natural selection, bc it is the process whereby organisms better adapted to their environment tend to survive and produce more offspring
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)
Because the chain will begin to shut down and will no longer pump [H+] (hydrogen ions) across the membrane; thus, the proton gradient can not be maintained.
:) I hope this answers your question!
One strand runs in the 5 to 3 and the other in the 3 to 5
