Biology Lab Final sheets #1
Quiz #1 out of 4.
tentative explanation, proposed testable answer on the scientific question
response to the experimental conditions which investigator measures, counts, or records.
what the investigator varies in the experiment
level of treatment
appropiate values to use for the independent variable
part of the experiment where the independent variable is removed or set at standard value
(An investigator studies the amount of alcohol produced by yeast when it is incubated with different types of sugars) Dependent Variable?
amount of produced alcohol
(An investigator studies the amount of alcohol produced by yeast when it is incubated with different types of sugars) Independent Variable?
Incubation with different types of sugars
(An investigator studies the amount of alcohol produced by yeast when it is incubated with different types of sugars) Controlled Variable?
type of yeast, the conditions of incubation, method of alcohol level measurement

molecule which differs from the normal molecule by its three dimensional structure but has same molecular formula
part of molecules that when attached to hydrocarbons modify their chemical and physical properties
Difference between carbonyl aldehyde and carbonyl ketone functional groups
one hydrogen atom. In aldehyde it bonds to the end but in ketone it bonds inside the carbon chain
hydroxyl functional group
Functional group carried by an alcohol molecule
carboxyl functional group
functional group carried by organic acid molecule
product reaction between organic acids and alcohols
functional group carried by mercaptans
Hydroxyl and Carbonyl groups
functional groups included in carbs molecules
condensation reaction between two amino acids. The hydrogen atom on the amino group of one amino acid reacts with the hydroxyl group on the carboxyl group of another.
3 components of the nucleotide
phosphate group, five carbon sugar and a nitrogen base.
