What physical adaptation helps some organisms breathe underwater?

Back

Gills are the physical adaptations that allow some organisms to extract oxygen from water.

Front

What causes variation in heritable traits within a population?

Back

Variation is caused by randomly occurring mutations.

In a population of birds, which moths are likely to survive if the environment changes to favor their color?

Back

Brown moths would survive if the environment changes to favor their color due to camouflage.

Front

Define natural selection.

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in allele frequencies in a population.

Front

Explain the concept of adaptation.

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

What is the significance of allele frequency in evolution?

Back

Allele frequency indicates how common an allele is in a population, influencing the population's genetic diversity and evolution.
