GED® Science: Homeostasis & Life Science Data (Deep Dive)
A deep dive into how living things stay in balance and how to reason with science data, expanding the single 'Homeostasis & Reading Science Data' lesson from the GED® Life Science course into a full mini-course. You'll learn how feedback loops keep conditions like temperature, water, and blood sugar stable, how organisms respond to their environment, and the core science-reasoning skills the GED® rewards: reading graphs and tables, telling claims from evidence, designing fair experiments, and knowing why correlation is not causation. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice.
