Pre-AP Biology Final Exam with complete
solutions
Hypothesis
An "if, then" statement predicting the outcome of an experiment.
Independant Variable
The variable that is changed in an experiment; goes on the X-axis when graphed. (DRY MIX)
Dependant Variable
The variable that relies on the independant variable in an experiment; goes on the Y-axis when
graphed. (DRY MIX)
Constant
The variable that is not changed in an experiment.
Control
The standard variable that is used for comparison in an experiment.
Total Magnification
Ocular lense X Objective lense
Field of View
Inverse relationship; Stronger magnification makes this smaller.
10%
How much energy is transferred when an organism eats something?
Food Web
A web in which arrows point from an organism to where that organism gets its energy. 10% of the
energy is transferred.
Food Chain
The following is an example of a:
grass→grasshopper→bird
Biomass
Number of organisms X Mass of the organisms. If it is not balanced, that means it is an unstable
environment.
Predator
Reacts to the prey.
Tundra
, A cold, dry biome in which tree growth is limited by harsh temperatures. Examples of organisms that
would live in this biome are polar bears, caribou, and snowy owls.
Desert
A hot, dry biome. Examples of organisms that would live in this biome are cacti, black widows, and
some lizards.
Rainforest
A moist biome with a lot of vegetation. Examples of organisms that would live in this biome are
gorillas and tropical birds.
Savanna
A rolling grassland scattered with shrubs and isolated trees. Examples of organisms that would live in
this biome are giraffes, cheetahs, and elephants.
Enzyme
A biological catalyst that lowers the amount of activation energy needed.
Covalent Bond
A bond that is formed when electrons are shared.
Ionic Bond
A bond that is formed when electrons are transferred. It makes ions that are electrically attracted to
each other.
Hydrogen Bond
A bond that is created due to polarity.
Lipid
A macromolecule; glycerol is its monomer.
Carbohydrate
A macromolecule; monosaccharides are its monomer.
Protein
A macromolecule; amino acids are its monomer.
Nucleic Acid
A macromolecule; nucleotides are its monomer.
Cytosol
The "soup" of a cell; the fluid that makes up the bulk of a cell and surrounds the organelles.
Nucleus
