What does a nucleus do? - correct answer It contains genetic material and controls the activities of the cell What does cytoplasm do? - correct answer It's a gel-like substance where most of the chemical reactions happen. It contains enzymes that control these chemical reactions What does a cell membrane do? - correct answer It holds the cell together and controls what goes in and out What do mitochondria do? - correct answer These are where most of the reactions for aerobic respiratio...

Reflection - The bouncing back of a wave when it hits a surface through which it cannot pass. Transmission - the passage of light through an object Interference - the combination of two or more waves that results in a single wave Diffraction - The bending of a wave as it moves around an obstacle or passes through a narrow opening Refraction - Change direction and or speed refractive index - a measure of the light-bending ability of a medium Refractive index equation - 300,000kps/speed kps...

Transverse waves The vibrations are at right angles to the direction of travel. Longitudinal waves The vibrations are along the same direction as the direction of travel. Examples of transverse waves Light and other types of electromagnetic radiation, as well as water waves and S waves (a type of seismic wave). Examples of longitudinal waves Sound waves and waves in a stretched spring, and P waves. Equation linking time, period and frequency Period = 1/frequency Equ...
