So, the fact that it's a specific instrument doesn't change why you need to correct the data.
However, for this question it is important to know the instrumentation.
Since respirometers are measuring the <span>C<span>O2</span>:<span>O2</span></span><span> relation, clearly having biotic material and abiotic material will change the measurements.
You should be able to figure out that the general gas law is coming into effect because of the act of cellular respiration.
In general terms, you are correcting your instrument to a known blank (you do this with scales and every other instrument).
By determining the reading for the blank (marbles) you can know the relative error of the instrument.
Taking a scale for example: You 0 the scale to a mass of importance (the amount of error you're okay with) and then use it for your measurements so you can be adequately confident of the mass you're measuring .</span>
Answer:
The ingestion of a meal high in fat content would cause <em>obesity </em>to occur.
The correct answer is Vibration.
This is a condition in which there is a involuntary eye movement. In this the eye seems to be dancing eye and the vision is not clear. The vibration in eyes is due to consumption of alcohol. In normal condition the blinking of eyes is voluntary but due to consumption of alcohol the condition changes and the blinking of eyes becomes involuntary(neurological disorder).
