to Volume ratio in Agar Introduction: What is an efficient way to maximize mass but minimize diffusion time in cell? Answer: An efficient way to maximize mass but minimize diffusion time in a cell is to increase its surface area. If you increase the surface area of a cell relatively to its volume‚ then the diffusion time will decrease. Materials: Agar cubes‚ bromothymol blue- pH indicator‚ vinegar‚ ruler‚ spatula‚ beaker. Methods: I used agar cubes as cell models. The agar was cut into blocks

In this study‚ three general media will be used for the detection of microorganisms on the equipment‚ personnel‚ raw materials and the finished goods. These are Potato Dextrose Agar (PDA)‚ Plate Count Agar (PCA) and Violet Red Bile Agar (VRBA) under the Univar brand. The amount of each prepared medium or dehydrated medium depends on the number of samples to be tested. PDA is usually used for the presence of yeasts and molds which are the most common food

Aim To measure how different concentrations of mythelin blue affects the rate of diffusion through agar jelly. Hypothesis The diffusion of mythelin blue is directly proportional to its concentration‚ hence as the concentration increases; the rate of diffusion increases too. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can

3DIFUSSION IN AGAR CUBES – LAB REPORT Research Question: What is the effect of surface area on volume ratio on the rate of diffusion of pigment from the agar cube measured by percentage volume of diffusion over time? Background Research: Diffusion is the passive movement of molecules or particles along a concentration gradient‚ or from high to low concentration regions. Essential towards living organism’s functions‚ as it describes how the nerve cells are able to communicate with each other‚ through

Acid into Different Sizes of Agar Blocks Aim: Investigating the relationship between the diffusion and the surface area to volume ratio‚ with agar and hydrochloric acid. Research Question: How does the difference in surface area to volume ratio affect the diffusion? Hypothesis: As the area to volume ratio increases‚ the time taken for a complete diffusion will also increase. Background Information: Agar is a jelly like substance and in this experiment‚ agar will be used is containing

Perhaps the most notable example of this manipulative phenomenon is Nazi Germany.

during WWI. Hitler gained his support in many ways. One way that Adolf Hitler gained support was through his book Mein Kampf. Another way that he gained the support that led him to gaining all of his power and control was the constant fear of the Communists gaining political power. Another way that Adolf Hitler gained all of his support was the Great Depression. Hitler’s book‚ Mein Kampf‚ which is translated to: “My Struggle” was a huge reason for the success of Adolf Hitler in gaining political
