closest to zero
closest to 1
2

300
150
75
175
6
Which of the following is NOT an abiotic factor?
water
temperature
decomposers
air
7
According to the differences in the number of amino acids, who is the most distant common ancestor?
B
A
C
D
8
What is the growth rate?
Growth Rate (r) = Birth rate – Death rate
Growth Rate (r) = Birth rate + Death rate / Population
Growth Rate (r) = Death rate + Birth rate
Growth Rate (r) = Birth rate – Death rate/ Population
9
Innate, highly stereotypic behavior that must continue until it is completed
classical conditioning
Fixed action pattern
imprinting
associative learning
10
Which of these would most likely result in a population NOT in Hardy-Weinberg equilibrium ?
sexual selection
large population
no gene flow
random mating
11
Which species is most distantly related to humans based on the amino acid differences?
chimpanzee
gorilla
horse
rhesus monkey
12
Which of the following categories of animal behavior describes ducklings following their mother
Fixed action pattern
classical conditioning
imprinting
associative learning
13
Which of the following is a density-independent factor limiting human population?
competition for food
naturally occurring fires
famine
disease
14
Different species may be prevented from interbreeding by responding to different mating dances
gametic isolation
hybrid sterility
mechanical isolation
behavioral isolation
15
Which letter shows a mature, well-established population in favorable conditions, with equal birth/death rates?
C
A
B
16
Which has the highest Simpson's diversity?
Not enough info
A
They are the same
B
17
Which best describes a K-strategist?
Frogs
Songbirds

18
Which letter shows a population at it's carrying capacity?
C
B
A
19
Similar structures of the same embryonic origin are called
analogous structures
pseudo structures
homologous structures
vestigial organs
20
Which best describes an organism that would be a pioneer species during primary succession?
Type I
Type II
Type III
21
All of these are parts of Darwin's theory EXCEPT
natural variation
survival of the fittest
inheritance of acquired traits
overpopulation
22
According to the differences in the number of amino acids, who is the most closely related?
D & E
A & B
B & C
C & D
23
How would the population of ants change if the tarantula population decreased?
Decrease
Increase
No change
24
According to this cladogram, what organism (most ancestral) is the outgroup from the vertebrate organisms?
lungfish
lungs
birds
lobsters
25
Which of the following is a measure of an organism's fitness?
How quickly it matures
ability to withstand environmental extremes
how strong it is when competing with others for food
number of fertile offspring it produces
26
Why do bacteria become resistant to antibiotics?
antibiotics cause mutations in bacteria
resistant bacteria survive and reproduce
bacteria get used to antibiotics and they have less effect
humans become resistant to antibiotics not bacteria
27

2
represents
homozygous dominant individuals
homozygous recessive individuals
Dominant allele
Recessive allele
28
Any inherited characteristic that increases an organism's chance of survival
adaptation
vestigial organs
fitness
29

the varied nutrient supplies in the area
interactions among individuals in the population
chance
random distribution of seeds

parasitism
mutualism
commensalism
predation
33
During the Industrial Revolution, what happened to the peppered moth population?
White moths changed their color to blend in with trees
dark moths decreased & were not as fit as peppered moths, which increased.
All the moths died from pollution
