Inulin is a starchy substance found in a wide variety of fruits, vegetables, and herbs, including wheat, onions, bananas, leeks, artichokes, and asparagus.
The P wave in the ECG indicates
a.Atrial depolarization
b.Rapid ventricular depolarization
c.Absolute refractory period
d.Repolarization of the ventricles
The P wave and PR segment is an integral part of an electrocardiogram (ECG). It represents the electrical depolarization of the atria of the heart. It is typically a small positive deflection from the isoelectric baseline that occurs just before the QRS complex.
Plasmids are extra-chromosomal, self replicating, usually circular, double stranded DNA molecules found naturally in many bacteria and also in some yeasts. It was discovered by Willium Hays and Joshua. Lederberg in 1952.
