When will a fossil be used in finding the absolute age of rocks?(1 point) Responses if it existed for a long period of time and in a small area if it existed for a long period of time and in a small area if it existed for a limited period of time and in a wide area if it existed for a limited period of time and in a wide area if it existed for a limited period of time and in a small area if it existed for a limited period of time and in a small area if it existed for a long period of time and in a wide area if it existed for a long period of time and in a wide area
A fossil can be used in finding the absolute age of rocks if it existed for a long period of time and in a wide area.
(1 point) Responses the ratio of protons to neutrons in carbon-14 the ratio of protons to neutrons in carbon-14 the difference between the amounts of carbon-12 and carbon-14 the difference between the amounts of carbon-12 and carbon-14 the ratio of carbon-12 to carbon-14 the ratio of carbon-12 to carbon-14 the difference between the number of protons and neutrons in carbon-14
A fossil cannot be used to determine the absolute age of rocks based on the points provided. To determine the absolute age of rocks, other methods like radiometric dating (e.g., using the ratio of carbon-14 to carbon-12) or other isotopic dating techniques are used.
Use this paragraph: The half-life of carbon-14 is 5,700 years. A certain sample of wood has 20 grams of carbon-14 when it is alive. How many grams of carbon will it have after 5,700 years? (1 point) Responses 2 grams 2 grams 5 grams 5 grams 40 grams 40 grams 10 grams
After 5,700 years, half of the carbon-14 in the wood sample will have decayed. Therefore, it will have 10 grams of carbon-14 remaining.
Which statement best describes why most individual organisms never fossilized?(1 point) Responses Conditions for fossilization are rare. Conditions for fossilization are rare. Only organisms with hard parts fossilize. Only organisms with hard parts fossilize. Only organisms that lived in the ocean fossilize. Only organisms that lived in the ocean fossilize. Chemicals that fossilize organisms are rare.
