A cell, when exposed to an environment where the external H2O potency is less negative than the internal H2O potency, will free H2O by osmosis down a concentration gradient. Conversely, when exposed to an environment where the internal H2O potency is less negative than the external H2O potency the cell will take in H2O from…

Osmosis is the motion ( natural ) of a dissolver, in the instance of life beings ( H2O ) selectively through a semi-permeable membrane down a H2O possible gradient. In other words it is the motion of H2O across a selectively semi- permeable membrane from an country of high H2O potency ( low solute concentration…

Introduction Atrial fibrillation is the most common signifier of cardiac arrhythmia ; it involves the two upper Chamberss of the bosom known as the atria. During atrial fibrillation the normal pulsations generated by the sinoatrial node are overcome by the electrical pulsations that are generated in the atria and pneumonic venas, which leads to irregular…
