Hence, option A is correct
vacuoles
cytoplasm
mitochondrion
Cellular respiration has been defined as the process of gaining energy by the cell with the use of Oxygen.
Thus, the site for cellularrespiration in the cell has been mitochondria. Thus, option D is correct.

The answer would be the Mitochondrion! You may have heard it before, as it is the power house of the cell. This is where cellular respiration and energy production take place.

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.
Answer:
The emergence of the new species of the organisms may take place if the naturally occurring selective pressure encourages the emergence of new traits. The pressure from the surroundings like sudden variation in the climate or temperature or any other thing that develops a pressure on the species to modify phenotypically and genotypically.
This change will result in the evolution of the species and with the time being the emergence of new species of organisms takes place.
naturally occurring selective pressures favor new traits.
humans create new environmental conditions.

(2) digestion (4) decomposition
