Taylor, a MIC 206 student needs to determine the OCD of a sample of Escherichia coli. She performed dilutions using four 9 ml di
Troyanec [42]

Answer:

1.37 x 10^6 CFU/mL

Explanation:

First, the dilution factor needs to be calculated.

Since four 9 ml dilution blanks were prepared, the dilution factor that yielded 137 colonies is of 10^{-4}.

Next is to divide the colony forming unit from the dilution by the dilution factor:

   137/10^{-4} = 137 x 10^4

In order to get the CFU/ml, divide the CFU from the dilution by the plated volume (1 mL) from the final dilution tube.

   137 x 10^4/1 = 1.37 x 10^6

Hence, the CFU/ml present in the original <em>E. coli </em> sample is 1.37 x 10^6.

cfu/ml = (no. of colonies x dilution factor) / volume of culture plate

. Explain the differences between ionic, nonpolar covalent, and polar covalent bonds.
butalik [34]

Answer:

Ionic bonds transfer ions while covalent bonds equally share them.

Explanation:

In an ionic bond, ions are transferred between each other and ionic bonds form between a metal and nonmetal.

Covalent bonds are equally shared between atoms and form between non metals only.

Specifically, nonpolar covalent bonds are perfectly symmetrical with equal distribution of electrons while polar covalent bonds are asymmetrical and there is a difference in electronegativity.

A little boy has placed his pet squirrel into a balloon with a volume of 3L at a pressure of 1.0 atm. If the boy takes his pet s
s2008m [1.1K]

Answer: The squirrel's balloon will be 0.86 L

Explanation:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.

The equation given by this law is:

P_1V_1=P_2V_2

where,

P_1\text{ and }V_1 are initial pressure and volume.

P_2\text{ and }V_2 are final pressure and volume.

We are given:

P_1=1.0atm\\V_1=3L\\P_2=3.5atm\\V_2=?

Putting values in above equation, we get:

1.0\times 3L=3.5\times V_2\\\\V_2=0.86

Thus the squirrel's balloon will be 0.86 L
