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)
Answer: 1.B). Evolution genetics.
2.C). Less Bacteria becoming resistant to the specific Antibiotics .
Explanation:
Evolution genetics is field of science, which includes study of genetic variations that lead to evolutionary changes in organisms. As some bacteria had changed their DNA that led to development of antibiotic resistance in them.
Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them
Thus, the correct options to be filled in the blanks are option (B) and option (C).
The volume of the cube increases by eight.
