Aim: To investigate the effect of one environmental factor on the phenotype of pea plants Background Information: Pea seeds are available with identical genetic information for height - tall or dwarf peas. These seeds can be used to demonstrate the effect of the environment on the final height of the pea plants. Tall or dwarf peas can be grown in identical conditions where all variables are kept constant apart from one environmental factor. Any differences in the height of the pea plants will be

The revolutionary thinking has waged a battle in opposition to the low-dense suburban intensification or sprawl. Yes I agree to the reality that the Urban Sprawl is behind all the issues posing danger to the environment. What are the associated issues? Can there be planned solution for a good cause? Sprawl generally conjures image of strip mall and mega store‚ traffic congestions‚ long commuting‚ lost open spaces‚ contamination‚ crowded school‚ higher tax‚ and the termination of downtown shopping

The Hazardous Effects of Pollution to the Environment and Human Health Abstract Pollution is the introduction of contaminants into the natural environment that causes adverse change. It can take the form of chemical substances or energy. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. It is any discharge of material or energy into water‚ land‚ or air that causes or may cause acute (short-term) or chronic (long-term) detriment

Positive Effects of Volcanos Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land‚ the creation of valuable natural minerals and ores‚ and the enhancement of countries’ tourism potential. Creation of new land: Volcanic activity can result in the creation of new land‚ when material from within the earth’s crust is ejected in the form of molten liquid‚ then cools and solidifies to created

5. Human activity also impacts on waterways. Chemical monitoring and management assists in providing safe water for human use and to protect the habitats of other organisms Identify that water quality can be determined by considering: * concentrations of common ions * total dissolved solids * hardness * turbidity * acidity * dissolved oxygen and biochemical oxygen demand Water quality is commonly defined by its physical‚ chemical‚ biological and aesthetic (appearance and

Some people say human activity makes the Earth a better place to live. But actually as we want more comfort and fancy life‚ we are actually damaging the Earth. There are three general ways to harm the Earth‚ Air‚ Soil and Ocean and we are damaging all three of them. Firstly‚ we ride our cars to go somewhere. In my opinion‚ cars are mainly responsible for air pollution. Air pollution is one of our most serious problems because we breathe everyday and even animals and plants need clean air. We all

Human Impact on the Environment Every living thing has an impact on its environment. Therefore a human impact on the environment is inevitable. By simply existing‚ all species - including ourselves - will imprint their mark on the world around them. What differentiates us from other species is our ability to greatly overburden our environment with very few limits. The information regarding our human impact is vast and impossible to cover in one article but I will attempt to cover a basic overview

Investigating the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed
