0.9% NaCl, and
9% NaCl.

1. In the figure below, the panel on the left shows how the RBCs appeared in the blood when viewed at 400ร— magnification. Label the three other panels by indicating which shows RBCs added to 0.09% NaCl, to 0.9% NaCl, and to 9% NaCl. Below the panels, indicate whether each solution is isotonic, hypertonic, or hypotonic in relation to RBCs.
