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:The Dietary Guidelines for Americans
Explanation:
The Dietary Guidelines for Americans produced by the HHS and the U.S Department of Agriculture is a nutrition information designed for individuals from two years and above to make healthy diet and lifestyle choices. This guideline is usually reanalyzed every five years to make sure set guidelines are at par with latest and improved research of which the last was modified in 2015, and would run its course through this year, 2020
Having Healthy eating habits which includes consuming foods like vegetables, fruits, whole grains, fat-free and low-fat dairy products, lean meats, seafood, other protein foods, and oils together with healthy lifestyle such as regular physical activities, have been shown to reduce risks of chronic disease such as diabetes mellitus, obesity, certain cancers etc throughout their lives.
I believe that this would be deforestation because the trees' roots keep the soil in place whereas if they were gone the soil would be loose.
