sINTRODUCTION What are Carbon Credits? A carbon credit (often called a carbon offset) is a financial instrument that represents a tonne of CO2 (carbon dioxide) or CO2e (carbon dioxide equivalent gases) removed or reduced from the atmosphere from an emission reduction project‚ which can be used‚ by governments‚ industry or private individuals to offset damaging carbon emissions that they are generating. How are Carbon Credits used? Carbon credits are associated with either removing existing CO2 or

THE MOLECULAR BASIS OF INHERITANCE I. History A. Discovery of “transformation” – a change in genotype and phenotype due to the uptake of external DNA by a cell 1. Griffith 1920s did experiments with Streptococcus pneumoniae (p294 fig16.2) a. took two strains of S. pneumoniae‚ one virulent‚ one not b. heat killed virulent strain‚ then mixed them with the living nonvirulent strain c. living nonvirulent strain became virulent d. nonvirulent strain took on virulent strain’s DNA became virulent

Carbon Nanofibers Carbon nanofibers can simply be known as nanostructures with bonded carbon atoms that has a molecule composed entirely of carbon in shape of hollow sphere‚ ellipsoid or tube. The layers are usually wrapped up to form carbon nanotubes. Nanotubes are usually constructed with length-to-diameter ratio of up to 132‚000‚000:1. Basically‚ carbon nanofibers can be used very commonly in future as the technology for it is really taking its shape. It can be used for sensors‚ bone growth‚

2013 Carbon Footprint Until very recently‚ most people had never heard of a “carbon footprint.” Now‚ all of a sudden‚ the phrase is hard to avoid. In an age of slick slogans‚ fast fashions and fickle fads it’s easy to assume that this is just another quirky passing gimmick. But it could well be the most important concept of our time. A carbon footprint is the amount of carbon dioxide (CO2) emitted as a direct or indirect result of an activity (Yarrow‚ Joanna. How to Reduce Your Carbon Footprint:

Carbon dioxide is the main pollutant that warms our planet Earth. Living things produce carbon dioxide when they breathe. However‚ carbon dioxide is considered to be a harmful pollutant when linked with any vehicle‚ trains‚ power plants‚ as well as other various human activities that involve burning fossil fuels such as gasoline and natural gas. Studies have shown that In the past 150 years‚ such activities have released enough carbon dioxide into the atmosphere to raise its levels higher than they

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4 Valence electrons: 4 Property: Non-metal Abundance: Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon: The Covalent Bond

ABSTRACT We are in debt to Carbon Dioxide (CO2) and other green house gases for our presence on earth. As they help in stabilizing temperatures to levels sustainable for organic life – by what is known as green house effect. In modern times burning of fossil fuels like coal‚ oil‚ and natural gas combined with fast deforestation has led to unprecedented level of green house gas emission. Here came in to existence the concept of Carbon Emission Trading developed during the Kyoto Protocol in 1997
