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

water and Methylene blue solution and leave it undisturbed. The blue solution turned clear and when we added the yellow food coloring it turned an orange color. The solution then turned dark blue once the solution was shaken vigorously. This reaction occurred because the oxygen oxidized the methylene blue.In the oxidized state the methylene blue shows a deep blue color this corresponds with what happened first in our lab when the materials where mixed. In the reduced state methylene blue turned to

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

The effect of molecular weight on the rate of diffusion was assessed using Methylene Blue (320 g/mol) and Potassium Permanganate (158 g/mol). This subjects have varying molecular weight‚ one higher than the other. It is important to note whatvis Molecular Weight. MW is the sum of the mass of each constituent atom multiplied by the number of atoms that element in the molecular formula. With the aid of agar plates‚ we put some substrate on it for purpose of observation. Having a time-interval

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
