A marine scientist observes that fish are found at higher concentrations closer to the coast of California than farther out in t
he Pacific Ocean. She concludes the fish populations are always large close to the coasts throughout all oceans. Why is this an invalid scientific conclusion? a. She needs less data to draw conclusions.
b. Scientists should repeat this experiment at different sites to draw conclusions.
c. Scientists require laboratory-based experiments to draw conclusions.
d. Scientists always need long-term observations to draw conclusions.
When ever a scientific research or experiment is conducted , it is made sure that the results obtained are consistent through multiple trials. Here , only two trials are done i.e one on coast of California and the other on the Pacific Ocean.
Since the number of samples taken for this study are not as per the standard sample guidelines and hence the result obtained can not be considered as a acceptable.
The causes of the attractions and repulsion between molecules of water is that the oxygen and hydrogen atoms share electrons in bonds but its not equal. I hope this is the answer you are looking for! :)
I believe the correct answer would be B. Semipermeable means that it allows certain substances to pass through, and certain other ones to not pass through. So given all of your options, I would say that B makes the most sense. Hope this helped!
Earth can be divided into three MAIN layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. ... The inner core is solid, while the outer core is liquid.
