- 1. Multiple ChoiceWhy are advantageous traits more likely to be passed onto offspring?Because they are more likely to survive and reproduce.Because they come from dominant alleles.Because they come from recessive alleles.Because the trait is an acquired phenotype.
- 2. Multiple ChoiceWhat is the advantage of having different shaped beaks?To look different from other species.To be able to eat the food readily available in the environment.To protect itself against predators.To protect itself against prey.
- 3. Multiple ChoiceA fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?This is purely by chance and isn't significantThe extinct dinosaur and modern bird share a common ancestorAll dinosaurs evolved into birds and that's why there aren't any dinosaurs alive todayDinosaurs choose to fly, and evolved into birds to escape predation and capture food
- 4. Multiple Choice
Any change in an organism that allows it to survive and reproduce more effectively in its environment
natural selection
adaptation
evolution
population
- 5. Multiple Choice
What is natural selection?
Sharp reduction in population size due to an environmental disaster, often results in loss of variation
When individuals survive and reproduce at a higher rate than others in the same population due to some environmental pressure
Process by which populations have become adapted to their environment over time
Specialized structures and behaviors that aid in survival
- 6. Multiple Choice
What are adaptations?
Sharp reduction in population size due to an environmental disaster, often results in loss of variation
When individuals survive and reproduce at a higher rate than others in the same population
Process by which populations have become adapted to their environment over time
Specialized structures and behaviors that benefit the organism and aid in survival
- 7. Multiple ChoiceIf an organism has a vestigial structure, that structure likely once had a function in a(n)close relativeearly ancestorunrelated organismembryological stage
- 8. Multiple ChoiceOn the cladogram, which organism is the closest relative of the human?FrogHareCaimanParrot
- 9. Multiple ChoiceIndividuals that are well adapted to their environment will survive and produce:Fewer mutationsStronger genesMore offspringBetter traits
- 10. Multiple ChoiceOn this map there are many different geographical barriers, which could be mountains, rivers, or oceans. Animals that do not have a barrier between them have more similarities, which set shows that common ancestry existed?1 and 23 and 47 and 8
- 11. Multiple ChoiceWhat type of evolution do homologous structures show?convergentdivergentartificial selectiondisruptive selection
- 12. Multiple Choice
There are species of lizards that burrow underground. Gophers and moles are mammals that also burrow underground.
allopatric speciation
divergent evolution
convergent evolution
coevolution
sympatric speciation
- 13. Multiple Choicea measure of how commonly a particular allele occurs in a population is known as thegene poolallele frequencymutation ratephenotype
- 14. Multiple ChoiceMutations are important because they bring aboutdeath of the organism in which they developgenetic variation needed for a population to evolvebenefits for the individual, not for the populationHardey-Weinberg equilibrium within a population
- 15. Multiple ChoiceThe table shows the survival rate of two types of beetles in the same environment over a period of three years.
Which statement about the beetles in this environment is best supported by the data?Brown beetles have a shorter life cycle than green beetles haveGreen beetles are more fit for their environment than brown beetlesbrown beetles are undergo more unfavorable mutations than green beetles - 16. Multiple ChoiceSome animals are able to see in ultraviolet (UV) light. Bees for instance can see Green and Blue and UV, but no Red, but butterflies and birds can see Red, Green, Blue and UV. Why would a plant need these special ultra violet markings?to show insects they are poisonousAttract insects to help it pollinateavoid sunlightvisibility at night
- 17. Multiple ChoiceDogs are closely related to wolves. To prove this, what type of testing or experiment would a scientist most likely carry out?compare wolf and dog DNAexamine their social habits and record similaritiesfeed them similar foods and see if they have similar dietsdetermine whether a female dog will care for a wolf pup
- 18. Multiple ChoiceThe Asian shore crab invaded parts of the eastern coast of the United States about 15 years ago. The Asian shore crab preys on blue mussels. In the time since the Asian shore crab arrived, the average shell thickness of the blue mussel population has increased. Which of the following is the most likely reason that this increase in shell thickness has occurred?Blue mussels with thick shells attract more crabs that mussels without thick shells.Blue mussels with thick shells grow in larger colonies than mussels without thick shells.Blue mussels with thick shells catch more food per day than mussels without thick shells.Blue mussels with thick shells survive and reproduce more successfully than mussels without thick shells.
- 19. Multiple ChoiceIn recent years "SuperBugs" (bacteria that aren't effected by antibiotics) are becoming more and more common. How could natural selection explain this?Superbugs survive antibiotics and reproduceAntibiotics cause bacteria to become superbugsWe have always had the same amount of superbugs; modern media just discusses them more.There is no reliable data on the origin of super bugs.
- 20. Multiple ChoiceWhy would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?Individuals will only create offspring well-suited to the climate changeThe individuals would produce more offspringIndividuals better suited to the new climate will help less-suited individuals surviveSome individuals will posses traits better suited to the new climate and be more likely to pass them on
- 21. Multiple ChoiceCrossing over is important because....It prevents mutations from entering the gametes.It allows for even distribution of chromosomes in the gametes.It allows for more genetic diversity of gametes.It allows for genetic uniformity of gametes.
- 22. Multiple ChoiceSince the 1800s humans have stopped burning coal, and the trees have returned to their original color. Which moth will be more successful in this environment?Dark mothLight mothBoth will be equally successfulNeither will be successful
- 23. Multiple ChoiceWhy is the mouse population changing over time?The light mice can reproduce more successfully than the dark miceThe hawks eat more dark mice than light mice because the dark mice taste betterThe hawks eat more light mice than dark mice because they can see the light mice more easilyThe hawks eat more dark mice than light mice because they can see the dark mice more easily
- 24. Multiple ChoiceDarwin determined that the 13 species of finch found in the Galapagos Islandsprobably all came from the same ancestral specieshad all adapted to the same food sourcewere identical to species 600 miles awaywere the result of careful breeding by humans
- 25. Multiple Choice
