Unifying Themes in Life Science

Heredity (Life Science Unifying Concept A)
Heredity is the genetic passing of a set of instructions from generation to generation. These instructions are encoded as DNA and may manifest themselves as characteristics. Some characteristics are inherited, and some result from interactions with the environment.

Click here to download a practice multiple choice review sheet related to Heredity. This 2-page sheet was prepared to assist teacher and student in practicing High School Science Proficiency Exam (HSPE) style questions related to the benchmarks contained within the unifying theme of Heredity. The file contains questions, answer key, and Depth of Knowledge (DOK) coding.


Structure of Life (Life Science Unifying Concept B)
All living things are composed of cells. Cells range from very simple to very complex and have structures which perform functions for the organism. Cells and structures can be damaged or fail because of intrinsic failures or disease.

Organisms and Their Environment (Life Science Unifying Concept C)
A variety of ecosystems and communities exist on Earth. Ecosystems are dynamic interactions of organisms and their environment. Ecosystems have distinct characteristics and components that allow certain organisms to thrive. Change in one or more components can affect the entire ecosystem.

Diversity of Life (Life Science Unifying Concept D)
Evidence suggests that living things change over periods of time. These changes can be attributed to genetic and/or environmental influences. This process of change over time is called biological evolution. The diversity of life on Earth is classified using objective characteristics. Scientific classification uses a hierarchy of groups and subgroups based on similarities that reflect evolutionary relationships.
