Weekly Quiz Competition

Question 1
1 / -0

The terga, sterna and pleura of cockroach body are joined by

A
Arthrodial membrane

B
Cartilage

C
Cementing glue

D
Muscular tissue

Solution

Cockroach belongs to phylum Arthropoda, and thus shows peculiar characteristics like presence of exoskeleton and the segmented body. Each segment is further divided into four plates such as dorsal tergum, ventral sternum, and two lateral pleurons. These terga, sterna, and pleura of cockroach body are joined by Arthrodial membrane. Hence option A is the correct answer.
Question 2
1 / -0

The cells lining the blood vessels belong to the category of:

A
Smooth muscle tissue.

B
Squamous epithelium.

C
Columnar epithelium.

D
Connective tissue.

Solution

Correct option - B
Explanation for correct option -
Cells lining our blood vessels belong to squamous epithelial tissue. These cells look like skinny, flat plates and have elliptical nuclei.
Question 3
1 / -0

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

A
Pharynx $$\rightarrow$$ Oesophagus $$\rightarrow$$ Crop $$\rightarrow$$ Gizzard $$\rightarrow$$ Ileum $$\rightarrow$$ Colon $$\rightarrow$$ Rectum

B
Pharynx $$\rightarrow$$ Oesophagus $$\rightarrow$$ Gizzard $$\rightarrow$$ Crop $$\rightarrow$$ Ileum $$\rightarrow$$ Colon $$\rightarrow$$ Rectum

C
Pharynx $$\rightarrow$$ Oesophagus $$\rightarrow$$ Gizzard $$\rightarrow$$ Ileum $$\rightarrow$$ Crop $$\rightarrow$$ Colon $$\rightarrow$$ Rectum

D
Pharynx $$\rightarrow$$ Oesophagus $$\rightarrow$$ Ileum $$\rightarrow$$ Crop $$\rightarrow$$ Gizzard $$\rightarrow$$ Colon $$\rightarrow$$ Rectum

Solution

The correct sequence of organs in the alimentary canal of cockroach starting from mount is:
Pharynx $$\rightarrow$$ Oesophagus $$\rightarrow$$ Crop $$\rightarrow$$ Gizzard $$\rightarrow$$ Ileum $$\rightarrow$$ Colon $$\rightarrow$$ Rectum.
So, the correct answer is 'Pharynx $$\rightarrow$$ Oesophagus $$\rightarrow$$ Crop $$\rightarrow$$ Gizzard $$\rightarrow$$ Ileum $$\rightarrow$$ Colon $$\rightarrow$$ Rectum
Question 4
1 / -0

Select the correct match.
A Smooth muscle 1 Present in the wall of the intestine
B Areolar tissue 2 Stores fats
C Bone 3 Tip of nose
D Cuboidal epithelium 4 Present in skin

A
A - 1

B
B - 2

C
C - 3

D
D - 4

Solution

Smooth muscle is a non-striated muscle that is mainly involved in involuntary actions. It is present in the walls of the small intestine.
Adipose tissue stores fats, not areolar tissue.
Cartilage is present at the tip of the nose.
Stratified squamous epithelium is present in the skin. Cuboidal epithelium forms the lining of ducts of salivary glands and lining of kidney tubules.
So, the correct answer is option A.
Question 5
1 / -0

Myelin sheath is produced by

A
Osteoclasts and Astrocytes

B
Schwann Cells and Oligodendrocytes

C
Astrocytes and Schwann Cells

D
Oligodendrocytes and Osteoclasts

Solution

Myelin sheath is also known as medullary sheath. It is an insulating layer which covers the axon and helps to maintain a constant membrane potential. It is produced by Schwann cell in the peripheral nervous system and from oligodendroglia cells.
So, the correct answer is option B.
Question 6
1 / -0

Which of the following is a correct match?

A
Frog - External ears

B
Earthworm - Muscular gizzard, typhlosole

C
Human - Fat globule, 10 pairs of cranial nerves

D
Cockroach - Chilopoda

Solution

Frogs do not have external ears. Instead, they have an eardrum of sorts, called a tympanum, which is just behind each eye. Typhlosole are internal folds of the intestine or intestinal inner wall. Typhlosole occurs in bivalve mollusks, lampreys and some annelids and echinoderms. The gizzard, also referred to as the ventriculus, gastric mill, and gigerium, is an organ found in the digestive tract of some animals, including birds, reptiles, earthworms and some fish. This specialized organ constructed of thick, muscular walls is used for grinding up food; often rocks are instrumental in this process. In certain insects and mollusks, the gizzard features chitinous plates or teeth. Humans have 12 pairs of cranial nerves. Cockroach belongs to class insecta of phylum arthropoda.
Question 7
1 / -0

Microvilli of intestinal epithelium are similar in function with

A
Typhlosole in earthworm

B
Hepatic caecum in cockroach

C
Intestinal caecum in earthworm

D
Malpighian tubules in cockroach.

Solution

Microvilli increases absorptive surface area. Typhlosolar region in earthworm is the middle region of the intestine in which the mid-dorsal wall of the intestine is thrown into a longitudinal fold which is known as typhlosole. The typhlosole increases the absorptive surface of the intestine.
Question 8
1 / -0

Given are the figures of three kinds of muscle fibres. Which one would you find in the grasshopper's legs?

A
A only

B
B only

C
A and C

D
B and C

Solution

The muscles which are present in the legs of a grasshopper are the skeletal muscles. The flexor and extensor muscles which are connected to the tibia bone are the forms of skeletal muscles. These are cylindrical muscle fibres with striations. The myosin and actin filaments make up the muscle fibre.
Thus, the correct answer is option B.
Question 9
1 / -0

The epithelium in the bronchioles is

A
Pseudostratified and columnar

B
Squamous and sensory

C
Pseudostratified and sensory

D
Cuboidal and columnar
Question 10
1 / -0

Which system transmits impulses between different parts of the body?

A
Musculoskeletal system

B
Endocrine system

C
Circulatory System

D
Nervous system

E
Reproductive system

Solution

A complex network of nerve cells or neurons forms the nervous system. This system is responsible for transmitting electrical impulses throughout the body.
So, the correct answer is 'Nervous system'.
