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.
D. For sure. Hope this helps you!
Answer:
Bone pain, numbness, fatigue, mental fogginess, etc.
Explanation:
Multiple myeloma is a type of cancer which forms in plasma cell (a type of white blood cell). Plasma cell makes antibodies which help the body in fighting against infections but in the case of Multiple myeloma cancer cells crowd out the healthy blood cells and gets accumulate in the bone marrow and rather than creating antibodies cancer cells starts producing harmful abnormal proteins that can cause complications.
It's symptoms include:
- Bone pain, especially in chest and spine.
- Numbness in legs.
- Mental fogginess.
- Infections.
- Weight loss.
- Loss of appetite.
Mostly no because you interact with your peers with the same interest as you
B.
Gia, doesn't like the clothes that are in style but since other people are wearing them she feels pressured to wear them to fit in. If she doesn't wear them maybe her peers will have cause to bully her for being "poor".
