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 worker must discard the shrimp, since this type of food must always be kept frozen, to avoid its deterioration.
Explanation:
The deterioration of shrimp is due to the multiplication of bacteria. At adequate freezing temperatures, bacterial multiplication is prevented or stopped. Freezing is a very effective method that is used to preserve fish and shrimps for months and to preserve the original quality, both hygienic and nutritional and organoleptic.
Answer:
I think your answer would be AED
Explanation:
sorry if this is wrong
hope this helps tho
Answer:
Complementary angles
Explanation:
Complementary angles. Because ∠EFB = 90° ⇒ ∠EFA = 90°
∠AFC + ∠EFC = 90°.
Hence, the correct answer is complementary angles.
Answer: Precision agriculture
Explanation:
Precision agriculture is an agriculture practice which involves the satellite farming. It is a farming management system that is based upon observing, responding and measuring the variety of crops in an agriculture field.
This process uses the computerized methods and equipment to control the use of nutrients, seeds, irrigation, and water in a strategic and sparing way to reduce the cost, efficiency and reducing the adverse impact of the environment.
