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...
Sickle cells only live for about 15 days, while normal hemoglobin can live up to 120 days. Also, sickle cells risk being destroyed by the spleen because of their shape and stiffness. The spleen is an organ that helps filter the blood of infections and sickled cells get stuck in this filter and die.
