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
Answer:
DNA is a long polymer with a phosphate backbone and deoxyriboses. Adenine, guanine, cytosine, and thymine are the four nitrogenous bases. The backbone of RNA is made up of ribose and phosphate. Adenine, guanine, cytosine, and uracil are four nitrogenous bases.
So DNA is two stranded, RNA is single stranded.

The linking together of many molecules of glucose may produce a molecule of STARCH
An ecosystem is a community where populations of different species interact with one another and with their non-living environment.
