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:
<em>A season of extra rain</em>
Explanation:
A prarie can be described as a habitat which is abundant in grasses. Although some type of shrubs and flowering plants can also be found on this land, grass can be seen abundantly in such ecosystems. 
If a season with extra rain occurs in the prarie habitat, then there will be a production of more grass on this land. As a result, the rabbits will have more food to feed on. Hence, a season of extra rain will increase the carrying capacity for the rabbits. 
 
        
             
        
        
        
In the science world today, both the natural regeneration and stem cell therapy can be used to generate new cells and both processes have thier advantages and disadvantages. The following are the advantages of natural regeneration over stem cell transplants:
1. Natural regeneration is cheaper compares to stem cell transplant.
2. The process of natural regeneration is safe and does not involve the fear of unknown, long time effects like that of stem cell transplant.
3. Naturally regenerated cells can not be rejected by the patient's body but a stem cell transplanted cell can be rejected by the patient's body.
        
                    
             
        
        
        
Hypertonic- the water moves out of the cell 
Hypotonic- the water moves into the cell
Isotonic- no water movement
