Mass percent = % (m/m) = (grams of solute/grams of solution) x 100. Solution, not solvent so you need to add them. % (15 g / 15 g + 235 g) x 100 = 6.0% Na2CO3. An IV solution is prepared by dissolving 25 g glucose (C6H12O6) in water to make 500 mL solution.
âActivated B cells differentiate into either antibody generating factories called plasma cells that secrete soluble antibody, or into memory cells that survive in the body for years afterwards to allow the immune system to remember an antigen and respond faster upon future exposures.â ~ Wikipedia...
On average, red blood cells live for around 120 days. The spleen is the main organ where old red blood cells are destroyed. During the destruction of red blood cells, the heme groups turn into bilirubin and this substance is then captured by the liver and later excreted to the bowels as a part of bile.
