If thermal energy is removed from a liquid this phase change happens.

This cell organelle converts glucose into ATP (cellular respiration).

This system consists of the kidneys, ureters, bladder, and urethra.

This is the only kingdom that includes no organisms with cell walls.

These particles are found outside of the nucleus of the atom.

For gases, if the volume is kept the same and thermal energy is increased, this also increases.

These small organelles are the site of protein production.

These two systems work together to break down food and carry nutrients throughout the body.

This kingdom is multicellular and heterotrophic but its organisms do not move.

These particles are responsible for bonding in atoms.

If a balloon that is filled with gas is cooled, the balloon will do this.

These two organelles are found only in plant cells.

These two systems work together to maintain homeostasis by regulating body temperature.

This kingdom includes eukaryotic, unicellular organisms, but some are autotrophs and some are heterotrophs.
