False. Complex parasite lifecycles do require vectors (biological or mechanical) for transmission.

True. Some vectors only carry the parasite without undergoing development within them.

False. Mechanical vectors only carry parasites, they don't develop inside them.

True. The life cycle of a parasite includes distinct stages, each representing a step in its development.

Parasites that live inside the body of their host.

The time period between initial infection with a parasite and when it can be detected (e.g., in a blood test).
