Null Hypothesis: There will be no difference Part 1- Post Lab Question If a cell contains a set of duplicated chromosomes‚ does it contain any more genetic information than the cell before the chromosomes were duplicated? No‚ because if it is duplicated‚ it would have the same number of chromosomes unless there was a

AP Bio Essay #1 To address this problem created by the lab tech‚ I would set up an experiment like the one we did in AP biology to identify the molarity of the unknown sucrose solutions. First I would pour an equal volume of each solution into beakers labeled A‚ B‚ C‚ and D. I would also have a beaker of the same amount of distilled water to serve as a control for the experiment. Then I would obtain several baby carrots‚ 4 per beaker. I would mass the groups of 4 potatoes before placing them

Background Information Part 1 In the first part of the enzyme lab‚ we mixed a substrate and an indicator with an enzyme. There was also a neutral buffer in each of the chemical mixtures. The neutral buffer regulated the pH to around 7. We got a color palette and once we mixed each together‚ we observed and saw a change in the color of the substance. The darker and more brown the substance got‚ the more oxygen produced by the reaction. Our results showed that amount of oxygen produced increased
