Explain how the changes in abiotic factors during a hydrosere control the changes in species that are present A hyrdrosere is a plant succession which occurs in a fresh water lake. In time an area of open fresh water will dry out forming woodland. During a hydrosere there are many abiotic factors that change‚ which causes different species to inhabit the lake depending on the conditions they need to thrive and live successfully. There are many different stages that occur during a hyrdrosere

Lecture 5 Lizan A. Majeed Reading Paragraph Purpose Each paragraph in a text has a clear purpose. For example: The first paragraph introduces the topic‚ states the purpose of the text‚ or describes a problem or situation. The body paragraphs develop arguments‚ try to persuade‚ suggest solutions‚ or describe developments. The final paragraph concludes‚ evaluates‚ or discusses consequences. Identifying the purpose of each paragraph helps you understand the text and decide where

Distinguished ladies and gentlemen. Acid rain is becoming a widespread problem around the world. The amount of acid in rain has dramatically increased in the past decade in certain areas like America and Europe by 70%. How is it caused? It is formed by the chemicals in the process of burning fossil fuels mixing with the moisture in the Earth’s atmosphere. Acid rain come in two forms‚ wet and dry. Dry deposition‚ a more accurate term for acid rain‚ can appear to be snow‚ hail or other dry particles

reactions that are essential for life. Without enzymes life processes‚ and life in of itself‚ would not be possible. Enzymes are also special because very little of the actual enzyme is actually used up in the reaction. In this lab two different factors‚ temperature and pH‚ were tested to see what type of effect they would have on catalase‚ a potato enzyme that synthesizes H2O2. The data my group collected supported one hypothesis‚ that an acidic environment would not be conductive to enzyme behavior

Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops

Essay March 28‚ 2014 ACID RAIN ENVIRONMENAL EFFECTS What is acid rain? It’s a rain or any other form of precipitation that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react with the water molecules in the atmosphere to produce acids. The most obvious environmental effect of acid rain has been the loss

Humans (scientists) have found ways to alter the balance of nature. Genetically engineered individuals are considered to have more potential and are more favored in terms of employment and career options (companies determine the positions of applicants

Acid rain is rain that has become acidic‚ because of air pollutants in the atmosphere. Rain has a normal pH level of around 5-5.5 which is only slightly acidic. 7 on the pH scale is the neutral and anything below that is considered acidic. Acid rain has a pH level around 4 which is 10 times more acidic. Acid rain can fall in many different ways and has many effects on the environment. Acid rain is caused by air pollutants in the atmosphere. These air pollutants are mainly from man made resources

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a
