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:
Explanation:
In scientific measurement,
Accuracy refers to the closeness of a measured value to a standard or specific value while precision is the level of agreement of a particular measurement with the measured value it is repeated.
B-monomer
I am not sure about the second one but i think it's C
The Sympathetic Nervous System is a part of the Autonomic Nervous System which has sympathetic neurons found on the spinal cord. This activates the fight or flight response. Once the neurons are released binding of adrenergic receptors happened thus the effects are seen on the body such as increased sweating,high rate,blood pressure and pupil dilation.
