Coding sequence is used to build proteins from amino acids. Each amino acid has a specific 3-base sequence known as codons. Since proteins are very important in our lifes and many biochemical processes, the coding sequence is very important. A change in the coding sequence (mutation) may result in the wrong protein being produced. Some incurable human diseases are as a result of changes in coding sequence
Atmospheric carbon (as carbon dioxide) consists of both C-12 (mostly) and C-14 (actually there's a third but forget it for now). Plants use both isotopes in the formation of sugars. When the plant dies no more C-14 comes in and what C-14 is there (at death) slowly converts into C-12. Note that animals eat plants (or animals that eat plants) until they die ... after that the same isotope decay occurres. The half-life of C14 is about 5700 years, so dating of objects greater than 5 - 10 half-lifes becomes very difficult. So 40 - 60 000 years tops. Forget coal.

Human life - chemical energy from the food we've eaten is what keeps us alive.
Everything around him: people, things (still lifes), environment...
A living thing that can carry out lifes process independently. please add corrections if I'm wrong.
The iPod changed many peoples lifes because now people can hear to music whenever and wherever they want too. Without having to carry a big CD player.The iPod changed many peoples lifes because now people can hear to music whenever and wherever they want too. Without having to carry a big CD player.
Jesus is our Creator, and he made the world. He has EVERYTHING to do with our lives. He's the most kind, caring, and generous person there ever was.
Ict has changed out lifes by improving them.
Each isotope has a different rate of radioactive disintegration characterized by the half-life, the time necessary to reduce by half the number of atoms.
