Water has this property based on uneven sharing between hydrogen and oxygen
What is polarity?
A material composed of two or more elements or compounds
What is Carbon?
This is a polysaccharide found in animal cells
What is glycogen?
These are biological catalysts
What are enzymes
Cohesion in water is a result of the formation of these
What is Hydrogen bonding?
Blood is an example of this
What is a suspension?
Carbon has this number of valence electrons
What is four?
This property of phospholipids make it an excellent material for the cell membrane.
What is a polar head group and a hydrophobic tail?
What is they denature?
Water moves from the root to the leaves due to this
What is capillary action?
The scale that is used to describe the concentration of hydrogen ions in solution
What is the pH Scale?

What is the sugar, base and phosphate group?
This test is used to determine whether monosaccharides are present
What is the Benedict's test
Large bodies of water, such as oceans and lakes, can absorb large amounts of heat with only small changes in temperature. This occurs due to this property of water.

An unsaturated lipid contains these
What are double or triple bonds?
This test is used to determine whether proteins are present
What is the Biuret reagent?
Water is often called this because it can dissolve many ionic compounds and polar molecules.
