Question

1. (01.01 mc) a marine scientist is studying photosynthetic organisms, which use sunlight to produce their own food. she observes that they tend to populate shallower ocean depths. she concludes that photosynthetic organisms can only live in areas of low pressure. why is this an invalid scientific conclusion? (3 points) the data she collected was not in a laboratory. other variables were not accounted for. the data was collected in natural conditions and cannot be used. the data was not numerical and cannot be graphed.

Explanation:

A valid scientific conclusion requires accounting for all variables. The marine scientist's conclusion is invalid because other factors (like temperature, salinity, etc.) affecting the organisms' habitat were not considered. Other options: Lab vs natural data isn't the issue here, natural - collected data can be valid, and data about depth can be numerical/graphed.

Answer:

Other variables were not accounted for.
