Assertion : Earthworms come out of their burrows on rainy days. Reason : Rain water fills up their burrows which deprive them of \(\mathrm{O}_{2}\)
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Earthworms, as the common name implies, live underground, and like most terrestrial creatures, breath air. Oxygen uptake, however takes place through the body wall, as earthworms lack lungs. When it rains, the water flows into their burrows (their wormy homes), blocking off their air supply. As you can imagine, this causes the worms a considerable amount of stress. So, the earthworms that you see during or after a big rain are those that either fled to the surface for a breath of air or those that drowned and were washed from their burrows (poor worms).

Assertion : All the terrestrial vertebrates are air breathers. Reason : They have developed lungs for breathing an adaptation for land life.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Terrestrial vertebrates have developed lungs as their respiratory organs. They breathe in air through nostrils which later enters the lungs. There is utilisation of oxygen from air to exchange with carbon dioxide from tissues. This gaseous exchange happens in the lungs. Aquatic animals have special structures called as gills for respiration. These aquatic organisms take in water through their mouth. Dissolved oxygen in water is utilised near the gills to be exchanged with carbon dioxide from tissues.

Skin is an accessory organ of respiration in
1 Human
2 Frog
3 Crocodile
4 Lizard
Explanation:
Amphibians like frogs can respire through their moist skin (cutaneous respiration). Here skin of frog acts as accessory organ for respiration.
