Assertion-Reason Questions
Q17. Assertion: Only one variable should be changed at a time in a fair experiment.
Reason: This helps identify the factor responsible for the observed change.
Q18. Assertion: Animal cells do not have a cell wall.
Reason: Animal cells require a rigid outer layer for support.
Q19. Assertion: Antibiotics should not be taken unnecessarily for common cold.
Reason: Common cold is generally caused by viruses, whereas antibiotics act against bacteria.
Q20. Assertion: Gases can be compressed easily.
Reason: Gas particles have large spaces between them.
For Q17–Q20, choose the correct option:
