Answer:
Because they will increase or decrease in specific diseases which, along with other cell counts, would help narrow down the illness.
Explanation:
Lymphocytes one of the subtypes of immune cells present mainly in the lymph of the lymphatic system. They are composed of 3 types of cells
T-Cells
B-Cells
Natural-Killer (NK) Cells
T-Cells and B-Cells function as detection cells. Where they recognize & mark "non-self cells" or "infected self cells" as potential threat to the body and initiates or signals for their immediate elimination.
NK cells on the other hand, will recognize & eliminate "non-self cells" or "infected self cells" directly.
These cells will mostly respond to viral infections or tumor cells. Thus, their blood levels will increase mostly in these situations.
This means that if the patient is suffering from a fever or a sore throat, then the doctor can conclude whether this infection is caused by a viral or bacterial infection depending on how high Lymphocytes increases in the CBC test.
However, it should be noted that it is not used as a "sole" test but one of the tests to help narrow-down and pin-point the illness.
I hope that answered your question.
Answer:
Survival of the fittest; nature "selects" the organisms best suited to their environment to survive and pass on traits. ... What role does the environment play in natural selection?

<u>Population</u> is the term that defines groups of individuals that belong to the same species and live in the same area
Explanation:
In an ecological system, when a group of species of living organisms group and live in a particular locality area, it is referred to the population of that species.
Within an ecological boundary, there can be more than one type of population living in an area and all these different types of the population are interdependent with each other.
Within a population of a species, the individuals of the species interbreed, reproduce, grow and survive among themselves.
