List the 8 characteristics of living things |
|
Definition
1.) Based on a Universal Genetic code (DNA,
Deoxyribonucleic Acid)
2.) Grow and Develop
Example: A human child growing into an adult
3.) Respond to their environment
Example: The sky looks dark and it looks like it will rain, so the fox goes in it's den
4.) Reproduce
Example: Two sea lions mate. Later, the mother gives birth to a baby sea lion, which eventually grows up and mates with another sea lion...continuing the cycle
5.) Homeostasis: Maintain a stable internal environment
Example: It is winter and it is extremely cold outside! However your body is still 98.6 oF/ 37 oC .
6.) Need/Create Energy
Example: A flower takes in energy from the sun and creates glucose in the process of Photosynthesis
Example: An animal eats the flower and uses it to create food to allow it to perform life functions
7.) Composed of basic units called Cells
Example: A single celled organism such as bacteria is made up of one cell. An multicelled organism such as a lynx is made up of thousands of thousands of cells
8.) Changes/Evolves over time
Example: There are many tall trees with nutricious leaves on them in the area where the giraffe lives, so over many many years, the giraffe adapts to it's environment by developing a long neck to reach these leaves
