1. Biology Exams Tomorrow!
Are You Ready?

2. Safety First!

3. What is Science!!
The use of evidence to construct testable explanations and predictions of natural phenomena, as well as the knowledge generated through this process.

4. What is a Hypothesis?
Testable Predictions of a cause of solution to a problem
Not a Question!!!
Example:
If I study for my exam, then I will make a good

5. Know your Variables! D - dependent variable R - responding variableC A U S E
M- manipulating variable
I - independent variable
X- x axis
D - dependent variable
R - responding variable
Y - y axis E F C T

6. Know Your Groups!! Experiment Groups Control Groups
Contain the Independent Variable!
Do not contain the Independent Variable!

7. Know Your Biomolecules
Biomolecules Information Chart
Bio- referring to life or living things Molecule- the smallest particle of a substance composed of one or more atoms.
Biomolecules
Function
Examples
Carbohydrate
Living things use carbohydrates as the main source of energy. Carbohydrates are also used for structural purposes.
Protein
Control the rate of chemical reactions and regulate cell processes. Transport substances into and out of the cell. Form the functional parts of living things.
Lipid
Lipids are an important part of the cell’s membrane. Lipids can be used as a method to store energy for long periods of time.
Nucleic Acid
Nucleic acids store and transmit hereditary or genetic information necessary for making all proteins.

8. The Role of Enzymes
Enzymes are catalysts made of proteins. They speed up chemical reactions in cells by lowering the energy required for them to occur!
