Why?
100

Every living cell respires.

TRUE.

100

These are the many spaces inside the lungs which are filled with air when we breathe.

Air sacs or Alveoli

100
Force that causes a change in motion.
What is an unbalanced force?
100
The star closest to our planet.
What is the Sun?

Glucose + Oxygen = Carbon dioxide + Water. This is called Aerobic Respiration. Why is it described as "aerobic"?

Because the Oxygen that combines with the glucose in this reaction comes from the AIR.

200

Respiration means the diffusion of gases between the air sacs and the blood.

FALSE. That is "breathing".
200

These are the blood vessels where blood from the heart passes through and goes to the air sacs inside the lungs.

Capillaries

200
A push or a pull that changes the motion of an object.
What is a force?
200
The path one object takes around another object in space.
What is an orbit?
200

What is Aerobic Respiration? 

Aerobic Respiration is the release of energy from Glucose by reacting it with Oxygen inside living cells.

300

Expired air (breathed out) contains less carbon dioxide than inspired air (breathed in).

FALSE. Expired air contains more carbon dioxide than inspired air.

300

This is the red pigment inside the red blood cells that helps to carry oxygen.

Hemoglobin

300

A force that causes a spring scale to show weight of an object.

What is gravity?

300
One of these takes about 365 days.
What is Earth's revolution around the Sun?
300
Materials that do not let light pass through them.
What is opaque?
400

"Carbon dioxide + Oxygen" are the products of AEROBIC RESPIRATION.

FALSE. Carbon dioxide + Water

400
A green food-producing molecule that helps plants make their own food.
What is chlorophyll?
400
The measure of distance an object moves in a given time.
What is speed?
400
This takes about 27 days.
What is the moon's revolution around the Earth?
400
For a sound to happen, a medium is needed to do this.
What is vibrate?
500

"Glucose + Carbon Dioxide" are the precursors of AEROBIC RESPIRATION.

FALSE. Glucose + Oxygen
500

These cells carry more carbon dioxide when they came from the heart. Then they travel to the air sacs where they get more oxygen to distribute to all the cells in the body.

Red blood cells

500
A force that opposes motion and acts between 2 objects that are touching.
What is friction?
500
the Earth does this in a 24 hour period.
What is rotate on it's axis?
500

What is the difference between BREATHING and RESPIRATION?

Breathing = movement of air/gases into and out of the lungs

Respiration = breakdown of food to release energy, which takes place in all body cells
