Question 1
1 / -0

The natural voices of men, women and children are different and can be distinguished. A student makes three hypotheses
I. The amplitudes of sounds emitted by them are different.
II. The vocal cords are of different sizes.
III. The vocal cords vibrate with different frequencies.
The correct option is

A
I only.

B
II only.

C
III only.

D
I and III only.
Question 2
1 / -0

In which of the following vertebrate group/groups, heart does not pump oxygenated blood to different parts of the body?

A
Pisces and Amphibians

B
Amphibians and Reptiles

C
Amphibians only

D
Pisces only
Solution
Hint: In single circulatory system that is present in organisms with 2-chambered heart (one auricle and one ventricle).

Part 1 - Definition - Single circulation system
The type of circulatory system in which the blood passes only once through the heart in each complete circuit of the body.
First, the blood will pass through the heart to gills, then after purification, blood will be distributed to different parts of the body. Oxygenated blood will not return to the heart.
In double circulation as in mammals, heart pumps deoxygenated blood to the lungs for purification and oxygenated blood to the different parts of the body.
Part 2 - Two chambered heart
As the name suggests in a two-chambered heart, there are only two chambers: Atria (Auricle) and Ventricle.
Atria (receiving chambers) - are the first stops for blood entering the heart.
Ventricle (pumping chambers) - are the chambers that push blood out of the heart.
Animals with 2-chambered heart use gills for gaseous exchange (respiration).

Part 3 - Examples of organisms
Fishes (Pisces) have the simplest circulatory systems of the vertebrates: blood flows in one direction from the two-chambered heart to the gills and then the rest of the body.
Amphibians and Reptiles have 3-chambered heart while Birds and Mammals have 4-chambered heart.
Part 4 - Conclusion
Fishes have a two-chambered heart which transports deoxygenated blood to gills but doesn't transport oxygenated blood to the different parts of the body.
Final step - Heart that does not pump oxygenated blood to different parts of the body is present in Pisces only.
Question 3
1 / -0

In respiration, air passes through

A
$$Pharynx \rightarrow nasal \:cavity \rightarrow larynx \rightarrow trachea \rightarrow bronchi \rightarrow bronchioles$$

B
$$Nasal \:cavity\rightarrow Pharynx\rightarrow larynx \rightarrow trachea \rightarrow bronchi\rightarrow bronchioles$$

C
$$Larynx \rightarrow nasal \:cavity\rightarrow Pharynx\rightarrow trachea$$

D
$$Larynx \rightarrow pharynx \rightarrow trachea \rightarrow lungs$$

Solution

Nasal cavity open into pharynx which is common passage for transfer of food and air. Pharynx leads to larynx which is also called the voice box. Tracheae carry air to lungs and branch into left and right bronchus for entering left and right lungs. Inside lungs each bronchus divides and subdivides into terminal bronchioles.
Question 4
1 / -0

The only organ which helps frog during respiration while hibernating is

A
Buccopharyngeal cavity

B
Nostrils

C
Lungs

D
Skin

Solution

Frog can respire through gills (as in tadpole), moist skin and lungs. The ability to respire through these different organs reflect aquatic ancestory of frog. During hibernation frog respires through skin and not lungs.
Question 5
1 / -0

Ring of ____ present in trachea, bronchi and bronchioles prevent their collapse when air is not passing through them.

A
Cartilage

B
Bones

C
Collagen

D
Muscle

Solution

Ring of cartilage present in trachea, bronchi and bronchioles prevent their collapse when air is not passing through them. There are fifteen to twenty incomplete C-shaped tracheal rings of cartilage that reinforce the front and sides of the trachea to protect and maintain the airway. There is also lining of hyaline cartilage in the bronchi and bronchioles to give them structural support when air is not passing through them.
Therefore, the correct answer is option A.
Question 6
1 / -0

The form of energy used in the process of respiration is:

A
Chemical energy

B
Electrical energy

C
Mechanical energy

D
Solar energy

Solution

Chemical energy is stored in the bonds of glucose. During the process of respiration (aerobic respiration), the glucose molecule is broken down to release carbon dioxide, water, and energy. This process releases the energy of glucose which is then stored as energy in ATP molecules. ATP molecules are the 'energy currencies of the cell'.
So, the correct answer is option A.
Question 7
1 / -0

Lungs lie in the thoracic cavity separated by .......... from the abdominal cavity.

A
Diaphragm

B
Ribs

C
Stomach

D
None of the above

Solution

Lungs lie in the thoracic cavity separated by a dome-shaped muscular structure known as a diaphragm. It contracts during inspiration to increase the volume of thoracic cavity which decreases the air pressure and leads to inspiration. It relaxes during expiration to decreases the volume of thoracic cavity which increase the air pressure which leads to expiration.
Therefore, the correct answer is option A.
Question 8
1 / -0

Haemocyanin pigment is characteristic of

A
Teleosts

B
Some mollusca

C
Arthropoda

D
Both B and C

Solution

Haemocyanin is blue coloured copper containing respiratory pigment found in some molluscs and arthropods.
Hence the correct option is D.
Question 9
1 / -0

During inspiration, muscles of diaphgram

A
Contracts

B
Expands

C
No effect

D
Coiled like string

Solution

The diaphragm is the membranous structure in the abdomen. The muscles of the diaphragm contracts during inspiration. Muscle contraction allows the diaphragm to become flat which helps to increase the volume of the thoracic cage. This allows the air to be taken in the lungs. During the process of expiration, the diaphragm becomes dome shaped and the muscles relax. This reduces the volume of the thoracic cage and helps to pump the CO$$_2$$ out from the lungs.
Thus, the correct answer is option A.
Question 10
1 / -0

Which of the following is true for respiration?

A
Energy is stored in the form of ADP.

B
Energy is stored and released in the form of ATP.

C
Energy is not released at all.

D
Energy is used up.

Solution

Respiration is a metabolic process through which, living organisms store and release energy in the form of ATP by taking up oxygen and releasing out carbon dioxide.
Hence, option "B" is correct.
