Salt Bridge

A salt bridge is a means of connecting the oxidation and reduction half-cells of a galvanic cell (voltaic cell), which is a type of electrochemical cell.

The most common type of salt bridge is a U-shaped glass tube, which is filled with an electrolyte solution. The electrolyte may be contained by agar or gelatin to prevent intermixing of the solutions. Another way to make a salt bridge is to soak a piece of filter paper with an electrolyte and place ends of the filter paper in each side of the half-cell. Other sources of mobile ions work too, such as two fingers of a human hand with one finger in each half-cell solution.

Osmosis - Blood Cells

The effect of osmotic pressure on red blood cells in shown.
The Effect of Osmotic Pressure on Red Blood Cells The effect of osmotic pressure on red blood cells in shown. From left to right, the effect is depicted of a hypertonic, isotonic and hypotonic solution on red blood cells. LadyofHats, Public Domain

Hypertonic Solution or Hypertonicicty

When the osmotic pressure of the solution outside the blood cells in higher than the osmotic pressure inside the red blood cells, the solution is hypertonic. The water inside the blood cells exits the cells in an attempt to equalize the osmotic pressure, causing the cells to shrink.

Isotonic Solution or Isotonicity

When the osmotic pressure outside the red blood cells is the same as the pressure inside the cells, the solution is isotonic with respect to the cytoplasm. This is the usual condition of red blood cells in plasma. The cells are normal.

Hypotonic Solution or Hypotonicity

When the solution outside of the red blood cells has a lower osmotic pressure than the cytoplasm of the red blood cells, the solution is hypotonic with respect to the cells. The cells take in water in an attempt to equalize the osmotic pressure, causing them to swell and potentially burst.

The Calvin Cycle is also known as the C3 cycle, Calvin-Benson-Bassham (CBB) cycle or reductive pentose phosphate cycle. It is a set of light-independent reactions for carbon fixation. Because no light is needed, these reactions are collectively known as 'dark reactions' in photosynthesis.
