Compare and contrast horizontal versus vertical transmission of a
A parasite is an organism that lives on another organism (host) and obtains all nutrients needed for survival from the host. In turn, the host is affected by the parasite. Parasites can also be transmitted from one host to another.
Transmission of parasites from one organism to the other can happen in one of two modes, horizontal or vertical.
Step by step
Solved in 2 steps
- provide example of a parasite that develop a life cycle involving an intermediate hosts? explainName a parasite in the environment in which it has positively impacted another organism or its ecosystem. Discuss in detail the positive impact of this parasite.Why would a parasite develop a life cycle involving an intermediate hosts? What is this giving the parasite? Provide example(s)
- Symbiotic relationships include both mutalism and parasitism. Give an example of a symbiotic relationship between two organisms.Describe how different mechanisms of interaction among parasites within a host (i.e. exploitation, interference, or apparent competition, and/or public goods cooperation) are expected to affect how virulence evolves.Choose an example of a host adaptation that may not look advantageous at first, but was determined to reduce parasite load. Explain the mechanism for why this came to be and why it was advantageous.
