The amino acids are provided in 10 mg/mL amounts. Complete dilution calculations to determine how to create a range of five concentrations between 0-2 mg/mL and record them in the lab notebook. To do this, pick five amino acid concentrations (within the range) and calculate how many mL of the 10 mg/mL amino acid solution is needed in order to make your chosen concentrations if the total volume of your solutions is 5 mL Required:
How many mL of water will you need to add to each of the dilutions?

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
