List the six steps in the life cycle of Plasmodium vivax, the protist that causes malaria.

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.

4. Merozoites reproduce asexually inside the red blood cells.
