Answer 1

Hot nodules show increased activity and are less likely to be malignant, while cold nodules show decreased activity and have a higher likelihood of being malignant.

Step-by-step explanation:

Thyroid nodules are evaluated using radioactive isotopes and nuclear scans. They are distinguished as being either hot or cold based on their ability to absorb the radioactive material. Hot nodules show increased activity and are less likely to be malignant, while cold nodules show decreased activity and have a higher likelihood of being malignant.
