<span>If Noam chooses a filter, it might be more effective than a screen. After using it for a while, though, he will have to replace it, which could be expensive. A screen might be less effective, but it can be cleaned instead of replaced.</span>
Answer- D. Mutualism
Reason - Frog is using water pools of water collect by flower. Which benefits the frog :)
Then the frog also dispersed its waste which then also the flower can use for its benefits. So in all it's mutualism
Answer:
<h2>A</h2>
Explanation:
1. As given, the of a strand DNA contain sequence;
A-T-G-C-C-A-T-C-G-G-T-A,
2. After exposure to UV light, the strand contain the bases;
A-T-G-G*-C-C-A-T-C-G-G-T-A,
3. By comparing both the strands, we find that, the strand of DNA after exposure to UV contain extra G nucleotide between G and C, which is resulted by an insertion.
So we can say that, a new base has been inserted.
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>
