Term
| Main elements used in living systems |
|
Definition
|
|
Term
| Why do living systems depend on weak interactions? |
|
Definition
| all living systems depend on water, the water can break these bonds and form new ones as needed. |
|
|
Term
|
Definition
1. Cohesion - molecules stick together via H bonds 2. High heat capacity - allows for evaporative cooling (sweat) 3. solid form is less dense than liquid - ice floats and expands due to because all ofthe hydrogen bonds are bonded to each other 4. Water dissolves polar molecules - allows for aqueous transport and diffusion within the cell 5. Water surrounds nonpolar molecules - hydrophobic effect, micelles, membranes |
