Scientific Tools in Advanced Research

Read each question carefully and provide the best answer based on your knowledge of scientific tools and their applications in advanced research. Some questions may require critical thinking and application of concepts.

1. Which of the following analytical techniques is best suited for determining the elemental composition and isotopic ratios of a sample?

2. A researcher needs to visualize the 3D structure of a protein at atomic resolution. Which advanced imaging technique would be most appropriate?

3. A   is commonly used to separate biological macromolecules based on their size, charge, or binding affinity.

4. The technique of   involves using a powerful magnetic field to probe the structure of molecules based on the magnetic properties of their atomic nuclei.

5. Explain the primary difference in application between a scanning electron microscope (SEM) and a transmission electron microscope (TEM).

6. Describe the principle behind X-ray diffraction (XRD) and its significance in materials science.

7. A spectrophotometer measures the absorbance or transmittance of light through a sample, which can be used to determine the concentration of a substance.

8. Gel electrophoresis separates molecules based solely on their mass, regardless of their charge or shape.

Match each scientific tool with its primary function.
