Answer: 2.35 x 10^6 cfu/ml
Explanation:
Concentration of the original culture: ?
Dilution factor: 10^4
Colony count per plate: 47cfu
Volume of cultured plate: 0.2ml
Concentration of the original culture= <u>Colony count per plate x Dilution factor</u>
Volume of cultured plate
Concentration of the original culture = <u>47 x 10^4 </u>
0.2
Concentration of the original culture = 2.35 x 10^6 cfu/ml
You can further take the log of your answer which would be:
Log(2.35 x 10^6) = 6.371
Answer:
Explanation:
Calcination is a process in which ore is heated in the absence of air or air might be supplied in limited quantity. Roasting involves heating of ore lower than its melting point in the presence of air or oxygen. Calcination involves thermal decomposition of carbonate ores.
Answer:
C. Cohesion of molecules
Explanation:
Cohesion is the interaction of molecules of the same substance together. By the force of cohesion if two drops of water come together they form one. Water has high rates of cohesion due to hydrogen bonds.
This phenomenon also called surface tension and is what allows small insects to stand on water.
Cohesion along with adhesion of water to the walls of the narrow tube generate what is called capillarity. This allows liquids to ascend inside the narrow tubes. As long as the cohesion is less than the adhesion, the liquid will rise until both forces are equal.
The second answer
Temperatures up high need to be warmer near the surface, surface air needs to be humid
If you make a Punnett square, then you have all of the offspring having one dominant allele (the brown body color) and one recessive allele (the back body color).
