What is the difference between being warmblooded and cold blooded?
Cold Blooded means their body temperature is the same as their environment.
Warm Blooded means their body temperature is maintained at a particular temperature, no matter where they are.

When scientists classify living things, are they using physical characteristics?

When scientists classify living things, are they using physical characteristics?
No! They are using structural characteristicsthings that stay the same throughout the adult life of a living thing.
For example:
In animals: bone structure, the circulatory system, and the reproductive system.
In plants: seed production, ways of transporting minerals and nutrients inside the plant, root systems.
