<em>Radioactive tracers are useful in </em><em><u>determining medical problems.</u></em>
Answer: <em>B. Determining medical problems.</em>
Explanation:
Radioactive tracers are comprised of carrier particles that are reinforced firmly to a radioactive atom. These bearer particles shift incredibly relying upon the motivation behind the scan.
A few tracers utilize atoms that associate with a particular protein or sugar in the body and can even utilize the patient's very own cells.
Examples of radioactive tracer are - tritium, carbon-11, carbon-14 and oxygen-15 and so forth. Radioactive tracers are either injected in the body intravenously or orally.

Answer:
c.) increased glucose uptake to the liver from blood
Explanation:
During stressful conditions such as facing a mugger, the sympathetic system of the autonomic nervous system is activated. There is a release of stress hormones from the adrenal glands to produce the flight or fight response. One of the physiological events occurring during these conditions is the breakdown of glycogen into glucose in liver cells and the release of glucose into the blood. The release of glucose by the liver increases blood glucose levels. This is done to ensure glucose availability as fuel. There is no uptake of glucose from the liver cells under such emergency conditions.
