5. Before refrigeration, it was a common practice to salt meat in order to prevent bacterial growth and decay. Propose an explanation for why this process prevented bacterial growth. Diffusion Write a summary of your results and answer the questions. SUMMARY 1. Based on molecular weight, which dye would you predict to diffuse the furthest? Justify your choice. 2. What is the relationship between diffusion rate and temperature? Justify your statement with your results. What is your explanation for this relationship?

This assignment was tricky and I had a hard time figuring it out you place 3 bags each containing 20% sucrose solution in three different beakers. What will happen to the weight of the bag in all three cases? Mention which beaker has hypo, hyper and isotonic solution with respect to the solution of the bag. So I have to figure out what the beaker 1 bag is ___ tonic And the beaker is ___ tonic Then what’s the weight of the bag in each beaker 1,2,4 and in beaker 2 I have to know what’s the bag _____ tonic and beaker is _______ then the third beaker 3 the same _______ tonic and the _________ tonic Because in beaker 1 the bag is 20% sucrose And the beaker is 40% sucrose In beaker 2 the bag is 20% sucrose and beaker is 20% sucrose Then for beaker 3 Bag in beaker 3 is 20% sucrose Beaker 3, beaker has 10% sucrose Then I have to mention if the weight of the bag will increase decrease or remain the same. Also what the objective of a microscope is 50x and that of the…
Piston C Piston D Solution A Solution B Semipermeable membrane Above is a crude cartoon of a diffusion system. Two containers with solutions of sucrose in water are connected by a semipermeable membrane that is only permeable to water. Each container has a piston above it. Using this information answer the following. If the concentration of sucrose in solution A is 150mM and in solution B it's 2mM, which of the following would occur? al Piston D will feel an upward pressure. No diffusion will occur. Sucrose will diffuse from solution A to soluion B. Piston C will feel an upward pressure.
