Life
What are the 6 kingdoms of Life?
Eubacteria, Archaebacteria, Protista, Fungi, Plantae, Animalia
Define the following: Prokaryote, Eukaryote, Autotroph, Heterotroph
Prokaryotes: No Nucleus| Eukaryotes: Nucleus
Autotroph: Produce their own energy
Heterotroph: Eat other organisms for energy
What is a polar molecule?
To have two different charges atoms making upo the molecule (Ex: Water | (o-)-(H+)-(o-)
They bind to substrates
Identify the 7 characteristics of Life.
Reproduction, Homeostasis, Cellular Organization, Metabolism, Heredity, Responsiveness, Grow and Develop
List the organization of living things from simplest to most complex, starting with cells
Cells -> Tissue -> Organs -> Organ Systems -> Organisms
Is a virus Alive? Why?
No! it does NOT have a metabolism, one of the characteristics of life
What properties of water make it important for living things?

The acidity of something
Define the following:
Dependent Variable
Independent Variable
Control
Hypothesis
The thing being measured
The thing being manipulated

What is the genetic difference between Asexual and Sexual Reproduction?
Asexual reproduction; the clone is the same DNA as the one parent
Sexual reproduction; the kid is 50% DNA of the dad and 50% of the mom

What are the 4 characteristics used to Classify Organisms into Kingdoms?
Cell type, Cell Structure, Body Type, and Nutrition
What are the differences between the three different types of bonding?
Ionic: Two different charged atoms
Covalent: Share an Electron
Hydrogen: Weakest bond, bonds to oxygen
What is activation energy?
The amount of energy required to start a chemical reaction
