Many human actions are reflexes. Which statement describes a reflex action?

Answer options:

A reflex action does not need a sense organ.

A reflex action is a slow action.

A reflex action is automatic.

How to approach this question

Consider the characteristics of a reflex, such as blinking or pulling your hand away from a hot object. Are they slow or fast? Do you think about them before they happen? Do they involve detecting a stimulus? Evaluate each statement based on these characteristics.

Full Answer

C.A reflex action is automatic.✓ Correct

A reflex action is automatic.

A reflex action is a rapid, involuntary (automatic) response to a stimulus. The purpose of most reflexes is to protect the body from danger. - They are not slow; they are extremely fast. - They require a sense organ (or receptor) to detect the stimulus. - They are automatic, meaning they occur without conscious control or thought.

Common mistakes

✗ Thinking reflexes are slow. They must be fast to be protective. ✗ Believing a sense organ isn't needed. A stimulus must be detected for a reflex to occur.
