AQA GCSE · Question 02.3 · Homeostasis and Response
Which two human actions are reflexes?
How to approach this question
A reflex action is automatic, involuntary, and rapid. It is not a learned skill or a conscious decision. Read through the five options and identify the two actions that fit this description.
Full Answer
["Blinking when an insect flies into the eye", "Removing the hand from a hot object"]
Reflex actions are involuntary and serve a protective function.
- **Blinking when an insect flies into the eye:** This is a cranial reflex to protect the eye. It is automatic.
- **Catching a ball:** This is a voluntary action coordinated by the brain.
- **Playing a musical instrument:** This is a learned, voluntary skill.
- **Removing the hand from a hot object:** This is a spinal reflex to prevent burns. It is automatic.
- **Writing a message:** This is a conscious, voluntary action.
Therefore, the two reflexes are blinking and removing the hand from a hot object.
Common mistakes
✗ Choosing voluntary actions like catching a ball or playing an instrument. These require conscious thought and are not reflexes.
