Which component of the electrocardiogram represents the duration of ventricular contraction?
Advocard [28]

QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).

Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.

P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

Ocean water is sinking at the North Atlantic Buoy Station. What happens when water of a high density sinks?
svp [43]

<u>Answer:</u>

<em>Ocean water is sinking at the North Atlantic Buoy Station the given things have occurred.</em>  

<u>Explanation:</u>

The way of thermohaline course starts at high scopes, where cold seawater sinks due to its generally high thickness.  

In the Northern Hemisphere, profound sinking to 2000-3000 meters happens just in the North Atlantic, not in the North Pacific on the grounds that the waters of the North Pacific are freezing and not as salty as the waters of the North Atlantic.  

In this way, Earth's profound sea bowls are loaded up with waters from the northern North Atlantic and those that sink close to Antarctica.

The action of a buffer to maintain ph within normal limits involves __________.
lozanna [386]
A buffer is a solution encompassing a weak acid and its conjugate base in alike amounts. This combination reduces the pH change upon addition of strong acid or base by converting H1+ (or OH1-) to weaker acids or bases. This primarily consist of compounds that stabilize the pH of a solution by removing or replacing hydrogen ions. Also, substances that resist change in pH.
