Many researchers are trying to find new renewable energy sources to help diminish carbon emissions‚ which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many

Work Renewable and Non-renewable energy sources &Fuels: Renewable energy comes from natural sources that are constantly and sustainably replenished. The most common renewable energy sources are biomass‚ hydroelectric‚ geothermal‚ wind power and solar power. Sunlight is the source of most renewable energy power; the sun can be used to produce solar energy which is electricity for heating‚ cooling‚ lighting homes and transportation.

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

1. Where have you been today? Describe the places! I started my day off with a wonderful brunch over at my best friend’s house. Her house is very pretty and bright‚ especially the outside.

Nuclear Energy There are many advantages and disadvantages of using nuclear power. Nuclear power is said to prevent power outages that happen in areas without nuclear power. For an example‚ if we were using hydroelectricity and the dam suddenly malfunctions‚ then we won’t have electricity until someone fixes the dam‚ and that would be difficult if it happened in the middle of the night. However‚ on the other hand‚ nuclear power is also considered toxic and it pollutes the Earth with harmful and

THE ORGANELLES OF EUKARYOTIC CELLS . The difference between Prokaryotic and Eukaryotic Cells is organelles‚ membrane enclosed structures that perform specific duties. The most important of all is the “nucleus‚” this holds the DNA and is surrounded by a double membrane. The Prokaryotic lacks a nucleus which is not partitioned from the other cells by membranes. The region between the nucleus and plasma membrane is called cytoplasm and in the Eukaryotic cell it consists of various organelles
