Question 1 of 56
1. Question
- Which of the following statement is correct?
- Nearly 1.5 million species of organism which have been described are different from one another
- Every organism exhibits variation in their external appearance, internal structure and behaviour, mode of living etc.
Correct
Explanation
The variety of living organisms surrounding us is incomprehensible. Nearly 1.5 million species of organism which have been described are different from one another. The uniqueness is due to the diversity in the life forms whether it is microbes, plants or animals. Every organism exhibits variation in their external appearance, internal structure and behaviour, mode of living etc. This versatile nature among the living animals forms the basis of diversity.

Question 43 of 56
43. Question
43. Which of the following statement is correct about Phylum Echinodermata?
- They are exclusively free-living marine animals.
- Body wall is covered with spiny hard calcareous ossicles
- Garden Snail is an example of Phylum Echinodermata
Correct
Explanation
Phylum Echinodermata are exclusively free-living marine animals. These are triploblastic and true coelomates with organ-system grade of organization. Adult animals are radially symmetrical but larvae remain bilaterally symmetrical. A unique feature is the presence of fluid filled water vascular system. Locomotion occurs by tube feet. Body wall is covered with spiny hard calcareous ossicles. e.g- Star fish, Sea urchin.

Question 47 of 56
47. Question
- Vertebrata are grouped into_____ classes.
Correct
Explanation
Vertebrata group is characterized by the presence of vertebral column or backbone. Notochord in an embryonic stage gets replaced by the vertebral column, which forms the chief skeletal axis of the body. Vertebrata are grouped into six classes.

Question 51 of 56
51. Question
- Which of the following statement is correct about Amphibia?
- These are the first four legged (tetra-pods) vertebrates with dual adaptation to live in both land and water
- The heart is four chambered with two auricles and two ventricle.
- Frog and Toad are examples
Correct
Explanation
Amphibia are the first four legged (tetra-pods) vertebrates with dual adaptation to live in both land and water. The body is divisible into head and trunk. Their skin is moist and have mucus glands. Respiration is through gills, lungs, skin or buccopharynx. The heart is three chambered with two auricles and one ventricle. Eggs are laid in water. The tadpole larva, transforms into an adult. e.g-Frog, Toad.

54. Which of the following belongs to Reptilia?
- Calotes
- Lizard
- Tortoise
Correct
Explanation
Reptilia are vertebrates are fully adapted to live on land. Their body is covered with horny epidermal scales. Respiration is through lungs.

Question 54 of 56
54. Question
55. Which of the following statement is correct about Aves?
- Birds are homeothermic (warm-blooded)
- Bones are filled with air (pneumatic bones), which reduces the body weight.
- They lay large yolk laden eggs.
Correct
Explanation
Birds are homeothermic (warm-blooded) animals with several adaptations to fly. The spindle or boat shaped body is divisible into head, neck, trunk and tail. The body is covered with feathers. Forelimbs are modified into wings for flight. Hindlimbs are adapted for walking, perching or swimming. The respiration is through lungs, which have air sacs. Bones are filled with air (pneumatic bones), which reduces the body weight. They lay large yolk laden eggs. They are covered by hard calcareous shell. e.g. Parrot, Crow, Eagle, Pigeon, Ostrich.

56. Which of the following statement is correct about Mammalia?
- Heart is Five chambered and they breathe through lungs
- Placenta is the unique characteristic feature of mammals.
- The external ears or pinnae is present.
Correct
Explanation
Mammals are warm-blooded animals. The skin is covered with hairs. It also bears sweat and sebaceous (oil) glands. The body is divisible into head, neck, trunk and tail. Females have mammary glands, which secrete milk for feeding the young ones. The external ears or pinnae is present. Heart is four chambered and they breathe through lungs. Except egg laying mammals (Platypus, and Spiny anteater), all other mammals give birth to their young ones (viviparous). Placenta is the unique characteristic feature of mammals. e.g. Rat, Rabbit, Man.
