1. A scientist cut an amoeba into two halves and found that only the part with the nucleus survived.
He then concluded that the nucleus is necessary for the survival of cells.
valid?
No.
Is this conclusion
Explain.
The conclusion is over-generalised.
It cannot be applied to all the other cells which
have not been studied. The validity of the conclusion will increase if a large number of cells
of different types are studied with the same conclusion being drawn.
2. Do you think scientific knowledge on the nucleus that you have learned from your textbooks
will change in the future? Explain.
Yes.
Background scientific knowledge will change when we know more from additional
experiments / investigations / observations / information.
New evidence, new technology, or
viewing the same data in a different way from before may also bring about new insights.
3. Sometimes scientists describe their work to other people in the following way, “I am doing
research.”
Why is scientific work called “research”?
Scientific investigations often raise further questions that lead to better understanding of nature.
The search for answers to endless questions is an ongoing process that gives academic work its
name “Re-Search” = searching again for confirmation or different outcomes.
