Chemistry of Life
Explain what property of water allows substances to dissolve in it
Uneven charge distribution
Explain the structure and function of the ER
rough ER- synthesize proteins, ribosomes bound to membrane folds
smooth ER- synthesize lipids for membranes
Explain Independent Assortment
Each pair of alleles segregates into gametes independently, however this is only true for genes located on different chromosomes.
Explain Hardy-Weinberg Equilibrium
p+q=1
p2+2pq+q2=1
Explain what property of water allows organisms to maintain an optimal temperature.
High specific heat.
Explain the how cells regulate what moves in and out
Plasma membrane is semi-permeable; small molecules dissolve through and large polar molecules travel through protein channels
Explain co-dominance and incomplete dominance
Co-dominance: two alleles are expressed individually
Incomplete dominance: two alleles are expressed as a fusion of both
Explain Fixed Action Patterns
sequence of behaviors that must be completed once initiated
Draw the functional group that determines amino acid’s polarity
hydroxyl group
Draw and label both energy producing organelles.
Mitochondria- double membrane with Cristae
Chloroplast- membrous sacs with thylakoid stacks
Draw a punnet square for a AaBB/ AABb cross
AABB- 4
AABb- 4
aABB- 4
aABb- 4
Draw a food web and label each tropic level
Producers (heterotrophs)
Primary consumers
Secondary consumers
Tertiary consumers
Act out the process by which macromolecule bonds are broken
Hydrolysis
Act out the process of protein folding.
Primary- amino acids sequence
Secondary- local folding
Tertiary- global folding
Quaternary- different polypeptide chains assemble
Act out the event during meiosis that is responsible for genetically diverse offspring in sexually producing organisms
Crossing over- sister chromatids intertwine and exchange sections of DNA
Act out altruistic behavior and agonist if behavior
altruistic behavior- acting in the interest of another organism
agonistic behavior- competing with other organisms
