Because all animals belonging to Felidaeâs sister taxa, Viverridae, have long tails, scientists could infer that this character state represents the ancestral trait. Some domestic cats display a rosette pattern on their coats.
measurement system: The metric system of measurement. For a time, the international prototype metre and kilogram were based, for convenience, on the archive standards rather than directly on actual measurement of Earth.
The metric system, also known as the SystÃ¨me international d'unitÃ©s (SI), was developed in the late 1700s to standardize units of measurement in Europe. The metric system is the primary system of measurement used through much of the world and in science. Each type of measurement has a base unit to which prefixes are added to indicate multiples of ten. Scientific notation is a shorthand for writing very small and very large numbers.
