Surface area

CONCLUSION An experiment was run to determine how a cell’s surface area to volume ratio affects its rate of diffusion. The proposed hypothesis was if a big surface area to volume ratio is something very desired by cells that need efficient and fast diffusion for their functioning (Oxygen, water, and waste), then the cube with the largest Surface area will have the most molecules diffused into the agar cube because the more surface area a cube have, the more molecules the agar cube is getting per minute and thus the rate of diffusion will be faster. The experimental data show that the bigger is the surface area to volume ratio, the bigger is the percentage volume of diffusion, so the rate of diffusion of pigment from the agar cube. The result of this lab was that the block with the highest class average…

At first, as I was examining the image of the swimmer, I thought about determining the area between the swimmer’s legs. At first, I thought that I could relate it to the area of a triangle, but later acquired the fact that the side length and height of an isosceles triangle cannot be equivalent, which meant that the area of a triangle would not fit this image. Figure 2 Created in Microsoft Paint In Figure 2, I have attempted to display an isosceles triangle to put in place of the swimmer's…

surface area vs rate of time Introduction: In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches. This experiment would benefit society because it informs the society the better way of consuming medicine or…

Demonstration of the Relationship between the Surface Area to Volume ratio on the rate of Diffusion Introduction: The surface area to volume ratio determines the rate of diffusion, the larger it is the faster nutrients will diffuse. Phenolphthalein acts as an acid-base indicator, turning pink in bases like NaOH and being colorless in acids like HCl. Using agar blocks as cells, a model was made to measure the rate of diffusion of different sized pink agar blocks changing to colorless ones.…

DIVERSITY AND SIZE Effect of Surface Area on the number of species in biodiversity. Yes, there is a relationship between species diversity and size, the smaller the habitat the less diversity of species there will be. Species diversity is the variety of organisms that make up a community It has two components: • SPECIES RICHNESS: is the total number of different species in the area • RELATIVE ABANDANCE: is the proportion each species represents in that certain measured area. we recognize…

concentration of a solution, presence of a catalyst, surface area, pressure of gases, temperature etc. These reaction rates may have positive or negative effects in our everyday lives. Today, I will be talking about how temperature, surface area and concentration can have a role in our everyday life. Firstly, a factor that affects the rate of a reaction that we see every day is temperature. We see temperature affecting rate of reactions through making food. For example, bread dough rises more…

Discussion Questions Which potato cube had the smallest surface area? During the investigation of part 1 and 2, it was indicating that the smaller the cell the larger the SA: V. Also, the larger the cell the less SA: V there is and this has a huge impact to the cell as it can’t get the nutrition it need which will result in death. The larger a cell gets, the smaller its surface area to volume ratio becomes. This is important because nutrients entering the surface of the cell must increase as…

Communal Areas Cleaning London Do you own a large commercial property, student property, flat share or office block? If you do, then you will have to address cleaning communal areas. The reason is because you must provide residents or visitors to such property with healthy living conditions that stand up to certain standards. You could try and take on such task on your own, but odds are it will be too large a job. By outsourcing the job to a communal areas cleaning company, you can take the…
