Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.31 Homeostasis and Feedback Loops. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Homeostasis and Feedback Loops: Students analyze negative and positive feedback loops and predict system responses that maintain internal stability. Rigor range: standard concept checks through honors/Pre-AP/AP-ready diagram, model, and stimulus-based cell or system analysis.

Below are sample questions representative of the exercises included on this worksheet and related 10.31 Homeostasis and Feedback Loops skill assessments:

Problem 1Difficulty: Mastery

Use the integrated exercise-response table. Which row best identifies a negative feedback response during intense exercise?

ARising temperature leads to sweating, which traps heat inside the body

BFalling blood glucose leads to more insulin, which lowers glucose further

CPlatelet activation leads to more platelet activation during normal exercise

DRising CO2 leads to faster breathing, which removes CO2

Solution & Explanation:A negative feedback response opposes the original change; faster breathing removes excess CO2.

Problem 2Difficulty: Mastery

Why are positive feedback loops less common than negative feedback loops for maintaining long-term internal stability?

APositive feedback always restores variables to a set point

BPositive feedback cannot occur in living organisms

CPositive feedback tends to move a system farther from its starting condition unless an endpoint stops it

DPositive feedback uses sensors but never responses

Solution & Explanation:Long-term homeostasis usually requires stabilizing variables, while positive feedback amplifies change.

Problem 3Difficulty: Mastery

Use the enzyme feedback diagram. If a mutation prevents the final product from binding the early enzyme, what outcome is most likely?

AThe pathway must stop permanently because the enzyme has no substrate

BThe pathway may overproduce the final product because feedback inhibition is weakened

CThe final product will become a temperature receptor

DThe mutation will create stronger negative feedback than normal

Solution & Explanation:If the product can no longer inhibit the early enzyme, the braking mechanism is weakened.
