Psych 1XX3 Midterm Exam Questions
With Correct Answers

Adaptation (evolution) - CORRECT ANSWER✔✔-A trait that helps an
| | | | | | | | |



organism survive and reproduce in its habitat
| | | | | |




Example of Adaptation (evolution) - CORRECT ANSWER✔✔-1. Raccoons
| | | | | | | |



(nocturnal) and with good vision, able to distinguish food from non food
| | | | | | | | | | |



in darkness
| |




2. Bats adapted to navigating through environment at night
| | | | | | | | |



(echolocation systems allow for descrimination between falling leaf and
| | | | | | | | |



moth fluttering)
|




Evolution by Natural Selection (evolution) - CORRECT ANSWER✔✔-
| | | | | | |



Adaptations emerge in development as a result of the activation of
| | | | | | | | | | |



relevant genes in interaction with relevant aspects of the environment
| | | | | | | | |




Natural Selection (evolution) - CORRECT ANSWER✔✔-differential
| | | | | |



survival and reproduction of organisms as a result of heritable
| | | | | | | | | |



differences between them | |

,Three components of natural selection (evolution) - CORRECT
| | | | | | | |



ANSWER✔✔-Individual Differences, Differential Reproduction, | | | |



Heritability


Individual Differences (evolution) - CORRECT ANSWER✔✔-There are
| | | | | | |



significant individual differences: within any population there is
| | | | | | | |



variation among individuals for any given characteristic
| | | | | |




Differential Reproduction (evolution) - CORRECT ANSWER✔✔-
| | | | |



Differences affect individuals' chances of surviving and reproducing.
| | | | | | | |



Some individuals will have more offspring than others.
| | | | | | |




Heritability (evolution) - CORRECT ANSWER✔✔-Traits that give rise to
| | | | | | | | |



differential reproduction have a genetic basis. Offspring of successful
| | | | | | | | |



reproducers will resemble their parents with respect to these variable
| | | | | | | | | |



characteristics.


Stabilizing Selection (evolution) - CORRECT ANSWER✔✔-selection
| | | | | |



against any sort of departure from the species-typical adaptive design
| | | | | | | | |




Darwinian Fitness (evolution) - CORRECT ANSWER✔✔-average
| | | | | |



reproductive success of a genotype relative to alternative genotypes
| | | | | | | |

, Stabilizing Selection Example (evolution) - CORRECT ANSWER✔✔-blue
| | | | | | |



would remain the most common colour in our fish population because it
| | | | | | | | | | |



is adaptive and minimizes the risk of predation
| | | | | | | |




Sexual Selection (evolution) - CORRECT ANSWER✔✔-the component of
| | | | | | | |



natural selection that acts on traits that influence an organism's ability
| | | | | | | | | | |



to obtain a mate (most organisms reproduce sexually, fusion of male
| | | | | | | | | | |



and female gametes)
| |




Sexual Selection Example (evolution) - CORRECT ANSWER✔✔-peacock
| | | | | |




- elaborate tail feathers and behaviour (must impresses)
| | | | | | |




- expensive to produce, more conspicuous to predators
| | | | | | |




- interferes with ability to escape (increases risk of dying)
| | | | | | | | |




- sheds tail at the end of breeding season
| | | | | | | |




*matter of survival and reproduction
| | | |




Darwin's Second Theory (evolution) - CORRECT ANSWER✔✔-Traits
| | | | | | |



elevate mortality and are actually being selected against in that context
| | | | | | | | | | |



but they can still evoke and become more elaborate under the
| | | | | | | | | | |



countervailing pressure of sexual selection (female mating preference)
| | | | | | |




Darwin's Second Theory Example (evolution) - CORRECT ANSWER✔✔-
| | | | | | |



Elk: Two elk (red deer) competing for dominance status the stag who
| | | | | | | | | | | |
