| Generalized Response to the environment graphs: |
|
Definition
Response on the y axis, and some sort of environmental gradient on the x-axis (ex: soil moisture).
Just know that at the extremes so low and high on the x-axis that the response is low indicating lethal. The higher the response the better the envirometn for the organism. Towards the middle of the x-axis is where reponse is highest, then it decreases again as it gets higher and higher.
It goes lethal, survival, growth and reproduction, survival, lethal. For the responses. |

| important properties of water: |
|
Definition
High specific heat: resits changes in temperature and in state.
Cohesion: Due to H-bonding, allows for surface tension. creating a film. Water sticks together.
Adhesion: water ability to stick to surfaces.
