Biologists use classification so that they can keep track of living things. This is how they are able to record information on all the many species that live on Earth.
cells which keep on changing their shape are called pleomorphic cells
Three main functions:Water dissolves chemicals that cells are in need of.It also helps keep their size and shape.Helps keep cell's temperature from changing rapidly.

Define clear criteria for categorization. Ensure categories are mutually exclusive and collectively exhaustive. Use consistent and logical classification principles. Keep the system flexible for future updates. Provide clear instructions and guidelines for users on how to classify items.
The biggest difficulty is supporting modern hardware, because the hardware keeps changing, and so the drivers must keep changing, too.
An information system requires designers and users capable of systems thinking to keep the system dynamic within an environment of constantly changing variables over time.
Carl Linnaeus was a Swedish scientist who developed the modern system of classifying and naming organisms known as binomial nomenclature. His work laid the foundation for modern taxonomy and provided a systematic way to organize and categorize the diversity of life on Earth.

In a floating exchange rate system, the rates keep on changing according to the economic conditions. The rates of the currencies are never fixed.
Modern airplanes have swept wings and so the NACA airfoil system is hard to apply since it it is constantly changing throughout the wing. Even if it was still in use, or another system is in use, the fact is that most companies keep these values extremely confidential since the wing is the most important part of a plane and they dont want other companies copying their airplanes.
