EXTRA CREDIT – up to 3 points   Norepinephrine binds to a cell via a G-coupled Protein receptor and Adenylyl cyclase to produce a cellular response. Phoebe drank a lot of coffee this morning and is now more wide awake than normal.  Explain physiologically what happens normally with this G-coupled Protein process (molecule binding to a G-coupled protein receptor) Explain the physiological reason caffeine is making Phoebe more awake.   (Walk through step by step how the cell would normally respond and stop the signal (part 1), then where and how caffeine changes things (part 2))

Which of these is NOT a reason that Mendel used pea plants as a model to study inheritance?

Biological Evolution is defined as 

In an experiment with corn that had 4–6% oil content, high and low oil content were selected for by breeders. After 75 generations, lines with 18% and 1% oil were produced. This illustrates 

The major difference between natural selection and artificial selection is
