Question

12. Assertion - Smell of burning incense stick spread all around due to the diffusion of
its fume into air
Reason - Increased temperature results in increase kinetic energy of the molecule
13. Assertion - Prokaryotic cells are primitive and larger than eukaryotic cells
Reason:- Prokaryotic cells lack cytoplasmic organelle​

Answer 1

Answer:

12. Assertion and reason are both right but in 13. assertion is right and reason is wrong

Answer 2

Answer:

12. Both assertion and reason are correct and the reason is the correct explanation of the assertion.

• Due to the smoke from burning incense sticks diffusing into the air, the scent of burning incense sticks fills the entire room.
• Additionally, it spreads as a result of the particles' constant motion in all directions. Due to the increase in kinetic energy caused by heating, the smell fills the entire space quickly.
• Large intermolecular gaps in both air and aroma allow them to easily occupy each other's spaces. As a result, when the incense stick is ignited, the particles in the air fly quicker since heating increases their kinetic energy.

13. The assertion is wrong but the reason is correct.

• Prokaryotic cells are smaller than eukaryotic cells in size. The cytoplasmic membrane-bound organelles are likewise absent in these cells. As a result, the cytoplasm's poorly developed components carry out the majority of tasks.
