If you pay your bill in full you might avoid paying interest, depending on the rules behind the card. Keep in mind that the actual interest rate for your first card will be MUCH higher than that, so if the card was 20% APR and you spent that same $100 your interest for the month would be more like $1.67.Interest on $1000 would be $16+ a month.f you pay your bill in full you might avoid paying interest, depending on the rules behind the card.

1 In a hypertonic solution, the extracellular fluid has a higher osmolarity than the fluid inside the cell; water leaves the cell.  In an isotonic solution, the extracellular fluid has the same osmolarity as the cell; there will be no net movement of water into or out of the cell.
Now hypotonic, hypertonic, and isotonic solutions usually deal with cellular osmosis which diffuses over a selectively permeable membrane. Osmosis is the movement of water and tends to diffuse by moving the water from areas of higher concentrations to areas of lower concentrations.ypertonic Solutions. Hypertonic solutions are different from isotonic solutions in that cells often lose water. Cells have a water concentration that is greater inside the cell rather than outside of the cell. Furthermore, the solutes outside of the cell are greater than the solutes inside of the cell.
