and concentration in moles per mls while the weight was measured in grams. Time was also noted in hours and minutes. In dilute concentrations the celery looked turgid due to the hypotonic conditions they had more water in them. But as concentrations changed to hypertonic the samples shrunk because they had less water. Isotonic conditions were observed at a molarity of0.32M in the celery and at 0.36M in the potato. At 0M the potato and celery had percentage weight change of 17.07% and 9.93% respectively

from higher to lower concentration or lower to higher concentration is called hypotonic solution and hypertonic solution. Hypothesis: My Hypothesis for diffusion that the starch solution will be hypotonic and diffuse into potassium iodide (IkI). Hypothesis for osmosis is that each of the individual dialysis bags will increase because of the different concentration of the solutions. Which makes this and hypotonic experiment. Hypothesis for this experiment is that each of the four cylinders

Use the terms isotonic‚ hypotonic and hypertonic in the answer. (3 points) b.What would happen if a marine organism were placed in freshwater?

Cells Cell Theory- Cells are the smallest units of life All organisms are made of one or more cells All cells come from pre-existing cells Cells are organized Organelles- compartments that perform different functions in the cell Cells can be prokaryotic or eukaryotic Eukaryotes (Animals‚ plants‚ and fungi) Contain: Nucleus Membrane bound organelles Prokaryotes Nucleoid- region that contains DNA Flagellum Characteristics of Chloroplasts and Mitochondria (similar to Prokaryotic Cells)

graph‚ the subject that was used was the one that had the most consist numbers. What this means is that isotonic urine flow subject is not necessarily isotonic creatinine concentration subject. The kidney’s load for this was either a hypotonic‚ isotonic‚ alkalotic‚ or no solution at all. Based on the data above‚ some hypothesis were validated and other were not. In both the hypotonic and isotonic‚ the urine flow of the subjects increased as expected. This was due to the volume of water that the subjects

My First Lab Report: Diffusion and Osmosis To begin‚ this is my first time doing an experiment and a lab report for biology’s class. Although‚ it was a little hard at the beginning‚ my team and I got the hang of it and we finished it on time. It was actually kind of fun. There were three steps in the experiment: 3.1 A – Molecular Movement: In this session‚ I was observing a sample and determining if there was a movement or not. 3.1B –Diffusion through semi-permeable membrane dialysis tube: In this

Active transport: requires that a cell expend energy to move molecules across a membrane against the solute’s concentration gradient (the side where it is more concentrated) Feedback inhibition: Metabolic reaction is blocked by its products. A product acts as an inhibitor of one of the enzymes in the pathway to regulate metabolism. Centriole: a structure in an animal cell composed of microtubule triplets arranged in a 9+0 pattern. An animal usually has a pair of centrioles within each of its centrosomes
