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>
I believe it's smaller and less rounded. Hope this help, God bless!
We see that this is a region near the continents, so it is probable that there is the boundary of a tectonic plates around there. Since there are islands there, it is quite probable that there is a subduction zone near them which means that the oceanic crust is going below the continental one and the continental is slowly elevated. This also shows that the boundary is convergent, since transform boundaries do not lead to elevation. Near convergent boundaries, there are frequently volcanoes and shallow earthquakes. Finally, the climate near Alaska is cold and this does not depend on whether islands are near a boundary or not. So, 2 4 and 5 are correct.
<span>After the third month of development, lanugo develops on the head (thin, first hair), the muscles and bones are formed an shaped, the mouth movement is possible, the liver and pancreas produce fluid secretions, meconium is made (stool of infant), reproductive organs are developed, but the baby's gender is difficult to distinguish on ultrasound.</span>
