Help me because I mean you should cuz it's a nice thing to do ​

the answer is C

Explanation:

Mutations are genetic changes in the DNA sequence of the genome in a particular organism. Mutations are caused by adding one or more extra nucleotides into the DNA (i.e. insertions), deleting nucleotides (i.e. deletions), or replacing nucleotides (i.e., substitutions). Due to the diverse nature of mutations, it is expected that they have different effects on the gene product (i.e., the resulting protein). For example, a deletion or an insertion, which are collectively are referred to as 'indels' mutations, may generate frameshift mutations that shift the way the DNA sequence is read. Moreover, if a nucleotide letter is written backward, it doesn't change the final product (i.e., the nucleotide sequence), which is represented in the example with the C option.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
