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.

The correct answer is Camouflage

The technique which is used by the animals to protect themselves from the predators. They prey usually changes the color of the body and match it to the surrounding environment so that the predators cannot recognize it.

The 4 types of processes that cycle matter through the biosphere include the carbon cycle, water cycle, nitrogen cycle, and phosphorous cycle.

• For example, nitrogen fixation and denitrification represent two fundamental processes by which nitrogen circulates between living and non-living components of the biosphere.

• Biological nitrogen fixation is a mechanism by which microorganisms are capable of converting nitrogen gas (N2) to ammonia (NH3).

• Denitrification refers to the bacterial process of reducing nitrate and nitrite to nitrous oxide and nitrogen, which are released as gases into the atmosphere.

In conclusion, the 4 types of processes that cycle matter through the biosphere include the carbon cycle, water cycle, nitrogen cycle, and phosphorous cycle.

Allele is not the name of a classification level because its not a part of taxonomical hierarchy. Therefore, option (A) is correct.

What is Taxonomic Hierarchy?

Taxonomic rank is the relative level of a group of organisms, known as a taxon, within an ancestral or hereditary hierarchy. This term is used in the field of biological categorization.

The Linnean system is the foundation for the modern method of classification, which consists of eight different levels of taxa. These levels, which are listed from most general to most specific, are as follows: domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.
