4. MADE UP OF CELLS
Multi-cellular
Uni-cellular

5. LIVING THINGS HAVE A METABOLISM
Main Entry: me·tab·o·lism A balance between catabolism (breaking down products) & anabolism (creating new products)

6. LIVING THINGS MUST MAINTAIN HOMEOSTASIS
Main Entry: ho·meo·sta·sis to maintain a stable state of body systems, keep a balance in health
Ex. Blood sugar, Heart rate, breathing, blood cholesterol, weight

7. Blood sugar needs to maintain a Set Point
Blood sugar needs to maintain a Set Point. Think of it as Carrying Capacity for your body
Normal value set point

8. Feedback Loops

9. Feedback Loops short video
Negative feedback loops- responds to change returning to original state, or decreasing the rate at which the change is occurring.
Trees take in CO2. As CO2 rises, they can take in more to reduce CO2 levels, CO2 level drops
Positive feedback loops- responds to change by increasing rate the change is occurring.
Ice melt in arctic-reduces reflection of heat energy, increase ice melt, increases sea level

10. Example of negative feedback Most body systems rely on negative feedbacks 4.5

13. LIVING THINGS GROW & DEVELOP

14. LIVING ORGANISMS REPRODUCE

15. LIVING ORGANISMS REPRODUCE
Main Entry: spe·cies Etymology:
Middle English, from Latin, appearance, organisms that live in the same area & can produce fertile young
MULE-
A CROSS BETWEEN A DONKEY & A HORSE
NOT A TRUE SPECIES

16. ADAPTATION 2 species of fox
