Which of the following units is the most often used to express the size of microbes?

Answer 1

Optical microscopes typically examine things that can be measured in microns, (=micrometers); electron microscopes, which can image viruses, might use nanometers, which are 1,000 to the micron. Objects not normally seen, such as atoms and atomic nucleii, can be described in term of picometers, femtometers and attometers, which are a million, a billion and a trillion to the micron, respectively.

There is an older unit, the Anstrom, which is ten thousand to the micron.

Answer 2

you usually use the picometer or the nanometer.

ANSWERGenerally in Science, you would use the Metric system of measurement.

Therefore, when talking about cells and microscopic organisms, you would be measuring using MICROMETRE (abbreviated: µ --micron ) or stated as: µm (micro metre).

Micrometre is 1 millionth of a meter, 1 thousandths of a milimeter (mm), or 1 x 10-6 meters

To give you the idea of how small a micro metre is, a human hair is about 100 µm, wide, and a red blood cell would be around 8 µm wide, the typical size of an animal cell would be from 10 - 100 µm

Answer 3

Micrometers (μm) is the most often used unit to express the size of microbes because microbes are typically very small and measured in micrometers.

Answer 4

using micrometer. 1 micrometer = 0.001 millimeter

Answer 5

the abreviated form is nm i think.

Answer 6

I would use micrometers.

Answer 8

Micrometres or nanometres.

Answer 9

Microns.

Answer 10

nanometers
