We have that "J.J. Thomson proposes a new model of the atom" statement refers to the Plum Pudding model by the scientist J.J. Thomson.
From the question we are told
Thomson proposes a new model of the atom?
Generally
- J.J. Thomson was a scientist that dedicated his lives work to studding atoms and its particles
- J.J. Thomson is most famous for his evolutionary work with the cathode ray tube
- The Cathode ray tube gave rise to the discovery of the electrons at that time was called little negatively charged particles within the atom
- This caused J J Thompson to propose a law which stated that atoms where particles which were made up of negative charge around Positive charges
- This was called Plum Pudding
Therefore
"J.J. Thomson proposes a new model of the atom" statement refers to the
Plum Pudding model by the scientist J.J. Thomson.

Answer:
Stephen is not his biological father.
Explanation:
DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.
The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.
Thus, the correct answer is option (a).
<u>ANSWER:</u>
"Publish experiment results only if they agree with current theories or public opinion" is an example of society which expects to follow ethical practices and meet many ethical standards. .
<u>EXPLANATION:</u>
- It is important for researchers to ensure that they conduct experiments on the basis of true and desirable data so that the results of the experiment can be accurate.
- Research ethics also require that experiments be undertaken only under favorable conditions and not under all circumstances.
- Sometimes, it is required not to conduct experiments and therefore researchers must refrain from the same.
- It is also essential as per research ethics for researchers to analyse data correctly and investigate all events and not only events that impact the lives and livelihood of people.
- Researchers need to conduct their experiments without any bias.
