Directions: Answer the following questions and post your responses within your class’s online collaborative tool for all of your classmates to review.
Answer the following
questions on your online collaborative tool.
- You completed the
worksheet “Not Just How Much—How Much, How Often.”
- What insights did you
gain about how identical daily doses can lead to very different effects?
- Are "natural" sources better than
supplements? Why or why not?
- You have already
exploited an experimental system (seeds, petri dishes, and salt
solutions) to design an experiment that measures an acute response to
salt in plants. Since then, you have learned a number of extensions and
refinements to the concepts of dose and response, and median lethal dose
(or, in this case, median germination failure concentration).
other experimental designs could you propose? For example, to measure
the chronic effects of salt on plants? Or the effects of different kinds
