a)
adaptive radiation.
b)
coevolution.
c)
punctuated equilibrium.

9.
In convergent evolution, organisms share physical similarities because they

have a common ancestor
b)
live in similar environments

develop homologous structures
d)
are closely related 
10.

11.
The flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?
a)
behavioral isolation
b)
hybrid sterility 
c)
temporal isolation
d)
mechanical isolation 
12.

According to this phylogenetic tree, which creature is the least related out of all pictured?

a)

Fish

b)

Frog

c)

Salamander

d)

Human

13.

Which group of animals on this tree are most closely related to birds?

a)

Saurischian dinosaurs

b)

Ornithischian dinosaurs

c)

Crocodiles

d)

None of these are related to birds

14.
Some salmon have adapted to be both male and female at the same time. Why would this provide an evolutionary advantage for the fish?
a)
It reduces the importance of size among salmon, allowing smaller fish to reproduce as often as larger fish.
b)
It reduces the competition between males which eliminates the need for mating rituals.
c)
It allows them to conserve energy for the rigorous swim from the ocean upstream to mate.
d)
It allows them to reproduce with any other salmon which increases the chance of mating.
15.

2pq
c)
q2

p2 + 2pq

the recessive genotype
d)
the dominant genotype

a)

.80

b)

.04

c)

.32

d)

.64
