What
is the independent variable in this Procedure? What is the dependent
variable? Explain how you know.
Write
a hypothesis statement for the experiment you conducted for Procedure I. Note:
this hypothesis should address the entire experiment, not simply one portion of
it.
5. Looking only
at the data contained in Table 2, did any of your Unknown Solutions (A, B,
C, D or E) react to the same Test Solutions (1, 2, 3, 4 or 5)? If yes, which
one(s)? Use your understanding of biomolecules to explain why this happen.
Yes, Unknow Solutions A reacts to Test
solutions 4 and 5, Unknow solution B react to test solutions 1, Unknown
solutions C responds to test solution 4, Unknow solution D reacts to test
solutions 3, Unknow solution E reacts to test solutions 1 and 2.
6. Using only at the data contained in
Table 2 and your own knowledge of biomolecules, did any of your Unknown Solutions
contain reducing sugars? If yes, which one(s). Explain how you know.
7. Imagine you were given two solutions and were
told that one contained amino acids and one contained a protein, but you were
not told which was which. You were then asked to determine which solution had
the larger molecules. Using the lab tests in this experiment and your own
knowledge of biomolecules, would you be able to determine this? If yes, explain exactly what you would do and
the reasoning you would use to make this determination.
8. Which
Test Solution (1, 2, 3, 4 or 5) from Procedure II would pure olive oil react
with? Explain.
