Natural Selection quiz

What is natural selection?

• The process by which organisms better adapted to their environment tend to survive and produce more offspring.

• The process by which organisms intentionally adapt to their environment

• The process by which organisms are unaffected by their environment

• The process by which organisms randomly change their environment

Explain the process of adaptation in organisms.

• Genetic variation and natural selection lead to organisms becoming better suited to their environment over time.

• Adaptation is a result of organisms intentionally changing their genetic makeup

• Adaptation occurs through random mutations and genetic drift

• Organisms adapt by choosing to change their environment

How does genetic variation contribute to evolution?

• Genetic variation is not influenced by the environment

• Genetic variation allows for the possibility of new traits and characteristics to arise within a population, which can then be selected for or against based on their fitness in a given environment.

• Genetic variation has no impact on evolution

• Genetic variation only leads to negative traits

Give an example of natural selection in action.

• Fish evolving to live on land

• Birds developing the ability to swim underwater

• Peppered moths in England becoming darker in color to blend in with polluted trees during the Industrial Revolution.

• Giraffes growing longer necks to reach higher leaves

How do organisms adapt to their environment?

• Through random mutations and chance

• By staying the same and not changing

• By avoiding their environment completely

• Through natural selection, genetic variation, and evolutionary processes.

What role does the environment play in natural selection?

• Natural selection is solely determined by genetic factors

• The environment selects for traits that are harmful for survival and reproduction

• The environment has no impact on natural selection

• The environment selects for traits that are best suited for survival and reproduction.

Explain the concept of survival of the fittest in the context of natural selection.

• Organisms best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations.

• Survival of the fittest means only the physically strongest organisms survive

• Natural selection ensures that all organisms have an equal chance of survival

• Organisms that are weak and sickly are more likely to survive and reproduce

How does natural selection lead to the evolution of species?

• By randomly selecting traits in each generation

• By causing all organisms to have the same traits

• By favoring traits that increase an organism's chances of survival and reproduction.

• By preventing any changes in the traits of a species

The differences among a species, like different bird beaks, are called

• genes.
• variations.
• traits.
• theories.
