question 64

Multiple Choice

You have two flasks (labeled A and B) that each contain an equal population of normal animal cells. You place flask A in a machine called a shaking incubator, which shakes the flask at 37°C and keeps the cells moving so as to not allow them to adhere to the bottom of the flask. Flask B is allowed to sit in an incubator (without shaking) at 37°C. If you let the cells in each flask grow for a week, which of the following results are you most likely to observe?

• A) The cells in flask A will have grown significantly, but the cells in flask B will have not grown at all.
• B) The cells in both flasks A and B will have grown significantly.
• C) The cells in both flasks A and B will have not grown at all.
• D) The cells in flask B will have grown significantly, but the cells in flask A will have not grown at all.
