Answer:
Use a higher % agarose gel.
Explanation:
Agarose gels have a porous matrix. The higher the concentration of agarose, the smaller the pores, so larger DNA molecules will have more difficulty moving through the gel and they will run slower than small DNA molecules.
The higher % agarose gel has thus a better resolving power (the measurable interval between two entities -the DNA bands- is smaller). For that reason, a 2% agarose gel will allow you to differentiate better between two bands of close molecular weight, if you let the DNA fragments run long enough.
Answer: D. allopatric; breakdown
Explanation:
Allopatric speciation is a type of speciation whereby individuals of the same biological population becomes separated up to the extent that there will no longer be gene flow between them.
Weather is short period climate is over a period of years
