What is the Doppler Effect?

• A change in frequency due to the relative motion of a wave source and an observer

• When a wave overlaps with another wave

• When a wave bounces off of another object

• When a wave bends due to traveling through a different medium

• Mutation

• a type of mutation where one to few bases are substituted with different bases

• Silent mutation

What could be the effect of the mutagen on the organism?

• The mutagen may disrupt gene function to the harm of the organism.

• The mutagen may change gene function in a way that benefits the organism.

• The mutagen may change the genetic material of the cell from DNA to

  proteins.

• The mutagen may have little or no observable effect on the organism.

Answer explanation

Mutagens can disrupt gene function, change gene function (potentially beneficially), or have little to no observable effect on the organism.

What are considered "negative" mutations?

• mutations in the DNA sequence that changes the resulting protein/outcome that harms the organism

• mutations in the DNA sequence that changes the resulting protein/ outcome that benefits the organism

• mutations in the DNA sequence that produces the same protein/ outcome

• all mutations are considered bad and harm the organisms

Answer explanation

Negative mutations are changes in the DNA sequence that result in harmful outcomes for the organism, such as altering proteins in a detrimental way.

What type of mutation is shown in this picture?

• Insertion

• Deletion

• Substitution

• No mutation

What type of mutation is shown in this picture?

• No mutation

• Substitution

• Deletion

• Insertion

Answer explanation

The type of mutation shown in the picture is Deletion, where a segment of DNA is lost. This is evident from the missing portion in the image.
