Answer:
d. PET is the correct answer.
Explanation:
PET stands for positron emission tomography it is a scanning test used to detect diseases in the body and it checks how the tissues and organs inside the body are functioning.
PET scans recognize the areas within the body that absorb sugar, so by PET scanning techniques measure the brain's glucose consumption as it is very effective tissue in the body that absorbs sugar.
A PET scan uses the radioactive drug to identify the difference in healthy and diseases tissue. The most common radioactive drug used is fluorodeoxyglucose.

Answer:
parasitism, commensalism
Explanation:
Parasitism is a form of interaction between two organisms in which the parasite lives on the host, obtain all its nutrients from the host and end up stifling the growth of the host. In summary, parasites reduce the fitness of their hosts by gradually killing them.
Commensalism is a form of interaction between two organisms in which the commensal benefits and the host is unaffected. The fitness of the host neither decrease nor increase.
Hence, when ticks (which feeds on the blood) reduced the fitness of white-footed mice in 2012, it is a parasitic relationship. When the blood feeding had no effects in 2013, it is a form of commensalism.
An analytical electron microscope is a transmission electron microscope geared up with analytical features inclusive of EDS (power dispersive X-ray spectrometry) and EELS (electron energy loss spectrometry), to enable qualitative and quantitative measurements, elemental distribution mapping, and chemical kingdom analyses in ...
The transmission electron microscope is used to view skinny specimens (tissue sections, molecules, and so on) via which electrons can bypass generating a projection photograph. The TEM is analogous in lots of methods to the traditional (compound) light microscope.
TEM may be used to take a look at the increase of layers, their composition, and defects in semiconductors. the excessive decision can be used to analyze the exceptional, shape, length, and density of quantum wells, wires, and dots. The TEM operates on identical basic principles because the light microscope makes use of electrons in preference to mild.
