Question

S1: Reflex actions are under the conscious control.
S2: Spinning of web by spiders is an example of reflex action.

• A. S1 is true and S2 is false
• B. S1 is false and S2 is true
• C. Both S1 and S2 are false
• D. Both S1 and S2 are true

Answer 1

The correct option is C Both S1 and S2 are false

$\bullet$ Reflex actions are instinctual behaviours that are not under our consious control. For example, when we accidentally touch a hot pan, we suddenly remove our hand from it even without thinking.
$\bullet$ Spinning of web by spiders is not a reflex action as it is not in response to a stimulus. Reflex is always with response to a stimulus but instinct is not.
$\bullet$ As spiders do not learn how to spin a web, it is an instinctual behaviour.
Hence, both the statements, S1 and S2 are incorrect.
