Hi,
Answer: A) Electrons
<u>My work:</u> The outer edge of “Y” is called Elctrons. So your answer would be A) Electrons.
<em>Extra Information: </em>An Electron is a particle of a negative charge.
<u><em>Words you might not know:</em></u>
1) Neutrons - A particle with no charge
2) Proton - A particle with a positive charge
All of these particles are subatomic.
I Hope I Helped!

The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
Answer: absolute certainty is often difficult to achieve. Scientific uncertainty generally means that there is a range of possible values within which the true value of the measurement lies.

This representates the temperature of F degrees Fahrenheit converted to degrees Celsius. Remember that in order to change temperature we need to use the following formula: <span>from Fahrenheit to Celsius: first subtract 32, then multiply by 100/180</span>
