Survival of the fittest is talking about when you have traits that will help you, you are more likely to live rather than not having those traits. For example, a bird that swims a lot has webbed feet so it has a better chance of surviving then a bird who does not have webbed feet
        
             
        
        
        
During protein synthesis the cell uses information from messenger RNA
        
             
        
        
        
It wouldn't be A because the animals wouldn't really be bothered by each other in the first place. They're not in the same ecosystems..
It wouldn't be D because these animals would be ranked the same if they were in the same phylum.
It could be C, but it's not because there is a variety of other resources for them to use. 
I think B would be the best answer because they are fighting each other for the same resource. You need that resource in order to survive and so does that other organism, so of course both organisms would be fighting over it in order to live
hope this helps!
        
                    
             
        
        
        
Answer:
The experimental results cannot be reproduced.
Explanation:
The ability to follow a specific set of procedures and achieve the same results is one of the key parts of the scientific method.  If the results cannot be replicated, the study is invalid.  Unfortunately, results of invalid studies are sometimes announced to the public before replication attempts can be made to invalidate the study.  Trying to reverse public belief at that point can be impossible.
