Semester 1 Final Review Sheet
Here are some concepts that were covered during Semester 1 of Pre-IB Biology. This is not a comprehensive list. Be
sure to go back through your reading guides.
Abiotic vs. Biotic factors
Community vs. population vs. individual vs. ecosystem
Water density/temperature and how this influences lake ecosystems (turn over of lakes)
Proximate vs. Ultimate questions
Fixed action pattern
Sign stimulus
Habituation
Classical vs. Operant Conditioning
Imprinting
Taxis
Kinesis
Animal communication methods
Herbivory vs. predation
Interspecific vs. Intraspecifc competition
Kin selection
Altruism
Types of dispersion
Carrying capacity
Iteroparity vs. Semalparity
k-selection vs. r-selection
Age structure diagrams
Competitive exclusion principal
Niche vs. habitat
Resource partitioning
Müllerian mimicry vs. Batesian mimicry
Cryptic coloration
Animal defenses
Symbiotic relationships (mutualism, commensalism, parasitism)
Keystone species
Primary vs. Secondary succession
Island size/distance from mainland and the effect on species diversity
Matter vs. Energy
Water/nitrogen/phosphorus/carbon cycle
Primary producers vs. primary/secondary/tertiary/quaternary consumers
Food web
Food pyramid
Autotroph vs. Heterotroph
Elements essential to life (most common elements)
Atoms (protons, neutrons, electrons)
Isotopes
Ions
Electron configuration
Covalent bonds
Ionic bonds
Types of weak bonds (see reading guide chapter 2)
Properties of water (Cohesion, adhesion, high specific heat, high heat of vaporization, polarity, etc)
Polarity of water (how this influences hydrophobic/hydrophilic nature of other molecules)
pH scale (H+ ions vs. OH- ions)
What is organic chemistry?
Macromolecules (Know what elements can be found in each, function, etc. Refer to your macromolecule matrix)
Carbohydrates
Lipid (saturated vs. unsaturated)
Proteins
primary structure, secondary structure ( helix and the
structure).
What is denaturing of a protein?
Nucleic acids
Hydrolysis vs. Condensation (dehydration) reaction
Pyrimidine vs. purines
pleated sheet), tertiary structure, quaternary
Bonding rules of nitrogenous bases (A pairs with T (or U if creating mRNA). C pairs with G)
Prokaryote vs. Eukaryote cells
Cell Organelles and their functions (See cell organelle matrix)
Plasma membrane
Function of proteins in plasma membrane
Function of carbohydrates in plasma membrane
Function of cholesterol in plasma membrane
Hypertonic, hypotonic, isotonic solution
Passive vs. Active transport
