Concept explainers
To determine: The reason that the freshwater fishes are not osmoconformers.
Concept introduction: The fishes inhabit either in the fresh water or the marine water. The fresh water fishes are called as the“osmoregulators” and the marine fishes are called as the“osmoconformers”.
The osmoregulator mechanism helps the fresh water fishes to adapt the surrounding medium by the movement of salts and water across the gills of the fishes. This causes the body of the fishes to swell.
The osmoconformer mechanism in the marine fishes takes place by adapting their body to the changing conditions irrespective of the movement of salts and water.

- 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?
