Answers:
1.)
Solution: c) Moist
They have their skin moist so that they could absorb oxygen and they secrete mucous to keep their skin moist.
2.)
Solution: c) Mucus secretion
The organisms of Apoda do not have legs but they have scales on the body. Mucus is secreted in them to reduce water loss. Hence, mucus secretion is the right answer.
3.)
Solution: d) Both (b) & (c)
Frogs and toads are not amonotelic instead they are ureotelic as they excrete urea as their waste product.
4.)
Solution: a) Those who can survive on land as well as in water.
Most of the animals either completely live on land or completely live in water. Amphibians are totally different from them as they have dual-mode of life. In the life cycle, both aquatic and terrestrial mode of life is present.
5.)
Solution: c) 2
The body is divisible into two parts i.e. head and trunk. And the tail may be present in some or may not be.
6.)
Solution: d) Tree frogs
Hyla is included in the frogs. They live in freshwater and moist water. Hyla is a tree frog because it lives in a tree.
7.)
Solution: c) i)-b), ii)-c), iii)-a)
Bufa Rana is a toad that is poisonous. On the other hand, frog includes some group of Rana, and tree frog refers to the Hyla because they live on the trees.
8.)
Solution: c) Two auricles, One ventricle
The 3 chambered heart is present in the organisms of Amphibia. Where it includes one ventricle and two auricles. So, option ‘c)’ is the correct answer.
9.)
Solution: d) Ichthyophis
Ichthyophis are known are limbless amphibian as it does not have limbs and it lives in water.
10.)
Solution: a) Eryops
Labyrinthodontia are Stem Amphibia which are the oldest known tetrapods. Eryops is an example of the same. Other Diplocaulus and Lysorophus are examples of Lepospondyli which are small salamanders.
11.)
Solution: b) Fertilisation is internal
Fertilization is external where male gamete is released into the water and it reaches a female non-motile egg and fuses with it hence option b is incorrect.
12.)
Solution: d) Ear
The tympanum transmits sound waves to the middle and inner ear to the brain to interpret.
13.)
Solution: d) Amphibia
Dicondylic skull means the skull is connected to the body with two articulatory condyles.
14.)
Solution: d) Smell
Jacobson’s organ is the part of the olfactory system in amphibians that detects heavy moisture-borne odour particles.
15.)
