Natural Selection, Adaptations, and Selective Breeding

Variation: The differences in DNA among individuals, which can lead to different traits.

Hollow Bones: Lightweight bones that reduce body weight, aiding in flight.

Adaptation: A trait that improves an organism's ability to survive and reproduce in its environment.

False: During hibernation, an animal's heart rate and temperature decrease to conserve energy.

False: Natural selection typically occurs over long periods of time, leading to gradual changes in species.

Natural Selection: The process where organisms better adapted to their environment tend to survive and produce more offspring.

Camouflage: A trait that allows an organism to blend in with its environment to avoid predators.

Selective Breeding: The process of breeding plants and animals for specific traits.

Variation provides the raw material for natural selection, allowing some individuals to survive and reproduce better than others.
