Q21

Match: Bronchioles-Ciliated Epithelium, Goblet Cell-Glandular Tissue, Tendons-Dense Regular Connective Tissue, Adipose Tissue-Loose Connective Tissue

A (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

B (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)

C (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

D (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

Correct Answer

Option A

Solution

Bronchioles are lined by ciliated epithelium (iv).

Goblet cells are unicellular glands (iii).

Tendons are dense regular connective tissue (i).

Adipose tissue is loose connective tissue (ii).

Q22

Which statement wrongly represents smooth muscle?

A These muscles are present in the wall of blood vessels

B These muscle have no striations

C They are involuntary muscles

D Communication among the cells is performed by intercalated discs

Correct Answer

Option D

Solution

Intercalated discs are found only in cardiac muscle tissue. Smooth muscles have no striations and are involuntary.

Q23

Which characteristic is incorrect with respect to cockroach?

A 10th abdominal segment in both sexes bears a pair of anal cerci

B A ring of gastric caeca is present at the junction of midgut and hind gut

C Hypopharynx lies within the cavity enclosed by the mouth parts

D In females, 7th-9th sterna together form a genital pouch

Correct Answer

Option B

Solution

Gastric caeca is at the junction of foregut and midgut, not midgut and hindgut.

Malpighian tubules are at the midgut-hindgut junction.

Q24

Identify the cell junctions that stop leakage across a tissue and facilitate communication between cells:

A Adhering junctions and Gap junctions, respectively

B Gap junctions and Adhering junctions, respectively

C Tight junctions and Gap junctions, respectively

D Adhering junctions and Tight junctions, respectively

Correct Answer

Option C

Solution

Tight junctions stop leakage across tissue.

Gap junctions facilitate communication between cells via rapid transfer of ions and molecules.

Q25

Statements about prostomium of earthworm: (1) Serves as covering for mouth. (2) Helps to open cracks in soil. (3) Is a sensory structure. (4) Is the first body segment. Which are correct?

A (2) and (3) are correct

B (1), (2) and (3) are correct

C (1), (2) and (4) are correct

D (1), (2), (3) and (4) are correct

Correct Answer

Option B

Solution

Prostomium covers the mouth, acts as wedge to open soil cracks, and has sensory receptors.

The first body SEGMENT is the peristomium, not prostomium.

Q26

Cuboidal epithelium with brush border of microvilli is found in

A Ducts of salivary gland

B Proximal convoluted tubule of nephron

C Eustachian tube

D Lining of intestine

Correct Answer

Option B

Solution

Cuboidal epithelium with brush border of microvilli is found in proximal convoluted tubule (PCT) of nephron.

Q27

In humans, ciliated epithelial cells that move particles or mucus are mainly present in:

A Eustachian tube and Salivary duct

B Bronchioles and Fallopian tubes

C Bile duct and Bronchioles

D Fallopian tubes and Pancreatic duct

Correct Answer

Option B

Solution

Ciliated epithelium is present in bronchioles and fallopian tubes.

Q28

Select the correct sequence of organs in alimentary canal of cockroach starting from mouth:

A Pharynx, Oesophagus, Gizzard, Ileum, Crop, Colon, Rectum

B Pharynx, Oesophagus, Ileum, Crop, Gizzard, Colon, Rectum

C Pharynx, Oesophagus, Crop, Gizzard, Ileum, Colon, Rectum

D Pharynx, Oesophagus, Gizzard, Crop, Ileum, Colon, Rectum

Correct Answer

Option C

Solution

Mouth → Pharynx → Oesophagus → Crop → Gizzard → Ileum → Colon → Rectum → Anus.

Q29

Which feature is used to identify a male cockroach from a female cockroach?

A Forewings with darker tegmina

B Presence of caudal styles

C Presence of anal cerci

D Presence of a boat-shaped sternum on the 9th abdominal segment

Correct Answer

Option B

Solution

Male cockroach bears a pair of short threadlike anal/caudal styles absent in females.

Q30

Select the correct route for passage of sperms in male frogs:

A Testes, Vasa efferentia, Kidney, Seminal vesicle, Urinogenital duct, Cloaca

B Testes, Vasa efferentia, Bidder's canal, Ureter, Cloaca

C Testes, Vasa efferentia, Kidney, Bidder's canal, Urinogenital duct, Cloaca

D Testes, Bidder's canal, Kidney, Vasa efferentia, Urinogenital duct, Cloaca

Correct Answer

Option C

Solution

Correct route: Testes → Vasa efferentia → Kidney → Bidder's canal → Urinogenital duct → Cloaca.
