In Echolocation: Volume Control by Amanda Tromans‚ she explains how some animals and machines use sound to locate things instead of using vision like others. For example‚ bats‚ dolphins‚ and submarines all do this but with a few differences. This paper is more like a review so it does not show specific steps. She explains in the beginning why those exactly use echolocation; this is basically the use of echoes and soundwaves. Those echoes and soundwaves are bounced off many objects so they can get

The Invention of the White Race‚ Volume I by Theodore w. Allen Theodore William Allen was an independent writer‚ working intellectual and activist. He is known for his works that contributed a great deal in theory that is critical of race and the origins of it. He wrote a lot on concepts of racism and the special privileges of the white people. His vast interest in racial segregation‚ which derives from a made up concept is what perhaps‚ pioneered this work on “The Invention of the white Race”.

was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be repeated for better

In Parts A and C‚ the relationship between surface area and volume was investigated. Plasticine was formed into a cube and a sphere; both shapes were cut in half. It was found that plasticine volume should not vary‚ two halves have a greater surface area than a whole‚ and cubes have a greater surface area than spheres of the same volume. In Part B‚ the relationship between diffusion and surface area to volume ratio was investigated. Three agar-phenolphthalein-sodium hydroxide cubes of different sizes

Surface area / Volume ratio Experiment Introduction: 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 to diffuse into the cell quickly and allow waste to diffuse out of the cell quickly. If the cells were any bigger than this then it would take too long for the nutrients and oxygen to diffuse into
