A biologist diluted A blood sample with distilled water. While observing simple with a microscope he noted that the red blood cells had burst. This first thing is most likely the result of which process? 1. Staining 2. Diffusion 3. Digestion 4. Active Transport

The bursting of the blood cell is a result of diffusion of blood molecules from high concentrated area to low concentrated area. In this case, the high concentrated area is inside the cells while the low concentration is detected outside. Movement is going outwards making the cells burst.
