The independent variable is the thing that changes with in the experiment to make it an experiment. For example, say I was doing an experiment on something such as "Which sponge brand can absorb the most water?" The independent variable would be the different sponge brands because it would be the thing that changes with in the experiment. Otherwise, if you didn't make an independent variable (the different sponge brands in this case) it wouldn't be an experiment because a sponge of the same brand should hold about the same amount of water as the others.
An important measure for controlling bias (APEX)
What a person intends to do in an experiment depends on what the experiment is. Someone will need to know what the exact experiment is to know what they would do in it.
The more scientists that conduct the same experiment, with the same results, the more the findings can be trusted. Also, more scientists are more likely to come up with variances or solutions due to different ways of thinking and approaching things.
Be clear about the purpose of the experiment.
warm water
Nitrogen is not commonly used as a disinfectant. Disinfectants are typically chemical solutions or agents that are specifically designed to kill or inactivate microorganisms. Nitrogen is an inert gas and does not possess disinfectant properties.
Possibly, if not rinsed.
you have a different variable
You would need to do the experiment to know how many new shoots grew from each potato 'eye', because it would be different in each experiment, with each potato, with different immersion in water, etc.
In this experiment, the independent variable would be the amount of alcohol consumed by the participants. Different amounts of alcohol would be administered to different groups to observe the effect on memory.
Your results might be different then these but I hope this will give you an idea for an answera. In our lab we observed growth in all of the test tubes. Originally we had hypothesized that the tubes with higher concentrations of disinfectant would inhibit the growth of the inoculated organism. This experiment allows us to conclude that the disinfectant is not very efficient. Although we were able to come to a conclusion, our results are limited to the organisms that we used to inoculate the test tubes. Different organisms might be more resistant to the disinfectant. A conclusion that the disinfectant we used is inefficient with all bacteria cannot be made.
Well in the case that it does have a variable, even just one, it would still be a variable experiment because that one part of the experiment may still cause a different effect/result when changed!!!

To experiment is a verb. An experiment would be a noun.
To properly disinfect an item, it would need to be saturated or immersed in a disinfectant solution for at least 10 minutes. But, 15-20 minutes would be better. If you are trying to sterilize the item, you would need to leave it soaking for at least half an hour.
