Performance expectationPlan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis
Examples of investigations could include heart rate response to exercise, stomate response to moisture and temperature, and root development in response to water levels.
Assessment does not include the cellular processes involved in the feedback mechanism.
Every item written to HS-LS1-3 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.

Phenomenon stimulus, connected items across the required types, answer key, rubric and figures drawn deterministically from a structured spec — in the format your students will sit.
