oxygenated blood from the pulmonary vein and pumps it into the aorta, while the right side of the heart receives deoxygenated blood from the vena cava and pumps it into the pulmonary vein.
Answer:
In order to implement "privacy" in a computer system, we need a more precise definition. We have to decide when and under what conditions to give out personal information. Specifically, we must decide when to allow anonymous transactions and when to require accountability. If there are subgroups in society, or countries, with differing ideas about the answers to these questions, technology can, to a large extent, accomodate each group. There does not necessarily have to be only one privacy regime. Less law and more user choice is possible now; technology can provide every user with controls fine-tuned for the balance of privacy and accessibilty that they prefer.
