1. The cartoon suggests that the consequences of hyperinflation for ordinary Germans was that they were starving and did not have enough money to buy food because of the rise in prices. They may have had plenty of physical money‚ but it was not enough to pay for food since it had been devalued. It had resulted in people starving. The artist’s choice to use the metaphor of drowning to illustrate those consequence might be explained by the fact that the production of more money had become so much that

gradient. Prediction: When the potato cylinder is placed in a high water potential sucrose solution I think it will increase in mass‚ and length. This is because the solution has a higher water potential than the cells in the cylinder‚ water molecules will travel from a high water potential (The solution) to a low water potential (The potato cylinder) through a semi-permeable membrane by osmosis. More molecules will enter the cell then leave it‚ so the potato cylinder will swell‚ as the cells

from? Where are they moving to? I predicted that the potato would lose mass‚ and the mealworms would gain mass. I predicted that the BTB would lose mass. My last prediction was that the atoms are moving from the potato and into the mealworms. Steps for our procedure: 1.)Get container deep enough so mealworms can’t crawl out‚ with holes for them to breathe. 2.)Record container mass (empty)‚ Record container with mealworms‚ Record mass of potato and lastly record mass of BTB. Do all this before experiment

Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain

positively affected due to the concentration balance in their environment. Potato cells were used to see the affects of sucrose in different concentrations. In some concentrations a weight change was seen in the potato. Introduction In the osmotic concentration lab potatoes were used to see the affects of different concentrations of sucrose on the weight of the potatoes. Solanum tubersummore commonly known as the potato is the fourth most important food crop in the world. It originates from South

Theory/Hypothesis: In this experiment the researcher and their team will be performing tests on a catalyst (proteins found in potato) to see what will happen when the catalyst in a Hydrogen Peroxide reaction is treated with an acid before the reaction occurs. The researcher hypothesizes that the after treating the catalyst with an acid the amount of gas pressure produced will decrease

Osmosis and Water Potential in Potato Tissue Melanie Shadish‚ Rob Harris‚ Patricia Tellekamp Water appears to cross the differentially permeable membrane of potato cells by a process called osmosis. The measure of the energy involved in osmosis is called water potential. Since water must lose energy as it moves by osmosis‚ water must move from
