What is the role of oxygen in respiration?

• Oxygen is used to break down glucose to release energy.

• Oxygen is a waste product of respiration.

• Oxygen is used to store energy in glucose.

• Oxygen helps in the absorption of nutrients.

What is the difference between mass and weight?

• Mass is the amount of matter in an object, while weight is the force exerted by gravity on that object.

• Mass is the force exerted by gravity, while weight is the amount of matter in an object.

• Mass and weight are the same and can be used interchangeably.

• Mass is a measure of volume, while weight is a measure of density.

What is the definition of a gas?

• A state of matter that has no fixed shape and expands to fill its container.

• A solid that can change shape under pressure.

• A liquid that has a definite volume but no fixed shape.

• A form of matter that can be compressed into a smaller volume.

What is kinetic energy?

• The energy an object has due to its motion.

• The energy stored in an object at rest.

• The energy released during a chemical reaction.

• The energy associated with an object's position in a gravitational field.
