Answer: D. Its tightly packed cells allow for protection against harmful substances.

Epithelial tissue is a group of epithelial cells. These tissue are found in the external surface of the body. The form the part of external skin, inner lining of the mouth, secretory glands, digestive tract, urogenital tract, lining of the organs like heart, ears, eyes, ventricular system of the brain and central canal of the spinal cord.

The cells that make up the epithelial tissue are tightly packed or are closed bound to one another. The cell layer is thick that only allows certain molecules like air, water to pass through and prevents the entry of the harmful microbes and chemical substances.

A grad student has a culture of E. coli with a total volume of 1,800 mL, and OD reading at 550 nm of 1.7. He transfers 1 mL cult

Naily [24]

Answer:

Explanation:

We'll represent the dilution as the volume transferred/total volume in the tube after transfer. So for the first dilution, 1 ml of culture was added into 9ml of broth bringing the total volume to 10 ml i.e 1/10

For the second dilution, 0.1 mL was added to 0.9mL of broth bringing the total volume to 1mL i.e 0.1/1.0 (this is also the same as 1/10). In relation to the stock culture, this is represented as 1/100 (that is 1/10 (first dilution) * 1/10 (second dilution)

Giving that the same was done for dilution 3 and 4,

third dilution is represented as: 1/10 and the fourth as 1/10 as well

In relation to the stock, dilution 3 is 1/1000

dilution 4 is 1/10000

a. the dilution in the third tube is $\frac{1}{1000} = 10^{3$ or 1.0* $10^{3}$

b. the dilution spread onto the agar plate is the fourth dilution, that is, $\frac{1}{10000} = 10^{4}$ or $1.0*10^{4}$

c. Since the grad student got 386CFU/0.2mL (200 uL = 0.2mL),

the cells in 1mL is: 386/0.2 = 1930 = 1.93 * $10^{3}$

the cells in 1800mL is therefore 1930*1800 = 3,474,000 = 3.4*10 $10^{6}$
