Question 1

Question

What determines which individuals will survive and pass their traits on to the next generation?

a
commensalism
b
mutualism
c
natural selection
d
interspecies reproduction
Question 2
Which of the following would be an example of an "acquired" human characteristic, that would be heritable, as proposed by Lamarck? (Remember - he was off the mark!)

a
colorblindness
b
sickle cell anemia
c
large muscles from weight lifting
d
the presence of a tailbone in humans
Question 3
Peter and Rosemary Grant identified a new species of finch on the Galapagos Islands. This new species formed after a drought occurred on the island. How does this discovery shape our understanding in biology?

a
It shows that when environmental conditions change, populations stay the same through natural selection.
b
It shows that when environmental conditions change, populations change through use and disuse.
c
It shows that when environmental conditions change, populations change through natural selection.
d
It shows that when environmental conditions change, populations stay the same through use and disuse.
Question 4
Jean Baptiste Lamarck and Darwin varied with the process of evolution as Lamarck believed in ________, while Darwin focused on ______ for survival.

a
descent with modification, acquired traits
b
natural selection, artificial selection
c
extinction, move toward perfection
d
acquired traits, fitness
Question 5
Lamarck proposed that species change due to _______

a
use or disuse of organs or structures.
b
differences in survival rates.
c
genetic mutations.
d
competition for resources.
Question 6
Upon close examination of the skeleton of an adult python, a pelvic girdle and leg bones can be observed.

Python Slithers Closer to the Top of the TIOBE Index

These features are an example of

a
homologous structures.
b
vestigial structures.
c
comparative embryology.
d
artificial selection.
Question 7
When you have an infection, the multiplying pathogenic bacteria inside you are not all identical. Most of them are the same, but every now and again one of them will be slightly different genetically. Because of these slight genetic differences, harmful conditions, like the presence of an antibiotic, might kill most of the pathogenic bacteria, but some may be better able to survive and then thrive. These characteristics are favored in this environment, so these bacteria can continue to thrive, and make you ill. Does this scenario represent natural or artificial selection?







a
Pathogenic Breeding Pattern
b
Selective Breeding
c
Artificial Selection
d
Natural Selection
Question 8
How does natural selection lead to evolution?

a
Environmental changes kill weaker members of the species.
b
Helpful traits accumulate among surviving members of the species.
c
Stronger offspring kill weaker members of the species.
d
Overproduction provides food for stronger members of the species.
Question 9
Read the passage about punctuated equilibrium.


The theory of punctuated equilibrium states that many species did not evolve for thousands of years. Instead, evolution took place when environmental conditions shifted, causing individuals to be in more extreme competition with one another. The theory of punctuated equilibrium is supported by fossil evidence of many periods of stasis.

Which of the following statements does the theory of punctuated equilibrium challenge?

a
Evolution is a gradual process taking place in a stable environment.
b
Evolution occurs in groups of organisms through natural selection.
c
Many organisms share a common ancestor.
d
Many species remain in stasis for long periods of time.
Question 10
A balloon allows water but not sugar to pass through it. The balloon contains a 10% sugar solution. A beaker contains a 5% sugar solution. Which statement is true?

a
When placed in the beaker, the balloon will gain water by osmosis.
b
When placed in the beaker, the balloon will lose water by osmosis.
c
When placed in the beaker, the balloon will gain water by active transport.
d
When placed in the beaker, the balloon will lose water by active transport.
