Mutations are spontaneous and occur at random however there are some mutagenic agents which increase the chance of this happening such as radiation exposure. If it is a point shift mutation then only a few bases on the dna sequence are changed so only changes a few of the amino acids in that chain (such as inversion of a base). If its a frame shift then the base sequence is altered so much so that every amino acid from after that changes (such as deletion of a base) which can create things such as cri-du-chat syndrome which results from a piece of chromosome 5 is missing. Hope this helps:)

our elements that comprise over 95% of the human body are _____. carbon, phosphorus, oxygen, hydrogen calcium, phosphorus, hydro
Aleonysh [2.5K]
I believe the correct answer would be the third option. Our elements that comprise over 95% of the human body are <span>carbon, hydrogen, oxygen, nitrogen. Carbon and hydrogen is the backbone of any hydrocarbon or organic compound. The cells in our body are made up organic compounds thus our body is mostly composed of carbon and hydrogen. Oxygen is also present in high percent in our body since it is important for the processes of the cells. Also, nitrogen should be present in our body in large amount since it is present in proteins which is found in our body's cells and tissues.</span>
