The RR interval of ECG vary during normal respiration because of the sinus arrhythmia.
The contour lines on a map indicate changes in elevation above sea level (or below, occasionally). The amount of change in elevation between lines is shown on the map legend, and will vary depending on the size of the map and the type of terrain.
A normal fasting blood sugar will vary between 70 and 100 mg/dl. It can shoot up to 140 mg/dl after a person eats.
yes
yes, animals, by definition, consume food (carbs, lipids, proteins) so that they can break it down. carbs (specifically glucose) undergo oxidation to put its bond energy into ATP (adenosine tri phosphate).
By night, one must assume that you mean during sun-less periods. At the South Pole, the sun-less period is about six months and the temperature during that period averages between minus 65 and minus 75 degrees F. Elsewhere on the continent, the sun-less periods vary as does the temperature, which is always extremely cold.
This will vary widely and will depend on several things including age, fitness, activity level and health issues. It also depends on whether you are talking about resting respiration or respiration during exercise.
both intrapleural pressure and intra-alveolar pressure.
Yes. The mechanisms vary but the answer is yes.
In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2
Normal results vary by age and by sex. They also vary based on the laboratory and the method used.
It could be normal. During pregnancy you usually have more discharge and they usually vary from watery to thick. If it concerns too much you ask your doctor about it.
In general, respiration rate is 12-20 respirations/minute and pulse rate is 60-100 beats/minute. The rates vary so it is important that you determine your "normal" rates for various activities.
It can vary from say a Cessna to an A330
Depending on when you go, it can vary. During the summer, waits can exceed 3 hours for some rides. The least crowded time is usually during October, the average wait then is from no wait to 30 minutes at max.
Microcytes are smaller than normal macrocytes are larger than normal. Methods of defining normal vary from lab to lab.
Normal results for adults vary, but in general are: male - 13.8 to 17.2 grams per deciliter, and female - 12.1 to 15.1 grams per deciliter. Normal value ranges may vary slightly among different laboratories.
nipples vary in size, so yes they're normal.
