3
$100 Question Water is polar. What does this mean? Because water is very polar, it is the universal _____
4
$100 Answer Water molecules have 2 hydrogen atoms and 1 oxygen atom. Polarity means a clear positive end and negative end. Solvent
5
$200 Question Water is cohesive. What does this mean? Give an example of how this helps organisms.
6
$200 Answer Water molecules are attracted to each other. This causes surface tension and water droplets on waxy leaves
7
$300 Question Water is adhesive. What does this mean? Give an example of how this helps organisms.
8
$300 Answer Water molecules can be attracted to certain surfaces. This allows capillary action
9
$400 Question Water is _____ dense as a solid. What does this mean? Give an example of how this helps organisms.
10
$400 Answer Ice floats instead of sinking. This prevents flooding, and allows for lakes to remain only partially frozen in winter.
11
$500 Question What property of water does each example belong to? -meniscus -ice floating -water traveling from the roots of a plant up to the leaves -water droplets on a waxy leaf
12
$500 Answer -meniscus: ADHESION -ice floating: H2o LESS DENSE AS SOLID -water traveling from the roots of a plant up to the leaves: ADHESION -a bug sitting on the surface of H2O: COHESION
13

25
$200 Question What are the building blocks of lipids? Hint: composed of glycerol and 3 fatty acids
26
$200 Answer Triglycerides
27
$300 Question Lipids are non-polar. What does this mean?
28
$300 Answer No clear positive or negative end. Not soluble in water; will not mix
29
$400 Question What is the function of lipids?
30
$400 Answer Lipids STORE energy
31
$500 Question What elements are found in lipids?
32
$500 Answer C H Carbon and hydrogen. The energy is stored in the bonds between these atoms. Energy released when bonds break
33
