The answer is "PET scan" or "PET-CT".
PET scan or positron emission tomography uses the technology behind conventional CT scans but performs to quantify the function in specific parts of organs (i.e. brain). The patient will be given a positron emitting substance most commonly fluorodeoxyglucose or FDG via intravenous injection. After which, the patient will go to the PET machine and the PET machine will measure the positron emitted throughout the body. Positron is well correlated to the function of a specific part of an organ.
The following is most likely true of a core sample of old, mature soil as D. It consists of several layers of different kinds of materials.
<h3>
What is mature soil?</h3>
Soil is bodily mature while it attains a moisture stage that permits it to interrupt into clumps measuring 1–10 mm. (With a better moisture content, the soil sticks to the tillage implement; with a decrease moisture content, the soil breaks into big clumps and clods.)
A soil can not be more mature than the oldest bushes developing in it. It can not be older than the substances wherein it paperwork or the panorama on which it's far found. Soil scientists paintings with geologists to decide how vintage the panorama is, and the way lengthy the figure substances had been there.

If he inherited a mutation that made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children is the circumstance that might his concern for his children be justified.
<h3>What do you mean by Mutation?</h3>
A Mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism.
Gametes of germline cells play an important role in the inheritance of mutation from parents to their offspring, which means that if a mutation has occurred in an egg or sperm cell, it will be more chances that the offspring carry mutated DNA.
Therefore, it is well-described above.
