Biology Unit 6 Review

Match the following

• Microevolution

• Evolution on a large scale affecting changes in species across populations

• Macroevolution

• Evolution can occur on a small scale affecting a single population

• Natural selection

• Process by which individuals that are better adapted to their environment survive and reproduce more successfully

NGSS.MS-LS4-4

Match the following

• Descent with Modification

• differences in the physical traits of organisms

• Adaptation

• a feature that allows an organism to better survive in its environment.

• Overproduction of Offspring

• • Lots of offspring and limited resources causes competition for those resources.

• Variation

• • A change in gene frequency over time. Beneficial traits should become more common over time.

NGSS.MS-LS2-1

Match the following

• Genetic Drift

• random change in the frequency of alleles in a population over time.

• Mutations

• movement of genes into/out of a population.

• Natural Selection

• organisms more fit for their environments will survive and reproduce more offspring.

• Gene flow

• The selection of traits that aren’t necessarily good for survival fitness, but without them, you can’t pass on your genes at all because you can’t reproduce.

• Non-random mating (sexual selection)

• any change in a DNA sequence.

NGSS.MS-LS4-4

Match the following

• Punctuated equilibrium

• forming of a new species by evolution from a pre-existing species

• Gradualism

• Bursts of changes followed by periods of stability

• Speciation

• elimination of a species

• Extinciton

• Slow, constant changes over a long period of time

NGSS.MS-LS4-2

Match the following

• Coevolution

• A number of different species arise from one common ancestor

• Divergent Evolution

• Occurs when two populations of organisms form a specialized relationship and thus change in response to each other

• Convergent Evolution

• When unrelated species evolve similar characteristics because they live in similar environments

NGSS.MS-LS2-2

Match the following

• Biochemistry

• study of the form of living things

• Embryology

• study of embryo development

• Morphology

• study of chemical processes in living things

• Paleontology

• study of prehistoric life through the fossil record

• Biogeography

• study of the geographic distribution of plants and animals

NGSS.MS-LS1-6

NGSS.MS-LS4-1

NGSS.MS-LS4-3

Match the following

• homologous structures

• Structures with little or no function to an organism; could be leftover from an ancestor that had used the structure

• analogous structures

• similar structures that evolved independently in different organisms due to serving similar purposes; different structurally, but same functionally

• vestigial structures

• Similar structures, but different function; suggest common ancestry
