Adaptations, Natural Selection, and Classification

Front

What is overproduction in the context of natural selection?

Back

Overproduction refers to the phenomenon where organisms produce more offspring than can survive, ensuring that some will reach adulthood and maintain the population.

Front

What is a dichotomous key?

Back

A dichotomous key is a tool used to identify organisms based on a series of choices that lead the user to the correct name of a given item.

Front

Back

An adaptation is an inherited trait that increases an organism's chance of surviving and reproducing in its environment.

Front

What is the kingdom Animalia?

Back

The kingdom Animalia includes all animals, which are multicellular, eukaryotic organisms that are heterotrophic and typically capable of movement.

Front

What are some examples of adaptations?

Back

Examples of adaptations include camouflage in animals, the ability to store water in cacti, and the long neck of a giraffe for reaching high leaves.

Front

What is natural selection?

Back

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

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population, which can lead to different traits.

Front

What is the significance of adaptations in finding food?

Back

Adaptations can help organisms find food more efficiently, such as the long beak of a hummingbird for reaching nectar.

Front

What does it mean for an organism to have a biological advantage?

Back

A biological advantage means that an organism has traits that give it a better chance of surviving and reproducing compared to others.

Front

What is the phylum Chordata?

Back

The phylum Chordata includes animals that have a notochord, a dorsal nerve cord, and pharyngeal slits at some stage of their development.
