- Below are statements about symbiosis. Choose the correct responses. ( Only pick one answer per [ ] ) ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when two organisms both benefit from a relationship. One example of this you will view is lab is ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"] . ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when one organism benefits, while the second organism is not harmed, and does not benefit. ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when one organism benefits while the second organism is harmed. In lab you will explore ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"] as an example of this relationship.arrow_forwardDescribe parasitologyarrow_forwardReveal the weakest link in the chain of infectionarrow_forward
- Is the species-specificity rule of parasitism ever broken?arrow_forwardParasites can move between hosts either by horizontal or vertical transmission. Why might those parasites that employ horizontal transmission be more impacted by environmental stochasticity? Host defenses may be impacted by environmental conditions. Pathogenicity may be impacted by environmental conditions. Vectors may be affected by environmental conditions. Vertical transmission requires a vector.arrow_forwardWhich one of the following terms is NOT directly relevant to the ecology of infectious disease? Select one: pathogen structure latent period geographical range pathogen distribution generation periodarrow_forward
- In your own words and in 2 paragraphs: Explain how metamorphosis influences parasitism?arrow_forwardThe rate and magnitude of the spread of infectious organisms through populations depends on its mode of transmission and on the infectious agent’s growth characteristics.Describe the portals of entry that pathogenic organisms need to bypass to cause diseases.arrow_forwardMatch the periods of disease with their characteristics: incubation period prodomal period period of illness period of decline period of convalenscence Word bank - pathogen begins to decline in number and symptoms begin to abate - signs and symptoms of illness are obvious and severe - initial signs and symptoms of illness begin to present - host recovers and returns to a general state of health - pathogen begins to establish itself in the host, but no signs or symptoms are presentarrow_forward
