You did not included your list of selections. Some general properties ascribed to DNA are storage and expression of information and variables through mutations. Replication, Transcription, Translation and Mutagenesis are the major functions of DNA in a cell. DNA nucleotides contain deoxyribose. DNA is double-stranded in the conservative mode, the original double Helix remains a complete unit and the new DNA double Helix is produced as a single unit. In the double=stranded DNA, Hydrogen bonds hold one complimentary strand to the other.
Hope this helps, I love Science.
Answer: The fossil is 11459 years old.
Explanation:
Half-life of carbon-14 = 5700 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the age of the sample:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = ![1.21\times 10^{-4}\text{years}^{-1} t = age of sample = ? a = let initial amount of the reactant = 100 g x = amount decayed = 75 g a - x = amount left after decay process = 100 - 75 = 25 g Now put all the given values in above equation, we get [tex]t==\frac{2.303}{1.21\times 10^{-4}}\log\frac{100}{25}](https://tex.z-dn.net/?f=1.21%5Ctimes%2010%5E%7B-4%7D%5Ctext%7Byears%7D%5E%7B-1%7D%0A%3C%2Fp%3E%3Cp%3Et%20%3D%20age%20of%20sample%20%20%3D%20%3F%0A%3C%2Fp%3E%3Cp%3Ea%20%3D%20let%20initial%20amount%20of%20the%20reactant%20%20%3D%20100%20g%0A%3C%2Fp%3E%3Cp%3Ex%20%3D%20amount%20decayed%20%3D%2075%20g%0A%3C%2Fp%3E%3Cp%3Ea%20-%20x%20%3D%20amount%20left%20after%20decay%20process%20%20%3D%20100%20-%2075%20%3D%2025%20g%20%20%3C%2Fp%3E%3Cp%3ENow%20put%20all%20the%20given%20values%20in%20above%20equation%2C%20we%20get%0A%3C%2Fp%3E%3Cp%3E%5Btex%5Dt%3D%3D%5Cfrac%7B2.303%7D%7B1.21%5Ctimes%2010%5E%7B-4%7D%7D%5Clog%5Cfrac%7B100%7D%7B25%7D)
