B. Density has been decreased Or D.
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:
Explanation:
1st question is humans eat other organisms to get nutrients they need to survive.
2nd one is Eukaryota domain
Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.
