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.
The arrows usually point to the organisms that are doing the eating.
Explanation:
For that reason, we can say that the arrows represent the flow or transfer of energy in an ecosystem. It also specifies the direction of the flow of energy.
The equation is glucose+oxygen->carbon dioxide +water and energy in the form of ATP
I think the answer is Specialized cells!
Before the food handler handles any type of food or cooks and prepares them. It is best that they should properly wash their hands in order to prepare them with clean hands. It is best to wash the hands before handling the food so that the hand that could have exposed to dirt could be cleaned and it will prevent the food from being contaminated.
