- What kind of fossils were formed out of dinosaur remains and activities? Why do you say so? (Give three)Explain why it is difficult to use carbon-14 dating on 100-million-year-old dinosaur fossilsAn organism dies,and its body leaves an impression in mud. Over time, the mud hardens into rock, and the impression becomes a fossil. Which kind of fossil was formed? A) cast B) mold C) original material D) trace fossil
- According to this chart, which organism is most closely related to humans, why do you think so?In which type of rock are you most likely to find a fossil? a. basalt, a dark, fine-grained volcanic rock b. limestone, composed of sedimented calcium carbonate c. slate, a volcanically melted and cooled shale d. granite, which forms by crystallization of magma cooling below Earth’s surfaceWhich mechanism of fossil formation created a replica of an organism's original form? a natural cast b amber-preserved c permineralization d trace fossil
- In which type of rock are you more likely to find a fossil? a. basalt, a dark, fine-grained volcanic rock b. limestone, composed of calcium carbonate sediments c. slate, a volcanic melted and cooled shale d. granite, which forms by crystallization of molten rock below the surface of the EarthGive typing answer with explanation and conclusion What is parsimony? an element that decays from antimony, used for radiometric data of fossils. a way of building phylogenies that assumes the best tree has the highest statistical likelihood. a way of building phylogenies that assumes the best tree has the fewest character changes. a method for calibrating molecular clocks.Give typing answer with explanation and conclusion Question 2: Describe the Holocene epoch.
