The relationship between the bacterium Xenorhabdus nematophila and its nematode host, Steinernema carpocapsae, is classified as
Cloud [144]

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 12 pound shot put and a small metal BB are dropped from a tall tower, inside a vacuum chamber,
hichkok12 [17]

Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.

<h3>What affects the speeds at which these objects fall?</h3>
  • The falling speeds in both air and a vacuum will be the same for both objects.
  • This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
  • The same will occur in water if and only if the densities of the two objects are equal.

Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.
