Magma in quiet eruptions has a low content in silica , while in explosive eruptions, it has a high Content in silica.  A volcano that erupts quietly has  magma that is low in silica. Low-silica magma has low viscosity and flows easily.  A volcano that erupts explosively has magma that is high in silica. High-silica magma has high viscosity, making it thick and sticky, thus it flows slowly.
        
             
        
        
        
One of the functions of scaffolds in tissue engineering is letter b. cells grow into the correct shape. Scaffolds used in tissue engineering have biomaterials with biological attributes <span>that will enhance cell attachment </span>and topography where cells morph and align.
