Cell Membrane pump works to regulate the Sodium and Potassium. The channel will open and allow Sodium in while releasing Potassium.
33% is the unknown concentration of the tube.
Explanation:
Concentration of stock of windex = 50%
concentration of bacteria = 500 microliter
nutrient broth = 1000 micro litre +500 microlitre of windex
concentration of bacteria is the volume of bacteria present in nutrient broth culture.
total volume in the tube is 1000
50% is the concentration of tube of bacteria and broth before adding windex.
After adding windex of 50 % concentration and the volume is 500 microliter which is only 250 microliter of windex rest is water.
33% is the concentration of the tube, which means it has 33% of bacteria in 1500 ml of solution.
D Because supports large numbers of plants and species and variety of crops
The rungs are composed of hydrogen bonded paired Nitrogenous Bases. These pairings are Adenine to Thymine and Guanine to Cytosine.
