It is not, 'imminent,' since the ozone layer in the atmosphere is slowly repairing itself. However, that being said, there is lots the human race can do to stop global warming. It may have more effect in 30 years time, but, if humans do enough, we can stop worrying. Renewable energy is a good idea to prevent global warming. Since most of it is generated from Co2 emissions from generating power. Electric cars are also good, because if we can make renewable energy (such as wind or solar power, or hydroelectric power for that matter) to power them, they will not produce emissions either.
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
Answer:
Due to the cost and resource input (specially the land) required for producing ethanol
Explanation:
In current time most of the ethanol is produced by fermenting corn, sugarcane or other plants at high temperature. In this process of fermentation, liquid bio fuel is produced.
These plants and crops require large area for cultivation and production along with huge inputs of fertilizers and water. As per an estimate , 3 gallons of ethanol require bushel of corn that intakes 800 gallons of water which is a huge cost to any nation or individual
Hence, scientist are finding new ways to create ethanol
Answer:
Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.
