Question
Relate what you know about what happened to the RBCs that were added to distilled water and to 0.4M NaCl to the respective appearance of the solutions themselves. In other words, both solutions are reddish, but one is transparent and the other is opaque. WhyRelate what you know about what happened to the RBCs that were added to distilled water and to 0.4M NaCl to the respective appearance of the solutions themselves.

Explanation / Answer
When RBCs were added to distilled water, water flows into the RBC due to diffusion. This is because; distilled water is hypotonic to the RBC. So, RBCs bulge out and break down. This will result in the transparent red solution.
When RBCs were added to the 0.4 M NaCl solution, this solution was activing as isotonic solution that means, both the solute and solve concentrations are very much similar. Isotonic solution keeps the RBC in their native size and shape by allowing equal inward and outward flow of water. Hence, this solution is reddish, yet opaque.
