Respiration and Physical and Chemical Changes

The process of breaking down of food in the cell with release of energy is called

• Digestion

• Cellular respiration

• Circulation

• Excretion

Anaerobic respiration.....

• doesn't require CO₂

• requires CO₂

• doesn't require oxygen
• requires oxygen

When breakdown of glucose occurs with the use of oxygen it is called

• aerobic respiration

• anaerobic respiration

• cellular respiration

• anaerobes

Earthworms skin is

• moist and slimy

• moist and rough

• rough and slippery

• rough and slimy

What are the products of anaerobic respiration in a human cell?

• Energy and Lactic Acid

• Lactic Acid

• Lactic Acid and Carbon Dioxide

• Carbon Dioxide and Water

During inhalation diaphragm moves

• Down

• Left

• Right

• Up

Small openings on the side of the cockroaches body is called as

• Trachea

• Spiracles

• Glucose

• None

These organs help our body to breath except

• Nasal cavity

• Lungs

• Trachea

• Mouth

Lungs are present in the

• Chest Cavity

• Nasal cavity

• Respiration

• Diaphragm

In the cells oxygen is used to break down

• glucose into carbon di oxide

• Glucose into carbon di oxide and water

• water into carbon di oxide

• carbon di oxide into water
