A researcher made an interesting observation about a protein made by a ribosome on the Rough ER and eventually would find its way into the plasma membrane. The protein in the membrane is slightly different than the one made on the ER. How is this possible?
modified by the golgi bodies

For a plant cell to swell and maintain turgor pressure it must exist in what type of environment?
What is hypotonic

This is the stage where the template strand of DNA is read by a protein and strand of RNA is synthesized.
What is transcription

Tropical birds called oilbirds nest in caves and emerge at night to forage for seeds. A biologist thinks that oilbirds might be able to avoid obstacles in their caves by making sounds and listening to echoes. Describe a controlled experiment that the biologist could do to test her hypothesis.
multiple answers. must include control group, experimental group. only 1 variable.

Briefly explain why all starch molecules are pretty much the same, but there are millions of kinds of protein molecules.

Starch molecules are made up entirely of glucose, proteins are each made up of some combination of amino acids (of which there are 20).

What is translation

Jason tried a new fertilizer called MegaGro™ on his garden. He said, "I used it on all my tomato plants this year, and they grew much better than they did last year! MegaGro™ is fantastic!" Was Jason's test of MegaGro™ scientifically valid? Why or why not?
no, no control group
