Final Answer :
1. Gametes fuse in the gut of the female mosquito, Anopheles. The zygote will undergo divisions to produce sporozoites, which migrate to the salivary gland.
2. When a mosquito bites a person, the sporozoites are passed into the host's bloodstream, which migrate to the host's liver.
3. Asexual spores (merozoites) produced in the liver enter the host's bloodstream and enter the red blood cells.
4. Merozoites reproduce asexually inside the red blood cells.
5. Merozoites and toxins pour into the bloodstream, causing chills and fever.
6. Some merozoites become gametocytes, which enter the bloodstream. These are taken up by a new mosquito when she bites an infected person.
