A group of tissues creates

• a cell

• another tissue

• an organ

• an organelle

Osmosis is

• the active transport of materials through the cell membrane

• the passive transport of liquids through the cell membrane

• the organelle that signals the guard cell to open

• found only in plants

Thirst is an example of

• an external stimuli

Pitch is determined by

• the brightness of light

• the height of a crest

• the depth of a trough

• the frequency of vibration

The shorter the wavelength

• the lower the pitch.

• the louder the volume.

• the lower the frequency

• the higher the frequency.

Light waves that appear on shiny surfaces will

• reflect

• absorb

• refract
