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.
It's more accurate, especially since heart rate is almost universally measures in beats-per-minute, than, say, timing your pulse for a [factor of 60] seconds (30 seconds, 20 seconds, 15 seconds, 12 seconds, etc.).
The challenges of molecular biology in clinical practice include:
- lack of funds to support clinical application of molecular biology
- ethical issues regarding the application of molecular biology in clinical practice
<h3>What is molecular biology?</h3>
Molecular biology is the study of biological molecules at the molecular level.
Molecular biology involves the study of such molecules as DNA and RNA and how the affect the production of macromolecules such as carbohydrates, proteins and lipids.
The challenges of molecular biology in clinical practice in recent times include:
- lack of funds to support clinical application of molecular biology
- ethical issues regarding the application of molecular biology in clinical practice
In conclusion, molecular biology is biology at the molecular level.

Medical terminology ultimately benefits the patient I think is the not true statement because alot of people don't understand the vocabulary/language that doctors use
