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.

because direct and indirect costs are the major costs involved in the production of a good or service. While direct costs are easily traced to a product. indirect costs are not.

She feels the need to do that ritual of ringing the doorbell 10 times no matter what, which means she has ocd.
Some parts of out body itch because of many reason they might be
•Dry Skin
•Bug Bites(bedbug/lice/scabies)
•Itchy skin condition
•Allergic reaction
•Skin Cancer
•Warning of a disease (Diabetes/HIVetc)
(There are other reasons too like:
•Reaction to plants and marine life(poison ivy/other plants you might be allergic to/water/pond)
•Nerve Problem)
Anyways it ming not be something to be afraid of because sometimes my skin too itches without any reason. It can be that we have a dry skin. But if you want to you can go to a dermatologist. Just remember that it is okay to have some rashes and itches. Stay safe
