Both (A) and (R) are true and (R) is correct explanation of the assertion Both (A) and (R) are true and (R) is not correct explanation of the assertion (A) is true but (R) is false Both (A) and (R) are false 5 / 10 Read the assertion and reason carefully to mark the correct option out of the options given below: Assertion: Cell is fundamental structural and functional unit of life. Reason: Anything less than a complete structure of a cell does not ensure independent life. Both (A) and (R) are true and (R) is correct explanation of the assertion Both (A) and (R) are true and (R) is not correct explanation of the assertion (A) is true but (R) is false Both (A) and (R) are false 6 / 10 Read the assertion and reason carefully to mark the correct option out of the options given below: Assertion: Lysosomes have acidic pH. Reason: It is maintain by pumping proton into interior of lysosome. Both (A) and (R) are true and (R) is correct explanation of the assertion Both (A) and (R) are true and (R) is not correct explanation of the assertion (A) is true but (R) is false Both (A) and (R) are false 7 / 10 Read the assertion and reason carefully to mark the correct option out of the options given below: Assertion: Membrane transport occurs through the carrier proteins. Reason: The transport carried by carrier proteins is always passive.
