Answer: B.
Explanation:
cant be 'A' cause carbon 14 is found in any living organism and mammals are not the only living organism on this planet
cant be 'C' cause ancient plants still replenish carbon 14 molecules and it'd be impossible to now its age when its still alive
couldnt be 'D' cause yeah while alive organisms do absorb carbon 14 that still defeats the purpose of dating with the carbon 14 method cause its still also taking in carbon dioxide, so the carbon-14 molecules will just keep filling until the organism dies. the whole point of dating with carbon 14 is to measure its deplenish (dying) not continual replenish (living)
dont know if that makes any sense to you but yeah 'B' is the answer, if it isnt im stoopid but im not

Answer: conservative model
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.
chlorophyll is the answer
The correct answer is - A. A mutation that causes the code for the wrong amino acid.
The missense mutation is a type of mutation that affects the amino acids of the organisms. This mutation results in a codon that codes a different amino acid rather than the one that should be coded. Because of this it causes a synthesis of a protein with altered amino acid sequence during translation. This type of mutation is basically a change in one DNA base pair that results in the substitution of one amino acid for another one.
