The doctor who is concerned that wilma may have a brain tumor recommends that a(n) positron emission tomography (PET) scan.
PET scan is a scan imaging test that allow doctor to check disease in human body. This scan uses a special dye that contain a radio active tracer.This scan provide information about blood flow and how body is using oxygen and sugar.
For #1, the last choice is correct. A geocentric model means that the earth is the center of the universe while all other bodies orbit around it. A heliocentric model means that the sun is the center of the inverse while the other bodies orbit around it. The shared feature is that the other bodies in space move in circular orbits.
For #2, the first answer is correct. When the moon is between the earth and the sun, positions X and Z are being pulled by the moon’s gravitational force, creating high tides at these places. However, positions W and Y are experiencing low tides because no gravitational pull is making them high.
Answer:
Option B, It allows different kinds of organisms to be easily identified based on their characteristics
Explanation:
Options for the question are
- It provides a detailed evolutionary history of all the known organisms on Earth
- It allows different kinds of organisms to be easily identified based on their characteristics
-
It allows scientists to group organisms based on their personal preference
- It prevents people who are not scientists from studying and identifying organisms.

Solution
A standardized taxonomic system provides a common basis for the entire scientist community to identify and classify organism on common grounds and hence leading to a standardized organism classification across the globe.
This also groups organisms into different kingdoms, taxas and classes with defined hierarchy and description of shared traits and characteristics. It also provides scope for inclusion of newly discovered species thereby making the standardized taxonomic system flexible
Hence, option B is correct
