REPRODUCTION: The advantage of sexual reproduction over asexual reproduction.
What is genetic variation?
SYMBIOSIS: The type of symbiotic relationship that bees and flowers exhibit.
What is mutualism?
MACROMOLECULES: The element found in proteins and nucleic acids, but not in carbohydrates and lipids.
What is nitrogen?
CELL PROCESSES: The network of membranes and organelles that work together to make proteins and lipids.
What is the endomembrane system?
MENDELIAN GENETICS: The percent of heterozygous offspring when you cross a heterozygote x heterozygote.
What is 50%?
FIVE FINGERS: Name the 5 fingers of evolution.

What are glycerol and fatty acids?
WATER POTENTIAL: Water will flow from an area with a ___(less/more)___ negative water potential to an area with a ___(less/more) negative water potential?
What is less and more?
NON-MENDELIAN GENETICS: This type of non-Mendelian genetics results in a "blended" intermediate phenotype.
What is incomplete dominance?
SELECTION: The type of selection that selects against the phenotypic extremes and favors the intermediate.
What is stabilizing selection?

What is plasmolysis?
NONDISJUNCTION: Nondisjunction that occurs in ___(Meiosis I/Meiosis II)___ will result in more abnormalities in the gametes.
What is Meiosis I?
GENETIC DRIFT: A sharp decrease in population size due to environmental events, altering allele frequencies randomly.
What is a bottleneck event?
EUTROPHICATION: When there is an excess of ___(2 elements)___ due to agricultural nutrient runoff, eutrophication can occur.
What are nitrogen and phosphorus?
PROTEINS: Name 3 types of bonds that can form between amino acids within the same polypeptide chain in tertiary structure.
What are disulfide bonds/ionic bonds/hydrogen bonds/hydrophobic interactions?
ENDOMEMBRANE SYSTEM: Name the correct pathway to make, modify, and secrete a protein.

SPECIATION: This type of speciation occurs when a new species evolves without a physical geographic barrier.
What is sympatric speciation?
LOGISTIC GROWTH: Calculate using the logistic growth equation (WITHOUT NOTES) if the current population size is 400 insects, the carrying capacity is 500 insects, and the rmax is 0.2 insects per month. (hint: you might need to grab a calculator right now)
