The answer that best represents the above characteristics would be <u>A.) Down syndrome </u>
Answer:
Potassium-40
Explanation:
Potassium-Argon dating is the most efficient radioactive dating method in order to determine the absolute age of the fossils. It involves the decay of unstable Potassium-40 (K-40) into a stable Argon-40. The half-life of this Potassium-40 is approximately 1.3 billion years, so it is very much helpful to date the rocks that are of about 4.6 billion years to 100,000 years old.
Thus, the K-40 radioactive isotope would be the best to determine the exact age of the fossil that is found in the rocks that are about 600 million years old.
The Krebs cycle can be used to make many various intermediates that can be siphoned off into other pathways. Mainly though, it makes the electron carriers NADH and FADH2 which can then be used in the electron transport chain to generate ATP.
In ancient times, people did not know the causes or carriers of diseases. Since they could not come up with a scientific reasno with thier current technology, they diecided that the gods sent the diseases as a punishment for thier sins.
