Oxygen

Research Question: Investigate the rate of photosynthesis of an elodea plant by measuring the amount of oxygen that is produced by it. Variable: Independent Variable: The Independent variables are the different colors of cellophane paper that are wrapped around the 15 test tubes. The 5 different colors are green, blue, red, yellow and one without…

 Intro/Background In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CA, and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of 02 or the consumption of CA. All the oxygen within…

Plants ; likely the most neglected being on this planet. Peoples walk past works and cut them down but nobody of all time thinks about what they do for us. what the universe would be if there was ne’er any workss or photosynthetic beings. If the universe ne’er had these organisms the universe would be…

In this experiment factors of dissolved oxygen as well as depth were manipulated to examine their effects on both opercula beats per minute as well as breaths taken by the test specimen Corydoras aeneus per hour. The oxygen concentration was decreased by bubbled nitrogen gas through the water until it became more abundant that the…
