Two geologists were conducting a dig in a set of horizontal, undisturbed rock layers. They both discovered fossils in the same area, however, they would like to determine the exact age of their fossils. What is the BEST method for them to use to determine a more precise age of their fossils? SC.7.E.6.3A. Radiocarbon dating is the best way to determine the age of the fossils because it shows the amount of carbon decay in an organism that was once alive. B. Using the fossil record is the best way to determine the age of the fossils because the fossil record has not changed over time.C. The Law of Superposition is the best way to determine the age of the fossil because whoever dug deeper into the Earth obtained the older fossil.D. Using an index fossil is the best way to determine the age of the fossil because all fossils of the same species will be the same age.Tell me why you chose this answer

What does this symbol represent in terms of life cycles, and why is it drawn this way? O Sporophyte: It is a simple way of drawing the many spores within the sporophyte. O Multicellular organism: It is a simple way of drawing many cells to represent a multicellular life stage. O Spore: It is drawn this way to distinguish it from gametes, which are also single-celled. O Cell with cytoskeleton: It is drawn to show microtubules. O Nucleus with chromosomes: It is drawn to show two sets of chromosomes, making it diploid.
