biological systems interact and their interactions posses complex properties
| Question | Answer |
|---|---|
| What is cohesion? | hydrogen bonding that keeps water molecules close to eachother. Helps pull water upward in the microscopic water-conducting cells of plants, and is also responsible for water's surface tension. ( 1 of the major properties of water) |
| What is Moderation of Temperature? | Water has a high specific heat; This helps keep temperatures relatively steady, within limits that permit life; evaporative cooling is based on water's high heat vaporization & ultimately cools a surface(i.e sweating)( 1 of the major properties of water) |
| What are insulation of bodies of water by floating ice? |
