Question

protists are a group of organisms that are characterized as eukaryotes (they have cells with nuclei) that are neither plants nor animals nor fungi. they are very diverse, and there are many hypotheses about their classification. the cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. what is the implication of a changing hypothesis?

○ it is acceptable because data are still being collected.
○ it is acceptable because everything in science should always change.
○ it is not acceptable because the correct answer needs to be found.
○ it is not acceptable because science never changes.

Explanation:

In science, hypotheses change as new data is collected. For protists, ongoing research means more data is gathered, so changing hypotheses (like their cladogram) is acceptable as science is self - correcting with new evidence. The option "It is acceptable because everything in science should always change" is wrong as not everything changes arbitrarily. The options saying it's not acceptable are wrong because science does change with new data, and there's no fixed "correct answer" that can't be revised. So the correct reasoning is that changing hypotheses is acceptable due to ongoing data collection.

Answer:

A. It is acceptable because data are still being collected.
