Answer #1

Mutualism and symbiosis are positive interactions in which two or more species benefit, while Commensalism are positive interactions in which one species benefits and the other species neither benefit nor are harmed. Positive interactions are believed to be more common in unfavorable environments because these are areas where species may be struggling to persist.

  • Mutualism: In this relationship both partners benefit.
  • Commensalism: In this relationship only one species benefits while the other is neither helped nor harmed.
  • Parasitism: One organism (the parasite) gains, while the other (the host) suffers.

Northwestern Alaska is home to a variety of species. Some of these species and their interactions with one another are described here. Beavers (Castor canadensis, pictured on the left) eat willow shrubs; they also use willow as a source of material for building dams. Damming of waterways causes water to pool, which creates habitats that salmon use as spawning locations. Moose eat the same willow shrubs that beavers use to build their dams. The ptarmigan (pictured on the right) is...

Only one of the two species, Maleic acid and Fumaric acid, are predicted to be soluble in water. Which of the statements below correctly explains this? (If you feel that more than one statement is correct, choose all that apply). 1. Fumaric acid is soluble in water because to have solubility we need a polar and non-polar molecule to mix. 2. Fumaric acid is soluble in water because both water and Fumaric acid are non-polar, so their interactions are stronger....

Which of the following statements about descent with modification is false? A. Any two species share some characteristics because they descended from a common ancestor that lived at some point in the past. B. Over time, evolution by natural selection causes organisms to accumulate differences from their ancestors. C. All similarities between organisms result from descent from a common ancestor. D. Organisms that share a more recent common ancestor are likely to be more similar to one another than are...

The decision of two banks to form a network of compatible ATMs will make the services of these two banks closer substitutes, and likely lead to more aggressive competition between them in deposit rates. At the same time there will be a positive “network effect” because account holders of both banks have access to a larger ATM network. This trade off between the benefits of compatibility and the costs in terms of tougher competition is a common one in high-technology...

Scientists and conservationists are concerned that, due to new and growing threats, particularly associated with climate change, many species may soon be unable to persist in the habitats in which they currently occur. This has caused some to argue in favor of "assisted migration", whereby individuals of a species are moved from their native habitat into a new location that is highly suitable for them, but in which they had not previously been present. For example, the white lemuroid ringtail...
