Science

• What are the seven processes that indicate something is alive?

  Movement, respiration, sensitivity, growth, reproduction, excretion, nutrition
• What is respiration in living organisms?

  It converts glucose and oxygen into energy
• What do flowers do in response to sunlight?

  They turn to face the light
