The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0037 m. calculate the number of molecules inside the cell, which is 4.1 μm long and 0.9 μm in diameter.

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

the answer would be b

explanation:

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
