Why is the structure/order of proteins important?
A change in structure causes a change in the function
The order of proteins is not important
The order determines the effectiveness of the protein
The structure of proteins determines the structure of carbohydrates

Over winter break, Karter's teacher asked the class to find an example of a property of water, take a picture, and write about it. Karter and his family visited their lake house and Karter noticed the lake had froze over. What property is Karter observing?
Ice is less dense than water.
Surface tension allows the ice to freeze.
Capillarity action allowed the ice to travel to the surface of the lake.
High heat capacity allowed the ice to form on the surface of the lake.
In completing a stations lab, Trinity noticed at Station 1 that water droplets had collected on a leaf. She was told to write down the water properties she observed. Which properties should Trinity check off?
adhesion and surface tension
cohesion and capillary action
surface tension and cohesion
adhesion and cohesion
