What is the difference between sample count
and total count?

A lot of researchers often perform a total count or a sample count in research. The difference between sample count  and total count is that a total count is done when the whole study area is surveyed but a sample count is done only when parts of the study area are surveyed.

The results obtained from those parts are used for the whole study area to approximately know the total population size.

Wildlife sampling methods often uses different methods of estimating animal numbers or densities. they are direct counts of population units, and indirect counts and indices.

Wild animals are very difficult to count as all  animals are never distributed evenly within the sample area and there may be fluctuations.

A sample count is the data from a sample, or a small group. A total count would be the data from the entirety of whats being studied, not just a sample.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
