Given illustrations or descriptions, students will identify disruptions of the cell cycle that lead to diseases such as cancer.

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.

Given examples, students will recognize the importance of taxonomy to the scientific community.

Given illustrations or descriptions, students will determine the classification of organisms into domains and kingdoms.

Given images, videos, or scenarios, identify and describe the responses of organisms, populations, and communities to various changes in their external environment.

Identify and describe internal feedback mechanisms involved in maintaining homeostasis given scenarios, illustrations, or descriptions.

Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.

Given scenarios, illustrations. or descriptions, the student will compare variations and adaptations of organisms in different ecosystems.

Given laboratory investigation scenarios, students will distinguish between scientific hypotheses and scientific theories.

Given field and laboratory scenarios and laboratory data, students will construct data tables and graphs, using repeated trials and means to organize data.

Given laboratory investigation data, students will determine the best conclusion based upon that data.

Given investigation quantitative data, students will determine its degree of precision and/or accuracy and causes for uncertainties in measured data.
