Research Methodology Quiz 2

What are radioisotopes?

• Unstable isotopes

• Stable isotopes

• Protons

• Neutrons

Answer explanation

Radioisotopes are unstable isotopes that decay over time, emitting radiation. This instability distinguishes them from stable isotopes, making 'unstable isotopes' the correct choice.

Identify the radioactive element used to study photosynthesis in plants?

  

• Iodine

• Potassium

• Carbon

• Bromide

Answer explanation

Carbon, specifically in the form of carbon-14, is used in studies of photosynthesis to trace the incorporation of carbon dioxide into organic compounds in plants, making it the correct choice.

Identify the radioactive element used to diagnose goiter.

    

• Iron

• Iodine

• Calcium

• Thyroxine

Answer explanation

Iodine is a radioactive element essential for thyroid function. It is used in medical imaging to diagnose goiter, a condition caused by iodine deficiency affecting thyroid hormone production.

Which component is present in Scintillation counter that helps to emit visible photons?

 

• PMT

• Scintillator

• Fluor crystal

• Metal sheet

Answer explanation

The correct answer is 'Fluor crystal' because it is the component in a scintillation counter that absorbs high-energy radiation and re-emits it as visible photons, enabling detection.

Liquid Scintillators are used for which of the following materials?

• alpha

• beta 

• gamma

• delta

Answer explanation

Liquid scintillators are effective for detecting gamma radiation due to their ability to produce light when gamma photons interact with the material. They are less effective for alpha and beta particles.

A review of the literature prior to formulating research questions allows the researcher to:

• Provide an up-to-date understanding of the subject, its significance, and structure

• Guide the development of research questions

• Present the kinds of research methodologies used in previous studies

• All of the above

Answer explanation

A review of the literature helps researchers understand the subject, its significance, and methodologies used, which collectively guide the development of research questions. Thus, 'All of the above' is the correct choice.

Assertion: It is good to keep a research diary while conducting the research.

    Reason: It will keep a record of what has happened throughout the research process.

   

• (A) is correct and (R) is correct explanation of (A)

• (A) is wrong and (R) is correct

• (A) and (R) are wrong

• (A) is correct but (R) is wrong

Answer explanation

The assertion (A) is correct as keeping a research diary is beneficial. The reason (R) accurately explains (A) by stating it helps maintain a record of the research process, thus supporting the assertion.

Assertion: Citation is mandatory in a research article.

    Reason: In a research report it is essential to acknowledge all sources from where the

                    information was obtained.

 

• (A) is correct but (R) is wrong

• (A) and (R) are wrong

• (A) is wrong and (R) is correct

• (A) is correct and (R) is correct explanation of (A)

Answer explanation

The assertion (A) is correct because citation is indeed mandatory in research articles. The reason (R) correctly explains (A) by emphasizing the importance of acknowledging all sources of information used in the research.

Which is the ideal font size and font type used while typing a thesis?

     

• Font size 12 and Font type Times New Roman

• Font size 11 and Font type Book Antiqua

• Font size 13 and Font type Arial

• Font size 14 and Font type Times New Roman

Answer explanation

The ideal font size for a thesis is 12, and Times New Roman is the standard font type used in academic writing. This combination ensures readability and meets most academic guidelines.

Is it necessary to follow the formatting rules while preparing a research report?

• True

• False

Answer explanation

True. Following formatting rules in a research report ensures clarity, consistency, and professionalism, making it easier for readers to understand and evaluate the work.
