Question

Think about the lab procedure you just read. Label each factor below V if it was variable during the procedure or C if it was constant.
molecule size (large starch molecules vs. small glucose molecules)
material used as the membrane
amount of substances used
number of trials
whether the molecules diffused through the membrane (tubing)

Answer 1

Answer:

The factors which remained constant are as follows -

1. material used as the membrane
2. amount of substances used
3. number of trials

The factors which have shown variation are as follows -

1. molecule size (large starch molecules vs. small glucose molecules)
2. whether the molecules diffused through the membrane (tubing)

Explanation

Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -

1. material used as the membrane
2. amount of substances used
3. number of trials

The factors which have shown variation are as follows -

1. molecule size (large starch molecules vs. small glucose molecules)
2. whether the molecules diffused through the membrane (tubing)

Answer 2

Answer:V,C,C,C,V
