zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

Duodenum • The section of the small intestine immediately below the stomach. Digestive juices from the gallbladder‚ liver‚ pancreas and gland cells in the intestinal wall mix here with chyme to continue with digestion Pancreas • As a digestive organ‚ the pancreas secretes hydrolytic enzymes and a buffer into the duodenum. The pancreas also acts as an endocrine gland Liver • Regulating blood sugar levels • Converting lactic acid to glycogen • Lipid regulation • Deamination of amino acids

and flaws within human reflexes. · Size of the liver cubes: As the liver cubes needed to be cut by each individual group‚ the sizes between the groups may have varied. The required size for the lamb liver cubes was 1cm3 ‚ however the task of cutting the liver into all the same was extremely difficult‚ keeping the size consistent throughout the nine other groups would be close to impossible. It was important to have a consistent size in the liver pieces‚ this may have been achieved by a number of
