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)

<u>The four types of interactions in communities are:</u>
- Mutualism
- Parasitism
- Commensalism
- Competition
<u>Definition of each interaction:</u>
<em>Mutualism: </em>
The type of interaction in which both the species involved are benefited, it is called mutualism.
<em>Parasitism:</em>
The type of interaction in which one species is benefited, whereas the other is harmed, it is called parasitism.
<em>Commensalism:</em>
The type of interaction in which one species gets benefited without harming or providing benefits to others is called commensalism.
<em>Competition:</em>
The type of interaction in which both species lose is called competition. It is opposite of mutualism.
<u>Symbiotic relationship:</u>
It refers to the type of interaction in which lastly one species gets benefited. The type of interactions such as <em>mutualism, commensalism, and Parasitism </em>are considered as symbiotic relationship.
