Define Wave.
A disturbance that travels through a medium from one location to another.
Define Trait.
A characteristic of an organism.
The highest point of a wave.
Crest
Is white light a color? Why?
No it is the combination of all colors.
What are the three ways waves can interact with an object?
Reflection, Absorption, and Transmission.
Define Source.
The thing or object that a wave is moving away from or that creates the wave.
Define Gene.
The sequence of DNA that codes for a protein.
The lowest point of a wave.
Trough
Is black the absence of color? Why?
Yes, it absorbs every color of light and doesn't reflect any.
If an object/environment is absorbing sound/light it is making it...
Quieter/Dimmer
Define a Medium.
The substance that the energy is transferring through.
Define Adaptation.
An organism changing its traits over a short period of time to better suit its environment.
The distance between the crests of two waves.
Wavelength
What is the position where a wave would settle and appear as though it were no longer moving?
Rest Position
If an object/environment is reflecting sound/light it is making it...
Louder/Brighter
Define Reciever.
The item that a wave is moving towards.
How do bed bug mutations help them survive?
The pesticide no longer works on them because their genes have mutated.
The distance between the the rest position of a wave and its highest or lowest point.
Amplitude
A weak wave would have what set of characteristics?
Low Amplitude, Long Wavelength, Low Frequency
What is the key difference between adaptation and evolution?
Adaptation is short-term change within a generation, evolution is long-term across multiple generations.
What's the difference between a transverse wave and a compression wave?
A transverse wave moves back and forth while a compression wave moves in and out.
Define Natural Selection.
The process by which the strongest traits naturally are passed down through generations to help more organisms in a species to survive.
How many waves happen in a certain amount of time is called the...
Frequency
A powerful wave would have what set of characteristics?
High Amplitude, Short Wavelength, High Frequency
Which changes first when items mutate– a protein function or a protein structure? Why?
Protein structure. The structure determines the function.
