Effect of Industrial Expansion on the ecosysytem. Pollutants given off by various industries and factories are often considered to be one of the prime factors contributing to air‚ water and soil pollution. According to the Environmental Protection Agency (EPA)‚ it has been estimated that industrial pollution is responsible for almost 50 percent of the pollution present in the United States. There are various wide-ranging effects‚ as well as serious consequences‚ of industrial pollution on the ecological

the late century‚ extinction becomes common topic in our daily discussion and debates. An average of 27‚000 species is currently extinct each year and there is a possibility of 22% of extinction in the overall species if action is not taken. Animal extinction is due to human immorality and irresponsible behavior just for their own benefits. Since the year 1600‚ a total of 83 mammals species are known to have become extinct. Wildlife population depleted the trade in live animals‚ damaged habitats

Natural Selection and Heritability: From Butterflies to humans Created for SPICE by Amy Non and Carmella O’Steen March 2007 Natural Selection Simulation Lesson 2 (as modified from Robert Gendron’s “Simulating Natural Selection” for Introductory Biology Lab College Course‚ Indiana University of Pennsylvania) Key Question(s): What is natural selection? How does natural selection change allele frequencies over time? Does natural selection work differently on large versus small populations

Natural selection Natural selection is one of the basic mechanisms of evolution‚ along with mutation‚ migration‚ and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To find out how it works‚ imagine a population of beetles: 1. There is variation in traits. For example‚ some beetles are green and some are brown. 2. There is differential reproduction. Since the environment can’t support unlimited population growth‚ not all individuals

Natural Selection Paper Natural selection is considered one of the most important processes for a variety of species and the environment which allows the fittest organisms to produce offspring. To prevent a species from extinction‚ it is necessary for them to adapt to the surrounding environment. The species which have the ability to adapt to new surroundings will be able to pass their genes through reproduction. Within the process of natural selection‚ it is possible for the original genetic make-up

Extinct Species: Dodo Bird Joseph Sulaiman Pd.2 The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. Related to pigeons and doves‚ it stood about a meter (3.3 feet) tall‚ weighing about 20 kilograms (44 lb)‚ living on fruit‚ and nesting on the ground. The dodo has been extinct since the mid-to-late 17th century. It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history and was directly attributable

Natural Disasters We have all seen the awful effects of a flood or an earthquake - if we’re lucky only on the news. About 75 percent of the world’s population live in areas affected at least once by earthquake‚ tropical cyclone‚ flood or drought between 1980 and 2000 (Reducing Disaster Risk UNDP report‚ 2005). What causes natural disasters? First we need to get a bit technical. Natural hazards and natural disasters may sound like the same thing but there is a small but vital

GROWN-UP’S ARE A DIFFERENT SPECIES Understanding grown-up’s is never easy. They hold on to things that were. They wonder what’s to come... and then they think they know everything just because they have experience! Really!! Antoine de Saint said: “Grown-ups never understand anything for themselves‚ and it’s tiresome for children to be forever explaining things to them”. For example: Have you ever seen a grown-up just after they got a new cell phone? They’re too scared to explore the menu options
