The correct answer is letter A
Answer:
CFU/mL
Explanation:
Given -
a) Number of colonies of bacteria is equal to
b) Total volume of the solution is equal to mL
c) Dilution factor is equal to
As we know that
CFU/mL
Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume
Substituting the given values in above equation, we get -
CFU/mL
It is the Free trade. A typical contention against free trade is the decrease of residential employments from the expansion in imported products from global nations. Free trade is exemplified by the European Economic Area and the Mercosur, which have built up open markets.
C.submarines
We use satellite and sonar today to see the ocean ridges and deep sea diving is impossible unless you have a submarine
Answer:
C) it is a polarized molecule, where the oxygen is slightly positive and the hydrogens are slightly negative.
Explanation:
The water molecule is polarized, but the oxygen atom is slightly negative and the hydrogens are slightly positive.
Electronegativity is a property that measures how much an atom will tend to attract electrons towards itself. Because electrons are negatively charged, the more electronegative an atom is, the more negative its partial charge will be.
Oxygen is much more electronegative than hydrogen, and thus it will attract the electrons in the molecule, keeping them away from the hydrogens.
