Which of the following pair is correct?

(Model of respiratory system = Human respiratory system)

Balloons = Thoracic cavity

Rubber sheet = Diaphragm

Bell jar = Lungs

Y-shaped glass tube = Rib cage

The statements below show various situations in everyday life:

I Siva who dives in the deep sea

II Ah Meng is resting after jogging

III Nora who is diagnosed with anemia

IV Rahman who had arrived at the peak of Mount Everest

Which condition causes increase of respiratory rate?

I and II

III and IV

II and III

I and IV

During inhalation,

diaphragm contracts and flattens

air pressure in the thoracic cavity increases

ribcage moves downwards and inwards

volume of thoracic cavity decreases

Match the parts of the respiratory system with its correct function:

Ribcage = Contracts and relaxes during breathing

Diaphragm = Protects the lungs

Alveolus = Gaseous exchange occurs

Intercostal muscles = Protects the ribcage

Which of the following pathway of oxygen into the lungs is correct?

nostril $\rightarrow$ bronchus $\rightarrow$ bronchioles $\rightarrow$ trachea $\rightarrow$ alveolus

nostril $\rightarrow$ bronchiloes $\rightarrow$ bronchus $\rightarrow$ trachea $\rightarrow$ alveolus

nostril $\rightarrow$ trachea $\rightarrow$ bronchioles $\rightarrow$ bronchus $\rightarrow$ alveolus

nostril $\rightarrow$ trachea $\rightarrow$ bronchus $\rightarrow$ bronchioles $\rightarrow$ alveolus

A student carries out an investigation to study the gases involved in respiration. The following are the steps of the investigation:
1. Five cockroaches are placed in a measuring cylinder
2. Wire gauze is fixed in the measuring cylinder to prevent the cockroaches from crawling out of the measuring cylinder
3. The measuring cylinder is inverted into a container filled with water
4. The height of the water in the measuring cylinder is recorded every 30 minutes for 3 hours
If cockroaches were replaced with germinating seeds, predict your observation.

The water level increases

The water level decreases

Predict the change in the volume of carbon dioxide in the measuring cylinder during this investigation.

The volume of carbon dioxide increases

The volume of carbon dioxide decreases

The energy released in respiration is stored by creating which molecule?

Glucose

Lactic Acid

ATP

ADP

Plants do respiration...

24 hours a day

During the day time

Never

When they cannot photosynthesise

10.

Why do mice have a faster rate of respiration than a hippo?

They have a larger SA:V ratio and need to release more heat energy to stay warm.

They need more energy because they move around more

They have a higher body temperature so they need to release more heat energy

They eat continuously and therefore have more glucose available for respiration

11.

What are the products of aerobic respiration?

Carbon Dioxide and Energy

Lactic Acid

Water and Carbon Dioxide

Glycogen and Carbon Dioxide

12.

What is the chemical formula for glucose?

C₆H₁₂O₆

C₁₂H₆O₁₂

C₆O₁₂H₆

6CH₂O

13.

What is the equation for aerobic respiration?

C₆H₁₂O₆+ 6O₂ --> 6CO₂ + 6H₂O

C₆H₁₂O₆+ O₂ --> CO₂ + H₂O

C₆H₁₂O₆+ 6O₂ --> CO₂ + 6H₂O

6C₆H₁₂O₆+ 6O₂ --> 6CO₂ + 6H₂O

14.

The main tube in respiration is

lungs

trachea

alveoli

bronchial tubes

15.

Smaller branches in lungs are called

pharynx

epiglottis

bronchioles

alveoli

16.

The process of forcing air into the body is called

inspiration

expiration

desperation

motivation

17.

Below are the effects of cigarette tar to a smoker except

Kill cells in the air passage

Increase the production of mucus

Leads to lung cancer

Causing addiction

18.

Ahmad is not feeling well. He is experiencing shortness of breath, wheezing and coughing. Ahmad is probably suffering from

emphysema

bronchitis

asthma

lung cancer

19.

What is the function of air sacs in the respiratory system of a grasshopper?

To slow down the rate of gaseous exchange

To speed up the rate of gaseous exchange

To protect the tracheoles

To protect the spiracles

20.

Stomata is made up of stomatal pore bounded by a pair of guard cells. Stomata of plants close

during photosynthesis

when there is light

when plants gain a lot of water

when it gets dark
