Biology Vocabulary Quiz: Evolution

What is natural selection?

• The process by which organisms intentionally adapt to their environment

• The process by which organisms randomly change their environment

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

• The process by which organisms are created by their environment

Explain the process of natural selection with an example.

• Natural selection is the process of animals choosing their own traits based on their environment.

• Natural selection is the process of humans selecting which organisms will survive and reproduce.

• Natural selection is the process of random genetic mutations causing changes in a population.

• The process of natural selection can be explained with the example of the peppered moth in England during the industrial revolution. Prior to the industrial revolution, the light-colored moths were well camouflaged against the light-colored trees. However, as the industrial revolution caused pollution and darkened the trees, the dark-colored moths became better camouflaged and had a higher survival rate. As a result, the frequency of dark-colored moths increased in the population.

What are the factors that contribute to natural selection?

• Genetic variation, overproduction of offspring, struggle for existence, and differential survival and reproduction

• Predator-prey relationships, symbiotic interactions, food availability

• Climate change, extinction events, migration patterns

• Natural selection, artificial selection, random selection

Describe the concept of adaptation.

• The process by which an organism becomes worse suited to its environment

• The process by which an organism becomes better suited to its environment in order to survive and reproduce.

• The process by which an organism remains unchanged in its environment

• The process by which an organism becomes better suited to a different environment

How do organisms adapt to their environment?

• Through natural selection, genetic variation, and behavioral changes.

• Through random mutations and natural disasters.

• By staying unchanged and resisting any environmental changes.

• Through intentional genetic modification and artificial selection.

Give an example of an adaptation in plants.

• Leaves

• Roots

• Photosynthesis

• Thorns, spines, and prickles

What is genetic variation?

• The process of creating new genes

• The elimination of genes from a population

• Diversity in gene frequencies within a population

• The movement of genes between different species

How does genetic variation contribute to evolution?

• Genetic variation has no impact on evolution

• Genetic variation provides raw material for natural selection

• Genetic variation causes rapid speciation

• Genetic variation leads to extinction

Explain the role of mutation in genetic variation.

• Mutation has no role in genetic variation

• Mutation only occurs in non-coding regions of DNA

• Mutation always leads to harmful genetic variations

• Mutation introduces new genetic variations by altering the DNA sequence.
