In my Biology Honors Class, they taught about gastric juice, or also known as    (p H) which is formed by stomach glands, is very acidic and can seriously mess up enzyme trypsin functions. After all, enzymes are a type of catalyst that help break down food, which means that enzymes are a sort of digestive acid as well. Hope this helps!
        
             
        
        
        
Given:
m = 12 g, the mass of the cylinder
r = 2 cm, the radius of the cylinder
h = 6 cm, the height of the cylinder.
Calculate the volume, V, of the cylinder.
V = πr²h
   =  π*(2 cm)²*(6 cm)
   = 75.398 cm³
By definition,
density = mass/volume.
Therefore,
density = m/V
             = (12 g)/(75.398 cm³) 
             = 0.159 g/cm³ 
             = 0.16 g/cm³ (nearest hundredth)
Answer: 0.16 g/cm³

I've looked us up ever since you posted it the only thing I can come up with is letter A because it talks a lot about Mountain chains that talks a lot about the ocean floor and the Hawaiian stuff so try a
