Answer:
- <em>The measurements taken by </em><em><u>Jay</u></em><em> are least likely to contain random errors.</em>
Explanation:
All experimental measures are subject to errors.
Even when the colorimeter is properly calibrated and correctly used, there are random errors.
Random errors are are due to fortuitous factors, such as minor oversight by the observer or small changes of the conditions under which the measurements are made.
You can minimize the random errors by increasing the number of measurements, because the random errors tend to happen in any direction; some measures will be greater and other will be less than the true value.
Chance will make that errors in on direction cancel with errors in the opposed direction, making the average the best measure.
Thus, <em>Jay</em>, by <em>repeating the experiment five times and taking the average measurement</em>, is making that<em> his measurements are</em> <em>least likely to contain random errors.</em>

When atoms of beryllium-9 are bombarded with alpha particles, neutrons are produced, the new isotope will be C-6.
In research, the physicist James Chadwick attacked Beryllium using alpha particles produced by the nuclear reactions of polonium naturally. High radiation penetration through some kind of lead shield was seen, which the then-current particle theories were unable to account for.
There was indeed the production of a carbon-12 nucleus as well as the production of a neutron whenever one blasted beryllium with alpha particles.
The reaction of alpha decay can be written as:
→
Therefore, when atoms of beryllium-9 are bombarded with alpha particles, neutrons are produced, the new isotope will be C-6.

I think the correct answer would be trans fat. These are lipids that are artificially made by adding hydrogen to vegetable oils resulting to a more solid oil. They are called partially hydrogenated oils. They can be found in pies, biscuits, margarine, cakes and doughnuts.
