Questions and Answers

Match the following terms related to evolutionary biology with their correct definitions:

Natural Selection = The process by which the distribution of traits in a population changes over many generations. Adaptive Trait = A trait that makes it more likely that an individual will survive in a specific environment. Mutation = A random change to a gene that sometimes results in a new trait. Variation = Any difference in traits between individual organisms.

Match the organism-related terms with their descriptions:

Organisms = Living things, such as plants, animals, and bacteria. Species = A group of organisms of the same kind that do not reproduce with organisms from any other group. Population = A group of individuals born and living at about the same time. Prey = An animal that is hunted or killed by another animal for food.

Match these genetic terms with their meanings:

DNA = A type of molecule that genes and chromosomes are made of. Gene = An instruction for making a protein molecule. Gene Version = A specific form of a gene that provides instructions for making a particular protein molecule. Mutation = A random change to a gene that sometimes results in a new trait.

Match the ecological roles with their descriptions:

Predator = An animal that hunts and kills other animals for food. Prey = An animal that is hunted or killed by another animal for food. Environment = Everything (living and nonliving) that surrounds an organism. Camouflage = A way of hiding by looking the same as the background. Signup and view all the answers

Match the terms related to traits with their descriptions:

Trait = A specific characteristic of an individual organism. Adaptive Trait = A trait that makes it more likely that an individual will survive in a specific environment. Non-Adaptive Trait = A trait that makes it less likely that an individual will survive in a specific environment. Variation = Any difference in traits between individual organisms.

Match the statistical and biological terms with their definitions:

Distribution = The number of individuals with each trait in a population. Histogram = A graph that uses bars to show how characteristics or values are distributed within a group. Population = A group of individuals born and living at about the same time. Species = A group of organisms of the same kind that do not reproduce with organisms from any other group.

Match the stages of life and scientific inquiry terms with their definitions:

Offspring = An organism produced as a result of reproduction. Nymph = A young insect that looks somewhat different from the adult. Hypothesis = An idea about what might happen that is based on what you already know. Survive = To stay alive. Signup and view all the answers

Match the hereditary and evolutionary terms with their appropriate definitions:

Ancestor = A related organism from a previous generation. Gene = An instruction for making a protein molecule.
