Question 1 Choose the following scenario that is best matched to the idea of evolution by natural selection. 2% of individuals in a population die in a flood; the population remains large and there is no apparent pattern to the deaths O A group of birds grow to different sizes depending on their diet and their overall size is not heritable. A snowstorm arrives killing smaller birds. Some bears are born with long, sharp claws for digging tubers (roots) out of the ground and eating them. Claw length "runs in families" with some families exhibiting longer claws. A late spring kills off many bears with short claws A person experiences wrinkled fingertips in the water, but they are smooth when not in the water
Which of the following statements about natural selection is not true? O Natural selection operates according to differential reproductive success of individuals. O Natural selection usually predominates in small population only. O The cumulative effects of natural selection gives rise to individuals that can survive in a specific environment. O Natural selection results in evolution when individuals with higher survival and reproductive rates pass on these traits to their offspring.

Which of the following best describes natural selection? O It is a guess made by scientists about how life develops, but it has no hard evidence to support it. It is the idea that the strong survive and the weak die off. It is the idea that organisms with genetic traits that improve their ability to reproduce are more likely to pass those traits on to future generations. It is the idea that organisms naturally increase in complexity and intelligence with time.
Fred and George are arguing over evolution. Fred posits that evolution can occur in any population as long as all members gradually undergo change. George disagrees; he thinks that individual memebers of the population do not change but instead have offspring with the trait(s) of interest and thus a population evolves over generations. Who is right? Choose the best answe a. Fred is right! As members of the population respond to the environment, they change to suit it better O b. Fred is right! All memebers of the population must change aroudn the same time O c. George is right Evolution occurs over generations as only the beneficial traits are passed onto the next generation. O d. George is right! Individuals don't change their alleles, but the offspring they have contributes to the change in population allele frequencies
Question 2 Which of the following is NOT a requirement of natural selection? 1. Variation must exist between individuals in the population. 2. Variation between individuals must be transmissible to the next generation. In other words, the trait must be heritable. 3. Variation between individuals must lead to differences in survival and reproduction 4. all of the above are requirements for natural selection

Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
Four of the five factors below support the mechanism of natural selection. In contrast, the fifth factor blocks natural selection from occurring. Which one of the factors listed below does NOT lead to natural selection, but instead stops it from occurring? O Characteristics are inherited - passed from parent to offspring. O Organisms in a population are identical to each other. O There is competition among organisms in a population. O More offspring are born than can survive. O Organisms in a population vary in characteristics that affect how well they survive and reproduce. o o oO
Which of the following is true about natural selection? O It can only act on traits that are heritable and show variation. It always favors large, strong individuals. It allows species to choose what adaptations are passed on to offspring. O It acts on individual organisms, helping them become better adapted to their environment.
Which can bring new traits to a population and why? natural selection - because it increases the frequency of adaptive alleles in a population over time natural selection - because it makes new alleles natural selection and mutation because both increase the frequency of adaptive alleles in a population over time O mutation becaust makes new alleles mutation because it increases the frequency of adaptive alleles in a population over time O natural selection and mutation because both make new alleles 99+
