Studying the decay of radioactive isotopes in dead organisms helps scientists to identify fossilized remains. The ratio of C-12
to C-14 in the atmosphere is 1 x 1012. The table shows this ratio inside the body of three organisms. C12/C14 Ratio
Organism C12/C14 Ratio
E 8 x 1012
F 1 x 1012
G 4 x 1012
What can most likely be concluded from the above information?
Only Organism F is alive, and Organism G died before Organism E.
Only Organism F is alive, and Organism E died before Organism G.
Only Organism E is alive, and Organism G died before Organism F.
Only Organism E is alive, and Organism F died before Organism G.
We use the gas law named Charle's law for the calculation of the second temperature. The law states that, V₁T₂ = V₂T₁ Substituting the known values, (0.456 L)(65 + 273.15) = (3.4 L)(T₁) T₁ = 45.33 K
Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. While electron has mass of 9.31 ×10⁻¹⁹.
