Concept explainers
To answer:
According to the graphical representation, which epidemic disease affects many numbers of people during the first three days?
Concept introduction:
In an epidemic, a disease occurs at a greater frequency than the expected in a specific area or population. In the graph, the epidemic of two diseases is seen, which affect patients for only one day. Neither the blue disease nor the red disease is treatable and does not need any treatment. In the graph, both epidemics begin at the same time.
To answer:
What could explain the short time course for the red epidemic?

To answer:
Why was the blue epidemic longer lasting?

PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
