Answer:
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)
This is your own opinion. Write about what you would do as a forensic scientist and the good things about that job and vise versa for the least favorite.
Photosynthesis Is generally the opposite of cellular respiration. To drive the organisms metabolism photosynthesis has an exothermic reaction.
Answer:
The cell membrane is permeable to small solutes to let them easily diffuse in and out of the cells.
