Assume you are growing a bacterial culture in a glucose medium. your lab partner adds more glucose in hopes of speeding up the experiment. the bacteria suddenly die. the best explanation for this result is that

Bacterial cells died because they plasmolyzed. when higher amount of glucose was added in the medium, the medium became hypertonic in comparison to plasma of the bacterial cells. As a result, water moves from the cells to medium by osmosis making the cells to shrink and lose their normal functioning which cause their death.  

From our previous experiment, we examined how many drops a penny can hold - and place drops of salt water on the penny after recording 5 trials each, take the average of each solution.
