Q51
Which structure in Pheretima is correctly matched with its function?
A Gizzard - absorbs digested food
B Setae - defence against predators
C Typhlosole - storage of extra nutrients
D Clitellum - secretes cocoon
Correct Answer
Option D
Solution

Clitellum secretes cocoon during breeding season.

Gizzard grinds food.

Setae help in locomotion.

Typhlosole increases absorption area in intestine.

Q52
Which of the following is correctly stated as it happens in the common cockroach?
A Oxygen is transported by haemoglobin in blood
B The food is ground by mandibles and gizzard
C Nitrogenous excretory product is urea
D Malpighian tubules are excretory organs projecting out from the colon
Correct Answer
Option B
Solution

Mandibles cut and masticate food while gizzard grinds it.

Cockroach is uricotelic (not ureotelic).

Cockroach has no haemoglobin.

Q53
The ciliated columnar epithelial cells in humans are known to occur in
A Eustachian tube and stomach lining
B Bile duct and oesophagus
C Fallopian tubes and urethra
D Bronchioles and Fallopian tubes
Correct Answer
Option D
Solution

Ciliated columnar epithelium is present in nasal passages, oviducts (Fallopian tubes), terminal bronchioles, brain ventricles and central canal of spinal cord.

Q54
One very special feature in the earthworm Pheretima is that
A The S-shaped setae embedded in the integument are the defensive weapons used against enemies
B It has a long dorsal tubular heart
C The typhlosole greatly increases the effective absorption area of the digested food in the intestine
D Fertilisation of eggs occurs inside the body
Correct Answer
Option C
Solution

The typhlosole is a fold of tissue running the length of the earthworm intestine dorsally, increasing the surface area for absorption.

Q55
The cells lining the blood vessels belong to the category of
A Columnar epithelium
B Connective tissue
C Smooth muscle tissue
D Squamous epithelium
Correct Answer
Option D
Solution

Simple squamous epithelium (endothelium) lines blood vessels, lymph vessels and heart.

Q56
The kind of tissue that forms the supportive structure in our pinna (external ears) is also found in
A vertebrae
B tip of the nose
C ear ossicles
D nails
Correct Answer
Option B
Solution

Yellow elastic fibrocartilage found in pinna, Eustachian tubes, epiglottis and tip of the nose.

Q57
The epithelial tissue present on the inner surface of bronchioles and fallopian tubes is
A Cuboidal
B Glandular
C Ciliated
D Squamous
Correct Answer
Option C
Solution

Ciliated epithelium is found on the inner surface of bronchioles and fallopian tubes.

Q58
Which correctly describes the location of body parts in earthworm Pheretima?
A Two pairs of testes in 10th and 11th segments
B One pair of ovaries attached at intersegmental septum of 14th and 15th segments
C Two pairs of accessory glands in 16-18 segments
D Four pairs of spermathecae in 4-7 segments
Correct Answer
Option A
Solution

In Pheretima, two pairs of testis sacs are in the 10th and 11th segments.

Q59
Which is correct pairing of a body part and the kind of muscle tissue that moves it?
A Biceps of upper arm - smooth muscle fibres
B Iris - Involuntary smooth muscle
C Abdominal wall - smooth muscle
D Heart wall - Involuntary unstriated muscle
Correct Answer
Option B
Solution

The iris of the eye contains involuntary smooth muscle that controls pupil size.

Q60
The cell junctions called tight, adhering and gap junctions are found in
A Connective tissue
B Neural tissue
C Epithelial tissue
D Muscular tissue
Correct Answer
Option C
Solution

Epithelial tissues have cells held together by intercellular junctions including tight, adhering and gap junctions.
