Quiz 11

Question 1

1. Compared to other developed countries, where did the United States rank when it’s citizens were asked if they thought that humans evolved from other species of animals?
   at the top (majority accept that humans evolved from other animals)
   in the middle (about 50% accept that humans evolved from other animals
   at the bottom (a minority accept that humans evolved from other animals

Answer 1

at the bottom (a minority accept that humans evolved from other animals

Question 2

2. Natural selection is the process component of the theory of evolution and descent with modification is the pattern component
   true
   false

Answer 2

True

Question 3

3.  The evolution of lactose tolerance in two different human groups is an example of: 
unequal crossing over 
gene duplication
non-disjunction
convergent evolution

Answer 3

convergent evolution

Question 4

4. Which of the following pairs of structures are homologous with one another?
   a bird wing and an insect wing
   a bat wing and a human arm
   a dolphin dorsal fin and a dorsal fin of a shark

Answer 4

a bat wing and a human arm

Question 5

5. The DNA sequence of the human cytochrome c oxidase gene is more similar to the DNA sequence in a pig compared to the cytochrome c oxidase gene in a fish. This is because:
   mammals require a similar cytochrome c oxidase gene relative to fish
   humans and pigs share a more recent common ancestor than either does with a fish
   the similarity between human and pig cytochrome c oxidase genes is due to chance
   the similarity between human and pig cytochrome c oxidase genes is due to convergent evolution

Answer 5

humans and pigs share a more recent common ancestor than either does with a fish

Question 6

6. Which of the following statements about the meaning and implications of the “great chain of being” is NOT correct?
   a ladder-like hierarchy of non-living and living things
   species were capable of changing
   species were created by God

Answer 6

species were capable of changing

Question 7

7. According to Darwin, the plants and animals found on the Galapagos islands were most similar to those:
   found on other tropical island archipelagos he had visited
   found in Africa
   found in South America
   found in Europe

Answer 7

found in South America

Question 8

8.  Natural selection acts on \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, but \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ evolve
genotypes, phenotypes
phenotypes, individuals
populations, individuals 
individuals, populations

Answer 8

individuals, populations

Question 9

9.  The ability of an individual to pass on its alleles to offspring relative to other individuals in the population is referred to as:
adaptation
natural selection
fitness
convergent evolution

Answer 9

fitness

Question 10

10. Two scientific criticisms of Darwin’s theory of evolution were put forth shortly after Darwin’s proposed descent with modification as a result of natural selection to explain how life evolved.  One criticism had to do with blending inheritance, and the other involved? 
how genes passed on genetic information
the age of the Earth
Biblical accounts of the creation
difficulties observing speciation

Answer 10

the age of the Earth

Question 11

11. How would it be possible to have a daughter with a X-linked trait?
    the father had the trait and the mother did not
    the mother had the trait and the father did not
    the father had the trait and the mother was heterozygous for the trait

Answer 11

the father had the trait and the mother was heterozygous for the trait

Question 12

12.  In terms of possible phenotypes, multi-genic traits typically approximate:
a 9:3:3:1 ratio 
a 2:1 ratio as in blending inheritance
a 3:1 ratio
a 9:16:3:3:1 ratio
a bell-shaped curve

Answer 12

a bell-shaped curve

Question 13

13.  Suppose a man with type A blood marries a woman with type B blood.  The first child they have has blood type AB.  If they were to have more children what other blood types are possible?
only blood type AB is possible
A or B
A, B or O
O

Answer 13

A, B or O

Question 14

14. Why were fossils problematic for those who believed that God specially created every living species found on Earth?
    Fossil organisms represent life forms that have gone extinct, but God was supposed to create perfection
    Fossils typically do not represent extinct organisms, so there is no problem
    The presence of fossils meant that the Earth was much older than Lord Kelvin estimated

Answer 14

Fossil organisms represent life forms that have gone extinct, but God was supposed to create perfection

Question 15

15. When Geologists examine strata (layers of rock), the deeper strata are:
less complex
older
more complex
younger

Answer 15

older
