  2. a-q, b-, c-r

  3. a-r, b-q, c-p

  4. a-q, b-r, c-p


Correct Option: A

A respiratory disease is?

  1. Cancer

  2. Arthritis

  3. Polio

  4. Asthma


Correct Option: D

Increased asthmatic attacks in certain seasons are related to

  1. Hot and humid environment

  2. Eating fruits preserved in tin containers

  3. Inhalation of seasonal pollen

  4. Low temperature


Correct Option: C
Explanation:

Asthma attacks can be triggered by exposure to allergens, such as pollen, mold or animal dander. This type of asthma is known as allergic asthma. Seasonal allergic rhinitis occurs when a person comes in contact with an allergen or a substance that he or she is sensitive to like pollens.

In which disease, due to flattening of tracheal vessels, alveoli are deprived of oxygen.

  1. Penumonia

  2. Emphysema

  3. Asthma

  4. Bronchitis


Correct Option: C

Read the following four statements carefully.
(i) Ventral respiratory group of neurons of medulla oblongata can cause both inspiration and expiration. 
(ii) The part of the respiratory system starting with the external nostrils up to the terminal bronchioles constitutes the respiratory or exchange part of the respiratory system. 
(iii)  During swallowing epiglottis can be covered by a thin elastic cartilaginous flap called glottis to prevent the entry of food into the larynx.
(iv)  Binding of oxygen with haemoglobin is primarily related to partial pressure of $O _{2}$. 
Which of the above two statements are correct? 

  1. (ii) and (iii)

  2. (iii) and (iv)

  3. (i)and(ii)

  4. (i) and (iv)


Correct Option: D
Explanation:

The part of the respiratory system starting with the external nostrils up to the terminal bronchioles constitutes the conducting part whereas the alveoli and their ducts form the respiratory or exchange part. During swallowing, glottis can be covered by a thin elastic cartilaginous flap called epiglottis to prevent the entry of food into the larynx.

Which of the following options contains the end products formed during anaerobic respiration in yeast?

  1. $H _2O, CO _2$ and energy

  2. $H _2S, C _6H _{12}O _6$ and energy

  3. $CO _2, C _2H _5OH$ and energy

  4. $H _2O$ and $CO _2$


Correct Option: C
Explanation:

Anaerobic respiration in yeast results in the production of ethyl alcohol, carbon dioxide and energy. $C _6H _{12}O _6 \xrightarrow[Complex]{Zymase} \underset{Ethyl \, alcohol}{2C _2H _5OH} + 2CO _2 + $

Inspiration and expiration contain

  1. Oxygen

  2. Oxygen and carbon dioxide

  3. Carbon dioxide

  4. None of these


Correct Option: B
Explanation:

  • Inhaled air contains more oxygen used to create energy and less carbon dioxide.
  •  Exhaled air contains more carbon dioxide produced as a waste product of energy production and less oxygen as it has been used in respiration. Gas exchange takes place by diffusion in the alveoli within the lungs.
  •  As a result, the composition of inhaled and exhaled air is different.

Therefore, the correct answer is option B.

Useful energy is provided to living beings by the process of 

  1. Digestion

  2. Respiration

  3. Regulation

  4. Reproduction


Correct Option: B
Explanation:

Respiration is the process in which nutrients are converted into useful energy in a cell. It is responsible in transporting oxygen and carbon dioxide between cells and the external environment.

Respiration oxidizes

  1. Glucose

  2. Carbon

  3. Nitrogen

  4. None of the above


Correct Option: A
Explanation:

Respiration is a catabolic process that takes place in living organisms. In this glucose is broken down in presence of oxygen to generate ATP along with the production of water and evolution of carbon dioxide. It is an exergonic process. Thus the correct answer is option A.

Calorie is the unit of

  1. Sound

  2. Temperature

  3. Light

  4. Heat


Correct Option: D
Explanation:

The calorie was first defined to measure energy in the form of heat. These units are often used for the total amount of food energy. Nutritional requirements or intakes are expressed in calories per day.
