Question:
(a) Why do the symptoms of malaria not appear in a person immediately after being bitten by an infected female Anopheles? Give one reason. Explain when and how do the symptoms of the disease would appear.
(a) Why do the symptoms of malaria not appear in a person immediately after being bitten by an infected female Anopheles? Give one reason. Explain when and how do the symptoms of the disease would appear.
Show Hint
The incubation period of malaria allows the parasite to multiply in liver cells before invading red blood cells, causing symptoms.

Solution and Explanation
- The sporozoites take time to multiply in the liver cells before infecting red blood cells, which delays the onset of symptoms.
- Symptoms like fever, chills, and sweating appear when the parasite ruptures red blood cells and releases toxins into the bloodstream.
