Water Review:
A water molecules is made of:
Water is polar because
Water is considered inorganic
because
Why is water a universal solvent?
What is the difference between
cohesion and adhesion?
2 hydrogens, 1 oxygen
1 hydrogen, 2 oxygens
Hydrogen is positive. Oxygen is negative. The molecule has both positive and negative charges.
It does not contain carbon.
Water is polar and it attracted to other molecules.
Cohesion is when water sticks to itself. Adhesion is when water sticks to other stuff.
Adhesion is when water molecules to each other. Cohesion is when water molecules stick to
other stuff.
Draw and explain a hydrogen bond
What is surface tension?
Surface tension happens at the surface of water where hydrogen bonds are holding water
molecules together.
Surface tension is when water has a polar property.
Label these building blocks!!
What is the function of DNA?
Where is the nucleotide shown here?
Where are the three parts of the nucleotide?
Sugar-
Is this a molecule of DNA or RNA? Why?
PhosphateNitrogen base-
What is the function of RNA?
How is it different from DNA?
STUDY TOPICS
Water:Properties of water- polar, good solvent, stores heat, cohesion, surface tension, adhesion,
pH- measures H+ ions, acid vs. base, strong vs. weak, body fluids = neutral
Organic (contains carbon) vs. inorganic (does not contain carbon)
4 organic macromolecules: (lipids, proteins, carbohydrates, and nucleic acids)and their Structure (building block or parts) & Function ( what it does or how it is used)
Vitamins and Minerals- what they do, where they can be found
