Aresearcher claimed that he had successfully cultured a type of bacteria that could generate heat from trash. however, no other researchers have been able to culture the same bacteria, even when they follow the same steps. so the claim made by this researcher violates which of the principles of scientific thinking?
(a)- replicability
(b)- empiricism
(c)- rationalism
(d)- skepticism

The correct answer is A) Replicability.

Explanation:

The principle of replicability states that the results obtained by a researcher, in certain investigation work, have to be the same for other researchers who are following the same steps. If the experiment cannot replicate under the same conditions, then it's not valid to the scientific community and therefore cannot be published.

d. organisms have cells with different shapes and functions.
