DNA samples are added into wells with the help of electric current.
<h3>How dna samples added to the wells?</h3>
DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
So we can conclude that DNA samples are added into wells with the help of electric current.

Answer:
The factor that is tested is called the variable.
The variable is also what is changed in an experiment.
Hope this helped! :)
Well fossil fuels are a finite resource and at the rate we are using them, yes they will run out. but not anytime soon. but yes. we use them faster than they can be created. they WILL run out eventually.
Pollen....because cones are absent in angiosperms.....flowers are absent in gymno....and seeds are also absent in gymno sperm........so and is pollen !
