According to a national survey of asthma: On May 1, 2010, the number of residents of Oklahoma who had been diagnosed with asthma
ICE Princess25 [194]

Answer:

(C/B) x 100,000

Explanation:

It is given that

According to a national survey of asthma:

"A" is the number of citizens of Oklahoma who had suffered from asthma during their life as on May 1, 2010.

"B" is the  population on June 30, 2010.

And "C" is the number of new cases registered for asthama in the same year that is in the year 2010.

Thus the incidence rate per 100,000 of asthma is expressed as (C/B) x 100,000

That is the ratio of new cases registered for asthama inthe year 2010 to the population of Oklahoma in the year 2010 multiplied by 100,000.

Thus the answer is (C/B) x 100,000

sergey [27]

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.

Artyom0805 [142]

Answer:

a. QRS

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

The QRS complex represents the time necessary for the impulse to travel through the bundle of His, the bundle branches, and the Purkinje fibers to complete ventricular activation or contraction, known as ventricular depolarization. QRS is simply a combination of the Q-wave, R-wave and the S-wave which represents electrical impulses.
