Oxygen

 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…

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…

Let me say it right now. Everything you thought was the limit of human kind is wrong. The strongest weapon is not the nuclear bomb. The strongest material is not steel. Your brain is not the fastest computer on the earth. The sky is not the limit. Humanity has not reached it full potential. How…

The effect of nutrition on the activity of Artemia franciscana Intro: In most ecosystems, the availability of nutrition is the most limiting factor of population growth and activity (Fábregas, 1997). If there is a lack of food resources in a community or a lack of certain specific dietary requirements, then the physiology of that community…

Antoine-Laurent Lavoisier (lah vwah ZYAY) was one of the best-known French scientists and was an important government official. His theories of combustion, his development of a way to classify the elements and the first modern textbook of chemistry led to his being known as the father of modern chemistry. He contributed to much of the…

Rapid Fire Progression Phenomena Brian J. Rocker Jr. American Military Institute Abstract Fire fighters are killed every year due to lack of knowledge on the job.

So, what am I going to talk about? Well, how about I make this easy for you and just spit it out? -pause- *sigh* Well fine then, it you want a proper introduction, then here it is: Have you ever decided to just go for a nice walk outside to get some exercise and enjoy…

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…
