BIO UNIT 1 QUESTIONS

water’s unique property

hydrogen bonding

amino acids effect tertiary structure of proteins

interactions of different R groups together & with their enviorment

spirogyra submerged

lacking nitrogen.. so no change in carbs and lipids, but LESS of proteins and nucleic acids

adding of water vs taking out water

hydrolysis vs dehydration synthesis

how water travels through xylem cells

both are polar - hydrogen bonding with each other & the walls of the xylem cells

peptide bond

specific type of covalent bond

feature of organic compounds NOT found in inorganic compounds

covalent bonding of carbon atoms

amino acids interacting with lipid tails are ______

hydrophobic

dependent variable in algae study

concentration of chlorophyll a

chemical binds to a protein & prevents formation of an alpha helix.. which structure is affected?

secondary structure affected only

structural difference between RNA and DNA

DNA = deoxyribose sugar RNA = ribose sugar

dipeptide & amino acid binding

central carbon should bind to hydrogen ion

30% adenine in RNA… what % is Thymine

0% - no thymine in RNA

Cholinesterase catalyzes hydrolysis

breaks down covalent bonds by adding water

carbon cycle goldfish experiment - whats the best type of graph

bar graph

bacteriophages most likely to release:

DNA

FRQ Fly catchers: 1 independent variable, 1 dependent variable, 1 negative control

IV = bird models from each of the two populations DV: aggression score NC: Golden whistler group
