The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0037 m. calculate the number of molecules inside th
Talja [164]

First, let calculate the volume of the rod shaped-bacteria:

S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3

Now, let's convert the moles into molecules (with Avogadro's law):

0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L

Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)

1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3

so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3

The answer is  2.22 10^ 12 molecules / µm3

Talja [164]

Answer:

The answer is NITROGENOUS WASTE.

Explanation:

The urinary tract  filters wastes and water from the blood, and eliminates them from the body.

UREA which is a nitrogenous byproduct of the decomposition of protein metabolism in mammals, is also released into the blood stream and to the tubes, after being broken down by the LIVER. All waste mixes with the filtrate to form urine

Urine is then collected in a duct and excreted through the bladder.
