BIG IDEA 2:

BIOLOGICAL SYSTEMS UTILIZE FREE ENERGY AND MOLECULAR BUILDING BLOCKS TO GROW, TO REPRODUCE, AND TO MAINTAIN

DYNAMIC HOMEOSTASIS

Surface Area to Volume Ratio

Identify more than 4 chemical elements and molecules that function as key building blocks or are eliminated as wastes?

Discuss the consequences to organisms, populations, and ecosystems if sufficient free energy is not available.

Check out Free Energy as explained by Mr. Anderson on Bozeman Biology. (on your 0wn)

Live fast, die young. What does that mean based on metabolism and thermodynamics?

Light Dependent Light Independent

Energy in Photosynthesis

The fluid mosaic model of the cell membrane: identify all the parts and how they are related to the selective permeability of the membrane.

Internal membranes vs absence of internal membranes: eukaryotes compared to prokaryotes.

PositiveFeedback Loops

How are activities amplified?

Negative Feedback Loops

How do homeostatic mechanisms reflect common ancestry? Consider these diagrams.

How do these diagrams represent the claim that timing and coordination of physiological events in an organims involve regulation?
