Question

The graph below shows the percent of eggs from two fish species that hatch when grown in water with different salinity. Response of Eggs to Saltwater Eggs That Hatched (%) Salinity of Water (mg Na/L H2O) Which of the following best summarizes the effect of the saltwater on these species of fish eggs? Responses A Only Species 2 can hatch with a low salt concentration, and Species 2 is not affected by the salinity.Only Species 2 can hatch with a low salt concentration, and Species 2 is not affected by the salinity. B Both species require saltwater to hatch.Both species require saltwater to hatch. C Both species of fish can hatch in saltwater, but Species 1 can hatch in a higher salt concentration.Both species of fish can hatch in saltwater, but Species 1 can hatch in a higher salt concentration. D Species 1 can only hatch in saltwater, and Species 2 can only hatch in freshwater.

Answer 1

To summarize the effect of the saltwater on the two species of fish eggs based on the provided options and the typical responses to salinity, the best choice among the given options would be:

A: Only Species 2 can hatch with a low salt concentration, and Species 2 is not affected by the salinity.

This option best reflects a situation where at least one species (Species 1) has a higher salt concentration requirement for hatching, while Species 2 is able to hatch at low salt concentrations and remains unaffected by varying levels of salinity.

If your graph supports any other specific characteristics regarding the salinity tolerance for each species, please provide that data for a more accurate assessment.
