10 ng is the minimum amount of DNA to visualize it on agarose gel. The amount of DNA to load per well is variable. The least amount of DNA that can be detected with ethidum bromide is 10 ng.
Water is better solvent for salt as compared to oil because water is a polar solvent. The water molecules are tend to attract each other and other polar molecules also because of their polarity. The oil molecules are non polar hence, they will not attract to any other polar molecules. Therefore, water is a better solvent for salt as compared to oil.
In this virtual lab, grow two species of paremecium in test tubes and record data on their population growth. Experiment shows that when grown together, one species will die, illustrating the competitive exclusion principle.
I say B it makes the most sense
Answer:
causes a cell to swell-isotonic solution
doesn't change the shape of the cell-isotonic solution
causs the cell to shrink-hypertonic solution
Explanation:
The hypotonic solution causes a cell to swell since the hypotonic solution has a lower concentration than the cytoplasm of the cell the water enters the cell through osmosis.
The isotonic solution doesn't change the shape of the cell since it has roughly the same concentration as the cell's cytoplasm
The hypertonic solution causes the cell to shrink since it has a higher concentration than the inside of the cell the cell loses water
