The genetic change causes alterations in only one or a few nucleotide bases in known as mutation.
A mutation is a change in a brief section of a genome's nucleotide sequence. Another frequently replaces one nucleotide in point mutations; other changes involve the insertion or deletion of one or more nucleotides.
Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the leading causes of mutations.
DNA repair enzymes are present in all cells and work to reduce the frequency of mutations. These enzymes reduce genetic information loss, double-strand break formation, and DNA crosslinking by repairing DNA damage.

Answer:
The correct option is;
True
Explanation:
The digestive system of Cnidarians is incomplete having only one single opening which is the gastrovascular cavity the representing the anus and the mouthof the Cnidarians
The hollow body of the Cnidarian polyp which allows water through has tentacles at the top bearing cells meant for stinging
A prey caught by the tentacles is drawn in to the mouth and ingested
The Cnidarians are able to attach to surface due to their attachment adapted lower end
The correct option is therefore true.
