Answer:
3. Endotherms spend more energy on internal temperature regulation compared to ectotherms.
Explanation:
Ectotherms, are considered as cold-blooded animals (reptiles and amphibians), and are organisms that don't have the ability to generate enough heat to keep themselves warm. Endotherms, in contrast, do possess the ability to generate their own body heat.
Endotherms also called warm blooded animals (mammals) have the ability to regulate their body temperature by themselves. If the endotherms are in a cold place their body increases the metabolism and generates more heat. This will compensate for the cold outside.
The answer is the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.
C-14 and C-12 are carbon isotopes used to measure the approximate age of organic remains. C-12 is stable, and it does not break down into other elements over time. C-14 is not stable. It breaks down into N-14. But, in the body, the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions.
