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.

Answer:
haploid/diploid
Explanation:
The number of chromosomes can also be expressed as <em>haploid or diploid</em>, instead of 1n for one copy and 2n for two copies.
The <u>haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms</u> while <u>the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms. </u>
So, in other words: n = haploid and 2n - diploid.
