use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made their appearance and started engaging in their photosynthetic reactions‚ large amounts of oxygen were suddenly released in the atmosphere. This lead to what is known as the Great Oxygenation Event

Carbon tax is an environmental tax levied on the carbon content of fuels. It is a form of carbon pricing. Carbon is present in every hydrocarbon fuel ‚ such as coal‚ petroleum‚ and natural gas. It is then released as carbon dioxide (CO2) when they are burnt. In contrast‚ non-combustion energy sources—wind‚sunlight‚ hydropower‚ and nuclear—do not convert hydrocarbons to CO2. CO2 is a heat-trapping "greenhouse" gas. Scientists have debated and discussed the potential effects on the climate system of

Carbon Nanotubes Abstract Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology‚ electronics‚ optics‚ and other fields of materials science. They exhibit extraordinary strength and unique electrical properties‚ and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member

TOMATO PLANT 1) Seed: Tomato seeds are small‚ flat and disk shaped and about 1/8 inch wide. They contain two energy storage organs called cotyledons and an embryo encased in a hard outer shell called the seed coat. The seed is the dormant or resting stage of the plant life cycle. When young tomato plants are damaged‚ they tend to go into a dormant‚ survival stage in which plant growth is delayed for a while. Frost damage is something to look out for when planting tomatoes early on in the season

A world without plants Plants; probably the most ignored organism on this planet. People walk past plant and cut them down but nobody ever thinks about what they do for us‚ what the world would be if there was never any plants or photosynthetic organisms. If the world never had these organisms the world would be a desolate place. There would be no oxygen‚ atmosphere‚ or food. We inhale air unconsciously every day. By taking in air‚ we absorb oxygen and discharge carbon dioxide in the process of

Carbon Footprint The term “carbon footprint” refers to the amount of carbon dioxide we emit into the air every year. C02 is produced by many sources and is the gas responsible for Global warming and alarming changes in our climate. As we use our resources‚ the negative impact on our environment increases. The more C02 emitted in the air the more our ozone layer is affected. C02 is a natural gas and is always being emitted and absorbed to and from the air. There is a certain amount of carbon

In this investigatory project its main purpose is to find out if how can charcoal be used as a filter and how does it work? Since charcoal is made out of carbon. According to Encyclopedia: "The use of special manufacturing techniques results in highly porous charcoals that have surface areas of 300 - 2‚000 square meters per gram.
