Surface Area to Volume Ratio and the Relation to the Rate of Diffusion Aim and Background This is an experiment to examine how the Surface Area / Volume Ratio affects the rate of diffusion and how this relates to the size and shape of living organisms. The surface area to volume ratio in living organisms is very important. Nutrients and oxygen need to diffuse through the cell membrane and into the cells. Most cells are no longer than 1mm in diameter because small cells enable nutrients and oxygen

This concept applies to cells and reaction rate because cells need to absorb their food‚ water and oxygen through their cell membrane and depending

different areas‚ and especially in the making of ships. The surface area that is touching the water of the ship is very large‚ due to the shape of the hull‚ and that‚ beside the density of the ship‚ is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing position in the water. But how does the surface area of an object

How does varying the surface area to volume ratio (2.0046: 1‚ 1.4923: 1‚ 0.9425: 1‚ 0.6480:1‚ 0.5970:1) affect the amount of heat lost over a period of 6 minutes of 50cm3 water with a temperature above 50? b. Prediction and Hypothesis. Make a prediction about what you expect to be the outcome. Explain your prediction using scientific ideas. I predict that the bigger the surface area to volume ratio‚ the lesser the heat will be lost. And the smaller the surface area to volume ratio the more

·Substrate Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato‚ you make more Catalase molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between the enzyme and the substrate. Catalase is an enzyme found in food such as‚ potato. It is used to break down a poisonous by-product of metabolism called

How to Logically Solve a Rubik’s Cube Kenneth Cason First‚ as with any problem‚ it is important to understand what your objective is. In the case of the Rubik’s Cube‚ the main goal is to arrange the pieces in such a way that each side is the same color. Next lets luck at the structure of a standard 3x3 Rubik’s Cube. It is a cube composed of 6 sides‚ each side composed of 9 stickers (3x3). There are 8 corner pieces‚ 12 edge pieces and 6 center pieces (one on each side). It is also important to note

The potato is a starchy‚ tuberous crop from the perennial Solanum tuberosum of the Solanaceae family (also known as the nightshades). The word may refer to the plant itself as well as the edible tuber. In the region of the Andes‚ there are some other closely related cultivated potato species. Potatoes were introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world’s cuisine. It is the world’s fourth-largest food crop‚ following rice‚ wheat and maize
