Multiple and sub-multiples are used when the range of values is too large to be measured in a single unit.
these are used to express very large number small and very small
The standard for science the world over is the metric system, and most commonly the mks system of units. This stands for meter, kilogram, seconds. Different sub-fields may use slightly tweeked units like the cgs system which stands for centimeter, gram, seconds but these are still metric units.
Without knowing the specific subject or sub-category of that subject it is not possible to give a numeric answer.There are several systems of measurement each with different standard units. The most commonly used is the SI system, however, all rely on defined units and others that are derivedfrom these.Defined units would be for such things as mass, length and time.Derived units would be area, volume and speed.These are only examples.There are also units with no physical quantity which are used in certain areas which are purely comparative.An example would be a persons IQ for instance
In (Simple) random sampling, all of the units in the sample have the same chance of being included in the sample. Units are selected randomly from a population by some random method that gives equal probability to each element. In stratified random sampling, the entire population is divided into heterogeneous sub-popuation known as strata (sub-population with unequal variances) and a random sample is chosen from each of these stratum. The reason when to use which depends on the situation and need of the experimenter.
Some sub-areas or sub-branches of geology include mineralogy (study of minerals), petrology (study of rocks), sedimentology (study of sedimentary rocks), structural geology (study of rock deformation and tectonics), and geochemistry (study of the chemical composition of rocks).
Proteins provide building blocks for the structural components of organisms.
mineralogy
India is called the sub-continent. Historically (geology) it was its own continent before colliding with Asia.
Sugars
The population of Canadian Sub-Surface is 300.
Canadian Sub-Surface was created in 2004.
The population of Canadian Sub-Surface is 2,005.
Structural.
amino acids :)
Nucleotides
No, fatty acids are not sub-units of carbohydrates. Fatty acids are components of lipids, while carbohydrates are composed of sugar molecules like glucose.
