1. what are feedback systems in place to do?
2. list the characteristics of life.

• cellular organization
• reproduction
• metabolism
• homeostasis
• heredity
• response to stimuli
• growth and development
• cellular movement

1. are viruses alive? why or why not?
2. name something from the video that is living and something from the video that is not living.

mod b - life over time
lesson 1.1 intro to living things page 10

Explanation:

1. Feedback systems in living things help maintain homeostasis, adjusting internal conditions in response to changes. 8. The listed characteristics are fundamental to life. Cellular organization means living things are made of cells. Reproduction is the ability to produce offspring. Metabolism is the set of chemical reactions in an organism. Homeostasis is maintaining a stable internal environment. Heredity is passing on traits. Response to stimuli is reacting to the environment. Growth and development involve an increase in size and change over time. Cellular movement can be seen in some organisms. 9. Viruses are not considered alive by many because they lack cells, cannot carry out metabolism on their own, and need a host cell to reproduce. 10. Without knowledge of the video, examples of living things could be a plant or an animal, and non - living things could be a rock or a chair.

Answer:

1. Maintain homeostasis and respond to changes.
2. Cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, cellular movement.
3. No, because they lack cells, can't do metabolism independently and need a host to reproduce.
4. (Answers vary depending on the video. Example: Living - a dog; Non - living - a table)
