Carbon-14 can be used to determine the age of a dinosaur egg. True False

Biology
1 answer:
kozerog [31]4 years ago
5 0

Answer:

FALSE

Explanation:

But carbon-14 dating won't work on dinosaur bones. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years.

Morgarella [4.7K]
<h2>The work of Charles Darwin and Alfred Wallace </h2>

Explanation:

C) uniform modification of genetic traits over long periods of time.

The theory of uniformitarianism  states that the natural phenomena and laws that are bringing about changes in the today's world are functioning in the same rate since the geological times. This idea of uniformitarianism was linked to biological sciences because according to Darwin and Wallace's observation, the uniform modification of genes among the population brought about the species diversity on the Earth.
