Question

1. (01.01 mc) the body size of the individuals in a population of crabs starts decreasing. a geneticist believes that interbreeding with a smaller species may have happened. a marine biologist believes that the crabs may be undernourished. why are both of these options valid scientific hypotheses? (3 points) scientists with different educational backgrounds can come to different interpretations of the same data. no guess as to the answer to a scientific question can be considered a valid hypothesis since hypotheses are made before data collection. there is undocumented data to support both. both scientists underwent the same training and therefore must have the same validity in their work. 8. (01.02 hc) the graphs below show the change in temperature and salinity of a region of ocean as an instrument is lowered below the surface. depth is measured in kilometers below the surface, temperature in degrees celsius, and salinity in parts per thousand.

Explanation:

Scientists with different backgrounds (geneticist, marine biologist) can interpret the same data (about crab body size decrease) differently, leading to valid hypotheses. Other options are incorrect: hypotheses need data support, training doesn't ensure same validity, and hypotheses aren't just guesses.

Answer:

A. Scientists with different educational backgrounds can come to different interpretations of the same data.
