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 co
nstant. 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)
The factors which remained constant are as follows -
material used as the membrane
amount of substances used
number of trials
The factors which have shown variation are as follows -
molecule size (large starch molecules vs. small glucose molecules)
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 -
material used as the membrane
amount of substances used
number of trials
The factors which have shown variation are as follows -
molecule size (large starch molecules vs. small glucose molecules)
whether the molecules diffused through the membrane (tubing)
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles.
