Answer: C. A researcher may claim that one variable causes another to occur if test results are significant.
Explanation:
Correlation analysis is not meant to show causation between variables but merely to find out if there is a relationship.
While there is a chance of one variable causing another if they are correlated, it is not always the case as there might be another unforeseen variable.
Even if results are significant, a researcher should never claim that one variable can cause another from correlation analysis.
Answer:
The correct answer is D.
Explanation:
Bordetella pertussis is a gram-negative coccobacillus that causes a disease called whooping cough.
The bacterium infests the patients by colonizing lung epithelial cells. To do so, it requires adhesins, called filamentous haemagglutinin, fimbriae and pertactin. Once the bacterium is attached to the lung epithelial cells, it produces a cytotoxin that prevents their cilia from moving.
Another virulent factor from B. pertussis is the pertussis toxin, which alters host immune system through the inhibition of phagocytes response to it.

Answer:
Pallor
Fatigue
Easy bruising
Cyanosis
When symptoms begin, a child appears pale, fatigues easily, and has anorexia from the lowered RBC count and tissue hypoxia. Because of reduced platelet formation (thrombocytopenia), the child bruises easily or develops petechiae (pinpoint, macular, purplish-red spots caused by intradermal or submucous hemorrhage). A child may have excessive nosebleeds or gastrointestinal bleeding. As a result of a decrease in WBCs (neutropenia) a child may contract an increased number of infections and respond poorly to antibiotic therapy. Observe closely for signs of cardiac decompensation such as tachycardia (not bradycardia), tachypnea (not bradypnea), shortness of breath, or cyanosis from the long-term increased workload of all these effects on the heart.
