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)
The answer is; providing one-on-one supervision during meals and for one hour afterwards.

The right answer is A. greater leaf surface area.
In botany and agronomy, the specific leaf area (SFS) is defined as the ratio of the leaf area to the dry weight of the leaf (expressed in m².kg-1).
The specific leaf area reflects the "thickness" of the leaves and has a particular physiological significance. This parameter is correlated positively with the photosynthetic capacity of the plant.
The specific leaf area can be used to estimate the reproductive strategy of a particular plant based on, among other factors, light and moisture levels. The specific leaf area is one of the most widely accepted key features used in the study of leaves.
