A student hypothesizes that placing blood cells in high concentrations of salt water will cause them to grow and eventually lyse, or burst. He performed an experiment in which he submerged blood cells in various concentrations of salt water and recorded his results in the table below.
All conditions were kept the same except for the salinity of the water.
Salinity Cell Diameter
(in micrometers) Lysis?
0.0% N/A Y
0.3% 8.0 μm N
0.6% 7.4 μm N
0.9% 6.6 μm N
1.2% 6.0 μm N
Does the student's data support his hypothesis?
A.
No; cell lysis never occurs.
B.
Yes; the cells grow with increasing salinity.
C.
There is not enough information to tell.
D.
No; the cells shrink with increasing salinity.
