Answer:
There is no diagram in this question but the question can still be answered without it. 
B. hold the cell membrane together, and proteins move chemicals across the cell membrane
Explanation:
The fluid mosaic model, which describes the structure of the cell membrane, reveals that it contains both lipids and protein constituents. These components, however, performs different functions in the cell membrane of organisms. 
The lipid component of the cell membrane, which comprises of glycolipids and cholesterol, hold the cell membrane together while proteins called transport proteins help move chemicals across the cell membrane. 
 
        
             
        
        
        
Their safety is dangerous when they don't use a common measurement is because they don't know what are safe amounts of this dangerous chemical for them to use. Because they're using dangerous chemicals without a common measurement - this obviously puts them at risk. 
        
             
        
        
        
B. Are the monomers of dna and rna
        
             
        
        
        
Because of their relatively simple genetic structure when compared to other organisms. Not to mention, they breed in extremely high numbers which is great for scientists looking to do many trials, as most are. Their life cycle is also very short which means we can observe their entire life span and witness the effects of testing at all stages.
