Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space”. “Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent, then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution”. Hypothesis : When the quails’ eggs are immersed into 0% (distilled water), 5%, and 15% concentration of sodium chloride solution, the final mass of the quails’ eggs will increase.
Then, the eggshell started to soften. The next day the egg had a few bubbles on the eggshell, and the last forty-eight hours the egg was soft and mushy. The vinegar eroded the eggshell. When I took the egg out, I dropped the egg on the kitchen table and it bounced, instead of breaking like a regular egg. Afterward, I rubbed the eggshell which began to flake off like powder.
So water molecules will diffuse more into the solutions of higher concentration and the loss of mass is bigger. Water molecules from quails eggs will diffuse more into solution of higher concentration and less or no into solution of lower concentration 1. DATA COLLECTION Quantitative
The water keeps heating up above 100°C, building up more and more pressure. As it heats up the moisture in the kernel alters the starch stored inside forming a kind of jelly. Then the temperature can boost to 180°C. This increases the pressure inside the shell enormously, causing the shell to split and release the pressure. The drop in pressure causes the water in amongst the jelly-like starch to boil immediately, expanding by a factor of 1-2000 or more.
For B6 (Pyridoxine), my DRI was 1.3 mg. My intake was 0.8 mg, which is an intake of 60%. A deficiency of B6 vitamins leads to poor growth, skin lesions, decreased immune function, anemia, and neurological symptoms. In order to improve my intake of B6, I could consume more fortified breakfast cereals and also more meat. For B12 (Cabalamin), my DRI was
The results of the experiment showed that as the treatment time in the microwave went up, the germination rate of the seeds went down. The reason for this was the cells and enzymes in the seed were burnt. When all cells are not working properly in a organism the chances for it to survive is very slim. Introduction A bean seed is made up of three main parts the embryo, cotyledons, and seed coat. The embryo is a baby seed that is waiting to be grown.
Esteban Pellot Knowing Osmosis Introduction: Osmosis is the diffusion of water molecules that crosses the semipermeable membrane from a high concentration of water to a low concentration of water. The egg is a good product to demonstrate osmosis. Students can remove the shell of the egg to see how the osmosis works in the cell membrane of the egg, Problem: What happens when a student puts a egg in the solutions hypotonic, hypertonic, and isotonic? Hypothesis: A hypotonic solution will increase the mass of the egg, a hypertonic will decrease the mass of the egg, and a isotonic won’t affect the mass of the egg. Materials: The materials that are included in the lab are four jars, three eggs, water, vinegar, syrup, pencil or pen, paper, markers, and tape.
Salt affects yeast growth. If the dough is too salty, it will impede yeast growth because salt kills yeast.2 As a result, the bread rising is slowed down. Conclusion Dough rising can be affected by temperature, time, salt, quantity of water and yeast. B. Baking Aim Finding out the effects of baking on
Osmotic pressure is a colligative property, meaning that the osmotic pressure depends on the molar concentration of the solute but not on its identity. An experiment was carried out by immersing two quail eggs in 5 solution with different concentration to investigate the effects of solute concentration on the rate of osmosis. Objective: -To observe the effect of different concentrations of sodium chloride on a de-shelled chicken’s egg -To explain the effects in terms of osmosis Research question: How do different concentrations of sodium chloride solution affect the difference in mass of two de-shelled quail eggs which represents the rate of osmosis, gram/day of the two de-shelled eggs? Hypothesis: The closer the concentration of sodium chloride solution to the concentration of isotonic solution, the smaller is the difference in mass of quail eggs thus the smaller is the rate of osmosis. When the concentration of sodium chloride solution is closer to the concentration of the isotonic solution, the difference in mass of the quail eggs is smaller; the smaller is the rate of osmosis.
