Their shapes fit snugly together
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.
The type of reproduction that takes place in archaebacteria and eubacteria is Binary Fission.

PART B: My Own Masterpiece!
Activity 1: What are your true colors?
Use the given fictional genes of different colors to predict the phenotype ratio
and genotype ratio. Color each tile in the Punnett square corresponding to its
phenotype. An example is already given as your guide.
