- Q1Which term describes the process by which individuals with certain traits are more likely to survive and reproduce in a given environment?AdaptionGenetic VariationNatural SelectionBiological Evolution30s
- Q2Which of the following statements best describes biological evolution?Biological evolution refers to the process of genetic variation within a population.Biological evolution is the change in the inherited characteristics of a species over time.Biological evolution is the process by which individuals with certain traits are more likely to survive and reproduce.Biological evolution refers to the ability of organisms to adapt to their environment.30s
- Q3What term refers to the inherited traits that provide a survival advantage to an organism?Natural SelectionBiological EvolutionAdaptionGenetic Variation30s
- Q4What term describes the genetic differences within a population?Genetic VariationNatural SelectionAdaptionBiological Evolution30s
- Q5Which mechanism determines which individuals in a population are more likely to survive and reproduce?AdaptionBiological EvolutionGenetic VariationNatural Selection30s
- Q6Which of the following statements best describes biological evolution?The development of new species over a short period of time.A gradual change in the inherited traits of a population over successive generations.A sudden change in an individual's inherited traits.A deliberate modification of an organism's genetic material.30s
- Q7What is adaptation?The random mixing of genetic material during reproduction.The process of genetic drift in small populations.The passing on of acquired traits from parents to offspring.The process by which organisms change and develop traits suited to their environment.30s
- Q8What is a homologous structure?An adaptation that helps an organism survive.An organ that has lost its function over time.A sudden change in an individual's inherited traits.An anatomical structure that is similar in different species because of a common ancestor.30s
- Q9What is the role of genetic variation in evolution?It ensures that all individuals in a population have identical traits.It guarantees the survival of all species in a changing environment.It provides the raw material for natural selection to act upon.It accelerates the process of speciation.30s
- Q10Which of the following is an example of natural selection?A tree growing taller to reach more sunlight.A population of insects developing resistance to a pesticide over time.A squirrel gathering nuts for the winter.A lioness teaching her cubs how to hunt.A bird building a nest in a tree.30s
- Q11Which of the following is a key concept of natural selection?Random genetic mutations.Inheritance of acquired traits.Complete dominance of one trait over others.Variation within a population.Selective breeding by humans.30s
- Q12Which of the following statements best describes the process of natural selection?Organisms adapt to their environment by changing their genetic code.Environmental changes directly cause genetic changes in organisms.Organisms with traits that enhance their survival and reproduction are more likely to pass those traits on to future generations.Organisms with desirable traits can choose their mates and pass on those traits.All organisms strive to be the fittest in their environment.30s
- Q13Which of the following is an example of natural selection?Plants growing taller to get more sunlight.A fish changing its color to blend in with its surroundings.A group of bears hibernating during the winter to conserve energy.A rabbit with a random mutation is born with small ears.A population of birds with longer beaks survives better because they can reach food sources that are not accessible to birds with shorter beaks.30s
- Q14Which of the following best exemplifies a trait that would be favored by natural selection?A giraffe with a different coat color, making it more camouflaged.A giraffe with shorter legs, making it harder for predators to catch.A giraffe with a louder call, attracting mates from a distance.A giraffe with a longer neck, allowing it to reach higher leaves on trees.30s
- Q15What is an example of an analogous structure?The nose of a dog and the nose of a cat.The wings of a bird and the wings of a butterfly.The fins of a shark and the fins of a dolphin.The tail of a fish and the tail of a lizard.The legs of a spider and the legs of a grasshopper.30s
