Question

coevolution: 21. what is coevolution? 22. explain what happens with the rough - skinned newt and the common garter snake. artificial selection or selection: 23. what is an example of something we use artificial selection or selective breeding? finding order in biodiversity: 24. what is taxonomy? 25. true or false: each scientific name can refer to multiple species.

Explanation:

1. Coevolution is the reciprocal evolutionary change in interacting species over time. For example, predator - prey or plant - pollinator relationships can drive coevolution.
2. The rough - skinned newt produces a potent toxin as a defense mechanism. The common garter snake has evolved resistance to this toxin. This is an example of an evolutionary arms race, a form of coevolution where the newt's toxin becomes more potent over time and the snake's resistance increases accordingly.
3. Dog breeding is a classic example of artificial selection. Humans have selectively bred dogs for specific traits such as size, coat type, and behavior over many generations.
4. Taxonomy is the science of classifying organisms. It involves naming, describing, and classifying species based on their characteristics and evolutionary relationships.
5. Each scientific name (binomial nomenclature) refers to a single species. So the statement is False.

Answer:

1. Coevolution is the reciprocal evolutionary change in interacting species over time.
2. The rough - skinned newt produces a toxin and the common garter snake has evolved resistance to it, in an evolutionary arms - race coevolution.
3. Dog breeding.
4. Taxonomy is the science of classifying organisms.
5. False
