What types of neurons are responsible for sending movement information to your muscles
Motor neurons
How does light play a role in the circadian rhythm
True or False: low mass stars explode into supernovae at the end of their life
What is the difference between a cell wall and a cell membrane
cell wall only found in plant cells and bacteria - not animal cells. Used for support and stability
Cell membrane found in all cells -- controls what enters and exits the cell

What happens during REM?
Vivid dreams, muscle paralysis, brain waves similar to waking
What happens to form a star?
Early stars are formed from a nebula - a cloud dust and gas sticking together under the pressure of gravity
What is photosynthesis? Where does it occur?
Conversion of the suns energy into usable chemical energy
Occurs in the chloroplasts
What is a base
A substance that produces hydroxide ions (OH-)
What is the function of the parietal lobe?
Responsible for information processing (touch, temperature, pain) and helping with spatial processing
How does sleep change throughout the night?
Sleep cycle has more NREM at the beginning of the night, and more REM at the end.
