Earth science multiple choice plz which statements about carbon-14 dating are true? check all that apply. carbon-14 decays into nitrogen-14. carbon-14 has a longer half-life than potassium-40. once a living thing dies, it no longer takes in carbon. carbon-14 dating is used to date very old volcanic rock. carbon-14 dating works for fossils as old as 50,000 years.

Answer;

-Carbon-14 decays into nitrogen-14.

-Once a living thing dies, it no longer takes in carbon.

-Carbon-14 dating works for fossils as old as 50,000 years.

Explanation;

-Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that.  

-Carbon dating is used by archaeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years.

-Carbon-14 has a half life of 5730 years, meaning that 5730 years after an organism dies, half of its carbon-14 atoms have decayed to nitrogen atoms.

A,C,E

Explanation:

Just took it

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
