Is the amplitude of each wave (P, ORS, T) always the same in different cardiac cycles?
Citrus2011 [14]

No the amplitude of each waves are different on different cardiac cycles.

<u>Explanation:</u>

  • The PQRST waves are used to represent the atrial and ventricular depolarization and repolarization.  These waves are reflected in ECG.  
  • In this as the series, p occupies the first place then QRS complex and at last T wave. In the QRS wave complex,  R wave is said to be the largest wave.

Does lemon juice have more or less H+ ions than it has OH- ions? explain
LekaFEV [45]

Acids are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH–) and raise pH. The stronger the acid, the more readily it donates H+. For example, hydrochloric acid and lemon juice are very acidic and readily give up H+ when added to water. ( source : https://courses.lumenlearning.com/wmopen-nmbiology1/chapter/the-ph-scale/ )
