olya-2409 [2.1K]

Answer;

-PET scan

A PET scan uses radioactive markers in the blood to monitor blood flow and metabolic activity via x-ray

Explanation;

-A positron emission tomography (PET) scan is an imaging test that helps reveal how the tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.

-A PET scan is used to diagnose certain health conditions, to plan treatment, to find out how an existing condition is developing, and to see how effective a treatment is.

-In a PET scan, a machine detects radiation that is emitted by a radiotracer. A radiotracer consists of radioactive material that is tagged to a natural chemical, such as glucose.

Lesechka [4]

Answer:

decreases a plant’s weight

Explanation:

Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.

Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.

Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.

Hence, the correct answer is "decreases a plant’s weight".
