Why is absorbance proportional to cell number in dilute suspension?
Wiki User

Because the denser the solution, the more cells are inside it. And that means also higher absorbance as the cells absorb the light. More reliable results are obtained when absorbance (optical density) measurement is conducted for dilute solutions.

What is the purpose of the energy?
Energy meter works on the same principle as the induction motor. An aluminium disc is placed inside a magnetic core with two limbs. One carries a voltage coil so its flux is proportional to voltage, the second carries a current coil so its flux is proportional to current. The two fluxes induce eddy currents into the disc, each of which interacts with the flux of the other to produce a torque, which accelerates the disc. This torque of course is proportional to flux × the eddy current, which equates to V × I, or power. A permanent magnet creates another eddy current resulting in a torque proportional to speed that brakes the disc, the combined result of these actions is that the speed of the disc is proportional to power, and the total number of revolutions is proportional to the energy that has passed through the meter. The disc drives a chain of gears that turn a mechanical counter, called a 'register'.
Does milk help dilute some poison?
Yes, but it depends on the poison. Where a poison is a corrosive, milk may limit damage to the lining of the throat and stomach, as well as absorption into the bloodstream.Contact a Poison Control Center for any ingested poison.US number : 1-800-222-1222UK number (NHS helpline): 0845 4647
How would you expect the number of mitochondria in a cell to be related to the amount of active transport it carries out?
Well, I suppose that since mitochondria are the the main production centers of ATP and Active Transport requires ATP, that these two are directly proportional. The more mitochondria a cell has, the more ATP it can make, and the more it can do Active Transport
What advantage does the streak plate method have over the pour plate method?
A disadvantage of the streak plate technique could be colony isolation problems. If the streaking technique is not done properly or if there is too much of an organism present on the inoculating loop then the cells can cluster and form what looks like one colony but it can actually be a couple colonies (made from a couple cells). This can cause an inaccurate colony forming unit count.
What is the difference between mass number and atomic number?
atomic number = number of protons mass number = number of protons + number of neutrons
Is frequency proportional to distance?
Frequency is proportional to time, the number of cycles at a certain frequency is proportional to its length(distance).
What is the pH number for dilute hydrochloric acid?
it is2000
What is the sensitivity directly proportional to in atomic emission spectrometry?
The sensitivity is directly proportional to the number of atoms in the excited state.
What is the sensitivity directly proportional to in atomic absorption spectrometry?
The sensitivity is directly proportional to the number of atoms in ground state.
Is 7 and 9 proportional?
You CAN'T determine whether two numbers are proportional, just by looking at one number from each set.
What is indirectly proportional?
"indirectly proportional" appears to be interchangeable with "inversely proportional."When a dependent variable is inversely proportional to an independent variable, that means it decreases as the dependent one increases, and vice versa. For example, a baseball player's batting average is inversely proportional to the number of at-bats. (It's directly proportional to the number of hits he gets.) In other words, as the number of at-bats increases, the player's batting average decreases. Another example is gravitational attraction between two bodies. The gravitational force between two bodies is inversely proportional to the square of the distance between them.
Is the volume of a gas directly or inversely proportional to the number of particles in a gas?
Directly proportional, at pressure and temperature constant.
What is defined as the measure of quantity proportional to the number of atoms?
weight
What is mass proportional to the number that makes up an object?
atoms
Why dilute the blood when doing red blood cell count?
We dilute the blood because in an overcrowded specimen it would be much difficult to observe the number of cells.
What is the proportional between frequency and wavelength?
Frequency and wavelength of the same wave are inversely proportional. Their product is always the same number . . . the speed of the wave.
What is opposite word for inverse?
Direct. For example, if a number is inversely proportional to something, it increase as the other one decreases. Ifa number is directly proportional to something, it increases as the other one increases.
