A drop of blood is added into a solution and found that red blood cells will hemolyse. what solution it might be?
ioda

The solution might be hypotonic.

When a drop of blood is added in the hypotonic solution, it may hemolyse Or bursting of cell take place, this is because the solvent comes inside the cell due to lower concentration of solute and it becomes hemolysed.

There are three types of solutions.

  • Hypertonic condition of the solution occurs when the concentration of solute outside is higher than that inside the cell.
  • Hypotonic condition of the solution occurs, when the concentration of solute outside is lower than that inside the cell.
  • Isotonic condition of solution occurs when concentration of dissolved solute outside is equal to the concentration of solute inside the cell.

To learn more about hypertonic and hypotonic solution, refer this link.

According to this question, if both parents are heterozygous for both Rh and normal insulin production and cross, i.e. RrIi × RrIi, the following phenotype of offsprings will be produced (see punnet square):

- Rh, normal insulin (R_I_)

- Rh, no insulin (R_ii)

- Rh-, normal insulin (rrI_)

- Rh-, no insulin (rrii)
