The building blocks of life
What are cells?
Carries blood towards the heart
What are the veins?
state of matter where the particles vibrate in fixed positions
Solid
Energy an object has due to its postion, properties, or forces acting on it.
What is potential energy?
The energy that is the result of the movement of particles
What is thermal energy?
Protects the cell membrane in only plant cells
What does the cell wall do?
Muscles allowing the rib cage to expand
What are intercostal muscles?
The state of matter where particles are free to move around each other but are still bound by weak attractive forces
What is liquid?
The energy of movement
Kinetic Energy
The transfer of thermal energy
What is heat?
Where glucose is turned into atp
What is mitochondria?
A tiny air sac that allows oxygen to be exchanged for carbon dioxide
What is an alveolus?
Causes objects to increase in volume when heated due to particles moving further away
What is thermal expansion
Looks like a long line followed by a short line in circuit diagrams
What is a battery?
Conduction
Sends out orders to the rest of the cell's organelles on what to do.
What does the Nucleus do?
Filters waste produced by the body

The formula for density is density = speed over time
What is the formula for density?
The formula for energy efficiency
What is useful output energy/total in put energy * 100?
The transferring of heat energy due to the moment of heated fluids
Convection
Causes the green colour in the site of photosynthesis in plant cells
What is chlorophyll?
Is responsible for oxygen carrying in red blood cells
What is hemoglobin?
Emission of electrons from atoms due to the absorption of energy from electromagnetic waves
what is the photo-electric effect
The movement of positive and negative charged particles
Electrical Energy
The transfer of energy through electromagnetic waves.
Infrared Radiation
