1 / -0

Select the correct option that represents examples of the following types of animals.
(i) Cold blooded animal
(ii) Warm blooded animal
(iii) Animal possessing dry and cornified skin
(iv) Hermaphrodite animal

A
(i) Frog, (ii) Pigeon, (iii) Wall lizard, (iv) Earthworm

B
(i) Pigeon, (ii) Frog, (iii) Crocodile, (iv) Hydra

C
(i) Rabbit, (ii) Fish, (iii) Frog, (iv) Earthworm

D
(i) Fish, (ii) Frog, (iii) Wall lizard, (iv) Starfish
Solution
Correct option: A

Explanation:
- Frog is a cold blooded amphibian, i.e. its body temperature varies with the temperature of the environment.
- Pigeon is a warm blooded animal, i.e. its body temperature remains constant irrespective of the temperature of the environment.
- Wall lizard are reptiles and possesses dry and cornified skin.
- Earthworm belongs to Annelida and is a hermaphrodite animal, i.e., both male and female sex organs are present in the single individual.
- The correct answer is option A - '(i) Frog, (ii) Pigeon, (iii) Wall lizard, (iv) Earthworm'.
Question 2
1 / -0

A microbial biocontrol agent that can be used to control butterfly caterpillars is:

A
Trichoderma polysporum

B
Bacillus thuringiensis

C
Streptococcus

D
Mycorrhiza
Solution
- An example of microbial biocontrol agent is bacteria Bacillus thuringiensis (Bt).
- It can be introduced in order to control butterfly caterpillars.
- These are available in sachets as dried spores that are mixed with water and sprayed onto vulnerable plants such as Brassica and fruit trees, where these are eaten by the insect larvae.
- Thus, the correct answer is option B.
Question 3
1 / -0

Which of these animal has three chambered heart,cloaca and respires by gills,lungs and through skin ?

A

B

C

D

Solution

Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. They have a three chambered heart and have the unique ability to respire by gills, lungs and through skin. The food residue passes into the large intestine where excess water is removed and the wastes are passed out through the cloaca. The example includes frog.
Thus, the correct answer is 'Frog.'
Question 4
1 / -0

Which one of the following is a matching pair of a body feature and the animal possessing it?

A
Ventral central nervous system - Leech

B
Pharyngeal gill slits absent in embryo - Chameleon

C
Ventral heart - Scorpion

D
Post-anal tail - Octopus
Solution
Correct Option: A
Explanation:
- Leech is an animal that belongs to the phylum Annelida.
- These are invertebrates.
- They have a ventral central nervous system.
- Chameleons are from class reptilia.
- They possess a pharyngeal gill slit in their embryonic stage of development because it’s a characteristic feature of the phylum Chordata.
- The scorpion belongs to the phylum Arthropoda. They have a ventral heart.
- octopus does not possess any post-anal tail.
Hence, the matching pair of a body feature and the animal possessing it ventral central nervous system-leech.
Question 5
1 / -0

Identify the animal (A) and name the phylum to which its belongs (B).

A
A - Balanoglossus, B -Hemichordata

B
A - Balanoglossus, B - Cephalochordata

C
A - Nereis, B - Urochordata

D
A - Nereis, B - Annelida
Question 6
1 / -0

Which of the following is an example for link species?

A
Lobe fish

B
Dodo bird

C
Sea weed

D
Chimpanzee

Solution

Lobe fishes are finned fishes. Pectoral and pelvic fins have articulations resembling those of tetrapod limbs. These fins evolved into the legs of the first tetrapod land vertebrates, amphibians.
So, the correct answer is 'Lobe fish'
Question 7
1 / -0

Identify the animals and the classes to which they belong.

A
A - Salamandra, Amphibia; B - Chelone, Reptilia; C - Chameleon, Reptilia

B
A - Salamandra, Reptilia; B - Chelone, Amphibia; C - Chameleon, Reptilia

C
A - Salamandra, Amphibia; B - Chelone, Reptilia; C - Chameleon, Amphibia

D
A - Salamandra, Reptilia; B - Chelone, Reptilia; C - Chameleon, Amphibia
Solution
- Salamandra belongs to the class Amphibia. It is capable of living both on land and water. They may be identified as an amphibian in having mucous glands on their skin.
- Reptilia is a class that includes animals having creeping or crawling modes of locomotion. These are cold-blooded animals with scales on their body and include animals like snakes, turtles, crocodiles, chameleons, etc.
So, the correct answer is option A.

The exoskeleton of arthropods is made up from which material?

A
Chitin

B
Cuticle

C
Suberin

D
Mucopolysaccharides
Solution
- Arthropod bodies are supported by external bones or hardened exoskeleton which is made up of chitin.
- It is produced by their skin which hardens to form a protective outer covering.
- The exoskeleton is a non-living substance that provides protection and prevents water loss from their body.
- So, the correct answer is 'Chitin'.
