Sammy Hassan Mrs. Droege Biology‚ 4B September 7‚ 2007 Surface Area to Volume Ratio S.Hassan‚ September 7. 2007 AISJ‚ Jeddah Saudi Arabia Surface area is known to be beneficial to keeping organisms alive it allows huge organs such as the intestines to fit in a small area by being coiled and packed together tightly. This experiment looked if the surface area to volume ratio affected the speed of a chemical reaction. For this experiment‚ a film container was filled one-half full with

Applications of Differentiation 1. If a line y = x + 1 is a tangent to the curve y2= 4x ‚find the point the of contact ? 2. Find the point on the curve y = 2x2– 6x – 4 at which the tangent is parallel to the x – axis 3. Find the slope of tangent for y = tan x + sec x at x = π/4 4. Show that the function f(x) == x3– 6x2 +12x -99 is increasing for all x. 5. Find a‚ for which f(x) = a(x+sinx)+a is increasing 6. Find the intervals in which the function f ( x ) = x3 - 6x2 + 9x + 15 is

10cm and a width of 3cm. Then find the volume of the box and the total surface area of the paper used to make the box. T.S.A: 5 rectangles and 4 squares 5 x L x W + 4W = 5 x 10 x 3 + 4 x 9 = 186cm Volume: 5 rectangles and 4 squares L x W x H = 10 x 3 x 3 = 90cm Q2. Make another box with the same general shape‚ but chose a different length and width. Then find the volume of the box and the total surface area of the paper used. T.S.A: 5 rectangles and 4 squares = 5 x 4 x 2 + 4 x 4 = 40

depend upon the efficient transport of substances into‚ out of‚ and throughout living cells. The process of diffusion can be easily visualized by adding a drop of blue food coloring to a glass of water. Initially‚ the food coloring remains in a small area in the water‚ dying it a dark blue. Over time‚ the molecules of food coloring collide with each other‚ and with molecules of water‚ and the food coloring eventually disperses throughout the entire glass of water‚ resulting in a light blue color in
