Answer:
D. provide the most compelling evidence of cause-and-effect relationships.
Explanation:
After performing gel electrophoresis on the pcr product, you see that one sample has a 200 bp band and the other does not this shows that 200 bp band is significantly larger than the size of primer dimers unless the primers are 100 bp long, they are not visible.
Gel electrophoresis is the process used to evaluate the success of the PCR reaction.A closer examination of the suitability of agarose gel electrophoresis is done for assessing PCR product yield.
PCR is a series of chemical reactions that take place outside a living cell
Use of 2% agarose gel and 100bp marker and spreading the marker strips properly with 80-90V is done to avoid heating.

Answer:
Explanation:
The wording on some of these choices is very strange; I'm not sure exactly what they are stating. First of all, A. is definitely a choice because if both the charges were opposite, they would be attracted to one another as opposed to be repelled away from one another, as they are when they are both positive. What happens is that the charges go OUT from the positive charge and INTO the negative; so as far as the field lines around both charges would change direction...no; only the direction of the field lines would change on the positive charge (which is the one on the left). In that space where D is filled in by the field lines going OUT of the positive charge and INTO the negative one, the lines there are naturally closer together, and that is the point where the charge is the greatest. So if that is what is meant by the field lines getting closer together, then yes, they do. As far as choice D. again the field lines on the negative charge don't change, only the ones on the positive charge change.
The statement ‘An advantage of
electron microscopes compared to light microscopes is that electron microscopes
are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes
do not have higher resolution that allows you to view smaller specimens allow
you to view the true colors of the specimens being viewed’ is true. In fact,
electron microscope is more efficient than a light microscope due to its
mechanism using only light without magnifying the specimen a thousand times.
