Answers:
1.)
Solution: b) Agnatha
Cartilage fish belong to class Chondrichthyes, Bony fish belong to Osteichthyes, Amphibians belong to class Amphibia, and Jawless fish belong to Agnatha.
2.)
Solution: c) Hairs on the skin and mammary gland
Hairs on the skin and mammary glands to nourish the young ones are the distinctive feature of mammals.
3.)
Solution: d) All of them
Notochord, pharyngeal pouches, hollow dorsal nerve cord, and postanal tail are the characteristics of phylum Chordata. Organisms of Chordata will have the above characteristics for sure.
4.)
Solution: c) Kangaroo, Dolphin, Loris
These are viviparous because they directly give birth to the young ones, which means they don’t lay eggs.
5.)
Solution: a) Backbone
Vertebrates have a backbone which is also known as the vertebral column. The notochord forms the backbone of the vertebrates.
6.)
Solution: c) Chordates are radially symmetrical
Chordates are bilaterally symmetrical, which means any plane passing through the body divides it into identical left and right halves.
7.)
Solution: c) Pharyngeal pouches
The pouches are present behind the mouth. Pharyngeal pouches develop into tonsils, jaw, and inner ear in terrestrial chordates.
8.)
Solution: c) i)-c), ii)-a), iii)-d), iv)-b)
Scoliodon is the scientific name of dogfish, pristis is the scientific name of sawfish, trygon is the scientific name of sting ray, and myxine is the scientific name of hagfish.
9.)
Solution: c) A tail which extends beyond the anus
The postanal tail is defined as a tail that extends beyond the anus. The tail is present in every chordate at some point in their development.
10.)
Solution: d) Cloaca
This cloaca opens to the exterior to excrete waste materials like urine out of the body.
11.)
Solution: b) Notochord
All vertebrates bear a vertebral column but it replaces the notochord during the embryonic developmental stage.
12.)
Solution: d) Tree frog
The tree frog is the other name for Hyla because they have stripes like a tiger on their body and these markings are of different colors.
13.)
Solution: d) Both a) and b)
The epidermis is made up of two layers. It is modified for the production of feathers, glands, horns, hairs, feathers, and scales.
14.)
Solution: b) Fore limbs
The limbs modify due to evolution to provide flight to the bird. These forelimbs are hollow in nature.
15.)
Solution: b) Subphylum
In the animal classification, Chordata is a Phylum that includes subphylum Vertebrata. Vertebrata includes all the vertebrates.
16.)
Solution: b) Crocodile
The crocodile has a four-chambered heart which consists of two auricles and two ventricles for the supply of blood into the body.
17.)
Solution: d) Caudata
Caudata is a class of Amphibians that includes salamanders and newts. It is not a class of fish.
18.)
Solution: c) Crop and gizzards
Crop and gizzards are the organs of the digestive tract in birds. The crop is used to store food before moving it to the stomach and the gizzard provides churning movement to digest food.
19.)
Solution: b) 2
Fish contains a chamber of the atrium and a chamber of the ventricle. The blood of all fish flows in a single circuit. So, they have two-chambered hearts.
20.)
Solution: a) Pavo, Neophron, Elephas
These are warm-blooded or homeotherms, which mean they have the ability to maintain a constant body temperature irrespective of the environment.
21.)
Solution: a) Gills
Frog respires through lungs when metamorphosis takes place to live on the land. During metamorphosis in frogs, gills disappear and form lungs.
22.)
Solution: b) Vertebral column
The notochord disappears in the adult stage from the spine or vertebral column and this happens due to ossification of the notochord.
23.)
Solution: b) Tailless
Both the frog and toad are tailless and insectivorous amphibians. But, the skin of the frog is smooth and skin of the toad is dry.
24.)
Solution: b) Ventral
In chordates due to evolution, the anterior and middle coelom are shrunken as a result the heart now lies in the ventral position.
25.)
Solution: c) A-ii), B-iii) and C-i)
All of column A includes 3 subphyla of Chordata. Vertebrata includes vertebrates, Urochordata includes tunicates which are invertebrates, and lastly, Cephalochordata includes lancets.
26.)
Solution: c) 3
The phylum chordates are divided into Urochordata or tunicate, cephalochordate, and vertebrate.
27.)
Solution: d) Turtles
Alligators and crocodiles are the animals of the class Crocodilia. Tuataras belong to Class Rhynochocephalia and turtles belong to Class Chelonia.
28.)
Solution: b) Lacks jaw
Instead of a jaw they have a circular toothed mouth with the help of which they bore into the side of a fish and suck out the blood from their prey.
29.)
Solution: b) On land
Internal fertilization takes place in reptiles. Reptiles produce amniotic eggs and they reproduce on the land.
30.)
Solution: d) Both (a) & (c)
Option (b) is incorrect because the heart is not dorsal in chordates instead it is ventral in position.
