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.
Answer:
For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). This is considered a "positive" test result, and in this case indicates the presence of a functional group that can be oxidized (alcohol or aldehyde).
Heaps and heaps and heaps and heaps of them!
This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.
