It is because the six-kingdom is more like newer and every time a new part of a kingdom is discoverd someone uses it and then scientists use it more and more.So then they use it until they find a better one but they still use the previewes ones.
Some scientists use a six-kingdom system to include a separate kingdom for archaebacteria, which are prokaryotic organisms with distinct genetic and biochemical characteristics different from bacteria. This system provides a more accurate representation of evolutionary relationships among different organisms compared to the five-kingdom system, which lumps archaebacteria with bacteria in the same kingdom.
Most scientists accept the traditional five-kingdom classification system, which includes the kingdoms of Animalia, Plantae, Fungi, Protista, and Monera. However, some scientists now prefer the three-domain system, which categorizes organisms into Bacteria, Archaea, and Eukarya.
Scientists use a classification system called taxonomy to categorize plants and animals based on their shared characteristics. This system groups organisms into hierarchical categories like kingdom, phylum, class, order, family, genus, and species. By classifying organisms in this way, scientists can better understand their relationships, evolutionary history, and biological characteristics.
International System of Units (SI)
Metric system simply refers to a system of measurement in which the values are decimalized (i.e. one unit differs from another by a power of 10). The metric system commonly used in the world today is referred to by many scientists as "SI" which is short for Systeme International d'Unites, French for International System of Units.
Taxonomy is important because it helps scientists to organize and classify organisms based on their similarities and differences, providing a framework for understanding evolutionary relationships. This classification system allows for easier communication among scientists and provides a basis for further research into biodiversity and the natural world.
SI system is used by scientists. It is one of the standard system adopted by scientists.
Scientists use the metric or SI units of measurement.
Scientists in all countries use the metric system.
Animal testing is to find out how medicines work and how they help or don't help. Instead of using people for this system they use animals. Animal testing is to find out how medicines work and how they help or don't help. Instead of using people for this system they use animals.
The scientists use classification system to make things easier and less complex.

Scientists use the System Internationale - the international system of units. This is a metric system. Most countries have switched to the metric system for everyday ie in shops and in the kitchen.
