BSC 196 Final Exam Study Guide Exam
Questions With Correct Answers
random mating - CORRECT ANSWER✔✔-Not a requirement of evolution
| | | | | | | |
by natural selection
| | |
natural selection - CORRECT ANSWER✔✔-leads to adaptations
| | | | | |
homology - CORRECT ANSWER✔✔-Structural similarities within
| | | | | |
different species |
Common origin of all life on Earth - CORRECT ANSWER✔✔-All organisms
| | | | | | | | | |
use essentially the same genetic code.
| | | | | |
intrasexual selection - CORRECT ANSWER✔✔-In elephant seals, males
| | | | | | | |
fight by slamming their upper bodies together and biting each other on
| | | | | | | | | | | |
the neck. 'Losers' give way to 'winners' in subsequent interactions.
| | | | | | | | | |
Consequently, males winning the most fights usually obtain the most
| | | | | | | | | |
copulations. This breeding system best illustrates the concept of:
| | | | | | | |
stabilizing selection - CORRECT ANSWER✔✔-Selection which favors
| | | | | | |
individuals that exhibit an intermediate value of a trait
| | | | | | | |
,strong natural selection - CORRECT ANSWER✔✔-Causes a population to
| | | | | | | |
deviate from a Hardy-Weinberg equilibrium
| | | | |
Vicariance event - CORRECT ANSWER✔✔-Geographic separation of
| | | | | | |
population, typically something physical, such as a mountain range or
| | | | | | | | | |
glaciation
habitat isolation - CORRECT ANSWER✔✔-2 species live in the same area
| | | | | | | | | |
but different habitats
| | |
Sympatry - CORRECT ANSWER✔✔-Zones occurring in the same
| | | | | | | |
geographical area |
Allopatry - CORRECT ANSWER✔✔-not occuring in the same
| | | | | | | |
geographical area |
behavioral reproductive isolating mechanism - CORRECT ANSWER✔✔-
| | | | | |
What role does reinforcement play in the speciation process? -
| | | | | | | | | |
CORRECT ANSWER✔✔-it promotes reproductive isolation among
| | | | | |
populations that were previously separated, but the have recently come
| | | | | | | | |
into secondary contact
| | |
, what is an example of a postzygotic isolating mechanism? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-hybrid sterility |
what is a important mode of speciation in plants? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-allopolyploidy
What is a characteristic of allopatric speciation? - CORRECT
| | | | | | | | |
ANSWER✔✔-geographic barriers to gene flow | | | |
How were the conditions on Earth more than 3 billion years ago differ
| | | | | | | | | | | | |
from those today, - CORRECT ANSWER✔✔-Unlike Earth today, early
| | | | | | | | |
Earth had an atmosphere rich in gases released from volcanic eruptions
| | | | | | | | | |
Why is RNA believed to be the first genetic material? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-RNA has the capacity for both replication and energy | | | | | | | | |
processing (catalytic property) | |
Where are the oldest fossils usually found? - CORRECT ANSWER✔✔-In
| | | | | | | | | |
the deepest strata
| |
Endosymbiosis - CORRECT ANSWER✔✔-As Earth was becoming more | | | | | | | |
aerobic, mitochondria would have provided an advantage to host cells
| | | | | | | | | |
by converting "toxic" oxygen into energy for
| | | | | |
