I will give 25 points and make them brainlest if they solve this.
A carbon atom that is a part of your body could very well have been part of a dinosaur millions of years ago. What BEST explains this?
A The carbon atoms that are found in current living things are developed when the organism is produced.
B Carbon atoms found in current living things are the same carbon atoms that have always been a part of living things, they are just recycled.
C This could not be explained because carbon found in our bodies could not have a part of any previous organism.
D Carbon atoms are genetically passed through the evolution of organism.

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
