Term
Universal Solvent
Definition
Hydrophilic interactions
Hydrophobic interactions
Transport Medium
Term
High Specific Heat Capacity
Definition
Large increase in heat energy = small rise in temperature
Provides constant external environment
regulated by bodies of water
Biochemical reactions occur over a narrow temperature range
Term
High Heat of Vaporization (High B.P.)
Definition
Takes lots of heat to remove (vaporize) a little water
Sweating/panting
Transpiration
Term
Bond Angle
Definition
Solid water is less than dense than liquid water.
Ice floats
Ice insulates; pond life
Circulation of nutrients in bodies of water
(cool water sinks, hot rises)
Term
Cohesion
Definition
Water molecules stick together
Causes surface tension
Transpiration
Term
Adhesion
Definition
Water sticks to other things
Water sticks to walls of xylem during transpiration (capillary action)
meniscus
Term
Hydrophilic interactions
Definition
Water dissolves ions (like salts)
Water dissolves polar molecules (like sugars)
Term
Hydrophobic interactions
Definition
Repels nonpolar molecules (lipids); membranes
Helps determine 3-D structure of proteins and nucleic acids
Term
Transport Medium
Definition
(blood, xylem/phloem)
Term
Covalent bonds
Definition
e- are shared; strong bond
Term
Importance of Cohesion & Adhesion
Definition
From root to leaf through xylem (transpiration pull)
Organisms that live on the surface of water
Term
Water's 6 Properties
Definition
Polar-Covalent
Universal Solvent
High Specific Heat Capacity
High Heat of Vaporization
Bond Angle
Cohesion & Adhesion
Term
water forms ions
Definition
can be an acid or base
