Question

Scientists used trawling with nets to estimate the biomass of fish at different depths of the ocean. new evidence showed that some fish were able to avoid the nets, so the biomass estimates were inaccurate. when new evidence is discovered, what must scientists do next, and why?

Answer 1

To have an accurate result for this experiment, it is best for the scientist to be able to find or devise an appropriate methodology coupled with the most accurate tools or equipment. When data are properly gathered, it is easier for the scientist to interpret and give conclusion/recommendations. 

Answer 2

They must adjust the scientific ideas to account for all of the known evidence. This process makes scientific knowledge even more durable.
