Answer: anthropochory (human dispersal)
Explanation:
Assuming that the bird pollinators were significantly diminished, human dispersal will be a useful means of dispersal. Currently, in the tropics, Jatropha is intentionally planted by individuals for oil production. 
 
        
             
        
        
        
The correct answer is B
The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .
There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine. 
This  rule is the same with RNA except that here Thymine is replaced with Uracil.  Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
  
 
        
             
        
        
        
Mutualism is when two organisms are involved and they both benefit where as parasites is when two organisms are involved, but one is benefitted while the other is harmed.
