Answer: History
Explanation: The history effect is an experimental research problem,which stems from the likelihood that an observed effect or result in our experiments is as a result of an extraneous affect or factor rather than the applied treatment used in the experiment.
In the scenario above, the group were being taught alphabet as treatment at about the same time when alphabet was being taught on television. Therefore, the result of the experiment may be influenced by the Television program rather than the applied treatment.
The challenges of molecular biology in clinical practice include:
- lack of funds to support clinical application of molecular biology
- ethical issues regarding the application of molecular biology in clinical practice
<h3>What is molecular biology?</h3>
Molecular biology is the study of biological molecules at the molecular level.
Molecular biology involves the study of such molecules as DNA and RNA and how the affect the production of macromolecules such as carbohydrates, proteins and lipids.
The challenges of molecular biology in clinical practice in recent times include:
- lack of funds to support clinical application of molecular biology
- ethical issues regarding the application of molecular biology in clinical practice
In conclusion, molecular biology is biology at the molecular level.
