Just four questions:
In a controlled experiment, why should there be several individuals in the control group and several in each of the experimental groups?
A scientist who studies mice observes that on the day he feeds the mice vitamins with their meals they preform better in mazes. What hypothesis would you form to explain this phenomenon?
The volume of an egg and water in a graduated beaker is 200 mL. After the egg is removed, the volume of the water is found to be 125 mL. What is the volume of the egg in cm3?
If you magnified a 5 um long organism 1,000 X, how long would that organism appear in millimeters (mm)?
I'd hate to ask these, but I have to answer each of them in one or two sentences. I can only think of long paragraphs, and when I try to cut them down, they just sound terrible.
Thanks in advance.
I really need to finish this tonight because my Educational Supervisor comes in the morning and this is the last bit of work that I need to finish and my dad has already gone to sleep. THANKS!
