Green olives may be preserved in brine, which is a 20-30% salt solution. how does this method prevent contamination by microorganisms? green olives may be preserved in brine, which is a 20-30% salt solution. how does this method prevent contamination by microorganisms? high salt concentrations raise the ph, thus inhibiting the process of glycolysis. bacteria can't survive in a hypertonic solution because they lose water. high salt concentrations lower the ph, thus inhibiting the process of glycolysis. bacterial cell walls are shriveled up by salt, causing the cell to burst.

The correct answer is Bacteria can't survive in a hypertonic solution because they lose water.

The 20-30% salt solution is hypertonic as Compared to the bacterial concentration of salt. In this case, the bacteria present in the solution would lose water. Due to excess loss of water, the bacteria would eventually shrink and die. Hence, green olives preserved in the brine would be safe from microbial attack.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
