Answer:
The correct answer will be-cooperate
Explanation:
Nematodes or ringworms interact with the bacteria in one of three ways: mutualism, parasitism and symbiosis.
The interaction between nematode <em>Steinernema carpocapsae</em> and bacteria <em>Xenorhabdus nematophila</em> prove to be a symbiotic relationship as both the organisms benefit each other.
The interaction between these two organisms is also known as cooperation because both the species can live without each other also. It is during the infective juvenile stage, the bacteria start living in the intestine of the nematode and benefiting the nematode. Both bacteria and nematode help each other killing the host and then utilizing the cadaver of the host.
Thus, cooperate is the correct answer.
A single insertion or deletion of a nucleotide will basically lead to a frameshift mutation where the “reading frame” is disrupted. Normally, amino acids are encoded by three nucleotides, called a codon.
