The one advantage of using DNS assay to detect maltose production is the formation of a soluble and colored product compound. 
The reaction that occurs between maltose and DNS in the assay is a redox reaction (reduction and oxidation) such that maltose gets oxidized and becomes Maltonic Acid while the DNS gets reduced into reduced DNS. The  intensity of orange/brown /red color of reduced DNS is proportionately related to the amount of Maltose in the solution.

The right answer is Lichen.
In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.
Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .
 
        
                    
             
        
        
        
Answer:
C
Explanation:
The definition of microtuble is: "a microscopic tubular structure present in numbers in the cytoplasm of cells, sometimes aggregating to form more complex structures." (google) Therefor, it would not be a part of mitosis prophase II.
