Answer: Radioactively-labeled materials

Explanation: nuclear medicine is a medical specialty that uses radioactive tracers to diagnose and treat different diseases. Radioactive tracers are materials that can vary according to the purpose of the method. For most diagnostic, the radioactive tracer is administered by intravenous injection. However it may also be administered by inhalation, by oral ingestion, or by direct injection into an organ.

SPECT scans are primarily used to diagnose and track the progression of heart disease, and the major purpose of PET scans is to detect cancer and monitor its progression, response to treatment, and to detect metastases. This two methods are the most used in nuclear medicine.

Stolb23 [73]

Answer:

The correct answer is option A.

Explanation:

Nominal GDP is the measure of economic growth which calculates the change in output on the basis of the current price. It is not inflation-adjusted measure and is affected by changes in the price level.  

Real GDP on the other hand, measures the change in economic output on the basis of constant price. It is an inflation-adjusted measure to calculate economic growth.  

That is why, real GDP is preferred, because nominal GDP may overestimate or underestimate the change in output.

Color blindness is a sex-linked recessive disorder on the X chromosome. If the allele “b” is used to denote color blindness, rec
yuradex [85]

Answer:

If the "b" allele denotes color blindness, a color blind woman would have the "bb" genotype.

Explanation:

Although color blindness is a genetic condition linked to the X chromosome, it is very rare for color blind women to exist, although they may carry the allele that denotes color blindness.

This is because women have two X chromosomes, if a woman receives an X chromosome from her father containing the "b" allele (which represents color blindness), but receives an X chromosome from her mother which contains the "B" allele (which does not represent color blindness), this woman will not be color blind, although she may pass the defective gene on to her children.

With this, we can affirm that, in women, color blindness is only expressed in recessive homozygosity, for this reason, a color blind woman would have the "bb" genotype.
