Explanation:
Out of the options given in the question, the best one for this example is the Positron Emission Tomography (PET Scane) because it is stated that the active regions of the brain contain high concentration of glucose.
The reason is that a substance similar to glucose is used as an indicator in PET scans to show the part of the body where the inspection is required by emitting gamma rays.
I hope this answer helps.
Answer:
the meiosis is a process of cell division through which haploid cells are formed, it generally occurs during formation of gametes ( sex cells ) it is very important, because each parent contribute half number of chromosomes to the offspring, and that's the reason we have same number of chromosomes as our parents
( hence maintains the numbers of chromosomes in offspring )
This might have an evolutionary advantage as to why the egg behaves such. Presumably, this can help the yolk develop leaving it away from any inconvenient circumstance
