Question 1
1 / -0

The average breathing rate of human beings is:

A
15-18 times

B
15- 25 times

C
10-20 times

D
None of the above

Solution

The breathing rate is defined as the number of times a person breathes in one minute. The normal breathing in an adult person is 15 to 18 times per minute.
So, the correct answer is option A.
Question 2
1 / -0

Insects have respiratory tubules also known as _______.

A
Arteries

B
Spiracles

C
Trachea

D
Veins
Question 3
1 / -0

During aerobic respiration, energy is released in stepwise manner and ATP formation takes place with the help of this energy. What will happen if this energy is released at a single step instead of in parts?

A
Incomplete oxidation of glucose takes place

B
all the amount of energy can be utilized by the cell as more ATP molecules are produced

C
maximum amount of this released energy is wasted in form of heat and cell may die

D
cell will follow anaerobic pathway of respiration
Question 4
1 / -0

Breathing rate ........... during physical exercise.

A
Increases

B
Decreases

C
Remains same

D
Decreases then increases

Solution

Breathing rate is defined as the no. of times a person breathes in one minute. It increases during physical exercise to fulfill the increased demand for oxygen in the body caused by the increase in the metabolic rate.
So, the correct answer is option A.
Question 5
1 / -0

Accumulation of which of the following molecules in the muscles occurs as a result of vigorous exercise?

A
Glycogen

B
Pyruvic acid

C
Glucose

D
Lactic acid

Solution
Question 6
1 / -0

Which of the following is considered to be a breath

A
2 inhalation + 2 exhalation

B
1 inhalation + 2 exhalation

C
2 inhalation + 1 exhalation

D
1 inhalation + 1 exhalation

Solution

The number of times a person breath is called breathing rate. A breath consists of one exhalation and one inhalation. Inhalation involves breathing in the air while exhalation involves the breathing out the air.
So the correct answer is '1 inhalation + 1 exhalation'.
Question 7
1 / -0

Which of the following activities is characterised by minimum breathing rate?

A
Sleeping

B
Washing of clothes

C
Cleaning of floor

D
Dancing

Solution

During sleeping, the body has the least activities to carry out, hence it does not require a high amount of oxygen. So it has minimum metabolism and hence minimum breathing rate.
So the correct answer is 'Sleeping'.
Question 8
1 / -0

Lime water turns milky when the exhaled air is expelled in the test tube because of the presence of

A
Carbon dioxide

B
Oxygen

C
Nitrogen

D
None of the above
Solution
- When carbon dioxide is passed through lime water for a short time,it turns lime water milky due to formation of a white precipitate of calcium carbonate.
- Exhaled air contains less oxygen and more carbon dioxide.
- The carbon dioxide present in exhaled air turns lime water milky.
- So the correct answer is 'Carbon dioxide'.
Question 9
1 / -0

Spiracle is the respiratory organ of:

A
Cockroach

B
Birds

C
Earthworm

D
Plants

Solution

A spiracle is a respiratory organ in insects such as cockroaches. It is an external opening present on the sides of the abdomen of the body. They are connected with tracheal tubes for gas exchange. Oxygen-rich air rushes through spiracles into the tracheal tubes, diffuses into the body tissue, and reaches every cell of the body. Similarly, carbon dioxide from the cells goes into the tracheal tubes and moves out through spiracles.
So, the correct answer is option A.
Question 10
1 / -0

Select the correct statements.
(i) Between temperature range $$0-25^o$$C, rate of the respiration doubles for every $$10^o$$C rise in temperature.
(ii) Cytochromes are iron-porphyin compounds.
(ii) Respiratory rate of wounded or injures plant parts generally decreases.

A
(i) and (ii)

B
(ii) and (iii)

C
(i) and (iii)

D
(i),(ii) and (iii)

Solution

Wounding or injuring an organ of a plant increases the rate of respiration. It is probably due to the formation of growth hormone, traumatic acid, which increases the meristematic activity, resulting in callus formation.
