The foundation for biological evolution or descent through modification is a) changes in gene frequency in a population occur from one generation to the next. b) mutation, migration, genetic drift, and natural selection cause biological evolution. c) all living things are made of one or more cells. d) organisms adapt to changes in their environment.

The earth consists of a variety of different organisms. despite their diversity, however, some similarities on the structural and metabolic levels may be seen. these similarities can be attributed to a. similarities among organisms in their proteins and nucleic acids. b. the ability of organisms to readily adapt to sudden environmental changes. c. similarities in organisms' habitats and niches. d. the ability of all organisms to interbreed and produce new species.
