Answer:a. prokaryotic. cellsExplanation:
Analogous structures have a different evolutionary ancestries but they have the same function
while homologous structures are the opposite; they have similar ancestries and common traits but maybe not have the same function in an organism
Jet streams are fast moving air currents much like how a river is a fast moving water current so the answer is jet streams.
When we perform a study, we test a specific hypothesis to see whether our hypothesis is supported by the data or not. If our hypothesis is not supported by the data, then we can argue that a specific argument (that would be important for this hypothesis) does not have a claim in scientific research.
This is more broadly meant though. Usually you need to perform multiple studies and test multiple hypothesis to be able to critique a scientific argument and see whether the claims it makes and the predictions it makes hold up in scientific research.
