In which way are photosynthesis and cellular respiration similar?
Both processes destroy energy.
Both create energy.
Photosynthesis breaks down sugar while cellular respiration produces sugar.
Both processes transfer energy from one form to another.
What is the correct equation for cellular respiration?
oxygen + sugar -> carbon dioxide + water + Energy
carbon dioxide + sugar + Energy -> carbon dioxide + water
carbon dioxide + water -> oxygen + sugar + Energy
carbon dioxide + water + Energy -> oxygen + sugar
What is important about cellular respiration?
It produces energy from the sun.
It forms sugar.
It transforms sugar into a usable form of energy (ATP)
Only plants perform this process.
Which organ excretes (gets rid of) carbon dioxide?
Lungs
Liver
Heart
Kidney
One molecule needed for cellular respiration is
carbon dioxide
glucose
water
chlorophyll

You are alone on an island in the middle of the Atlantic Ocean. You are hot and thirsty, so you want to drink water from the ocean. You think about biology class and you decide:
to drink the ocean water because the extra salt will quench your thirst.
not to drink the ocean water because the extra salt will cause you to dehydrate.
to drink the ocean water because your cells will burn more fat due to the salt intake.
not to drink the ocean water because the extra salt will cause your cells to burst.
Transport of water molecules across a cell membrane allows cells to maintain stable internal conditions in an ever-changing environment. This stable internal condition is called _____.
homeostasis
energy transfer
osmosis
carrying capacity

Water from the solution will move into the red blood cell.
Water from the red blood cell will move into the solution.
Protein and sugar will move from the solution into the red blood cell.
Protein and sugar will move from the red blood cell into the solution.
