Answers
What is the order of scientific hypothesis? - ✔✔1. General Observation (GO)
2. Question (Q)
3. Learning Period (L)
4. Propose Hypothesis (H)
5. Experimental Design (E)
6. Predictions (P)
Go QL HEP
What must a hypothesis be? - ✔✔Falsifiable AND testable
What 2 things can test results do? - ✔✔1. Support hypothesis
2. Falsify-- reject hypothesis
what 2 things does an experimental design involve - ✔✔defining variables and outlining a
procedure
Dependent Variable - ✔✔what is being measured in the experiment in response to
experimental conditions
Independent Variable - ✔✔variable experimental conditions (e.g. time, temperature,
concentration, age)
Controlled Variable - ✔✔independent variables that are kept constant during the
experiment
,Level of Treatment - ✔✔Appropriate value for independent variable (HIGH amount of light
with planaria)
Replication - ✔✔Exact same procedure repeated several times
Control Treatment - ✔✔-the independent variable is set to zero or to a standard value
-Controls show whether the predicted effect is really due to the independent variable
What is a prediction? - ✔✔An If, Then statement
ie: If plants are exposed to higher light intensity, then new shoots will be produced at a higher
rate
What is the scientific name for Bean Beetle? - ✔✔Callosobruchus maculatus
What two ways can data be presented? - ✔✔Table or Figure (graph, diagram, drawing,
flowchart)
What must a table include? - ✔✔Header on top, data divided into two categories,
percentages and absolute values
Genotype - ✔✔The genetic makup or SET of alleles
Phenotype - ✔✔Determined by genetic makeup AND environment in which organism lives
Gene - ✔✔Heritable unit that may influence a trait
, Alleles - ✔✔Alternative DNA sequences at the same physical gene locus-- alternative gene
(Blue eye allele)
Homozygous - ✔✔having identical alleles for a single trait (AA or aa)
Heterozygous - ✔✔having 2 different alleles for a single trait = Aa (dominant and recessive)
Hardy Weinberg Equation - ✔✔P + Q = 1
P= frequency of dominant allele
Q= Frequency of recessive allele
P^2 + 2PQ + Q^2 = 1
P^2 = Homo Dom
Q^2 = Homo Rec
2PQ = Hetero
Natural Selection - ✔✔Heritable genetic differences passed onto next gen
What are the three types of selection? - ✔✔Stabilizing, directional, and disruptive
Modes of Natural Selection: Stabilizing - ✔✔Evolved population is above the original
population
Modes of Natural Selection: Directional - ✔✔Evolved population is the same height and to
the right of the original
