PLEASE HELP For question numbers 14, 15 and 16, two statements are given- one labeled Assertion (A) and the

other labeled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c)

and (d) as given below:

a) Both A and R are true, and R is correct explanation of the assertion.

b) Both A and R are true, but R is not the correct explanation of the assertion.

c) A is true, but R is false.

d) A is false, but R is true.

14. Assertion: The following are examples of isotopes of Carbon and Chlorine: 1 mark

i)^12,6Cand^14,6C ii)^35,17Cland^37,17Cl

Reason: Isotopes are atoms of different elements having different atomic numbers but same

mass numbers.

15. Assertion: Viruses do not show characteristics of life. 1 mark

Reason: Viruses lack any membranes.

16. Assertion: Membrane biogenesis occur in cells 1 mark
