Question

use the drop - down menus to match each phrase below with the type of microscope it describes. creates a two dimensional image is used to study dna molecules has magnification ability of up to 60,000 times without shows arrangement of atoms on surface of molecules has magnification ability of hundreds of thousands of times transmission electron microscope (tem) scanning electron microscope (sem) scanning tunneling microscope (stm)

Explanation:

Match each microscope to its key characteristics based on standard biological/ microscopy knowledge:

1. Transmission Electron Microscope (TEM) produces flat, 2D images and has very high magnification (hundreds of thousands of times), suitable for internal structures and large molecules like DNA.
2. Scanning Electron Microscope (SEM) has a maximum magnification around 60,000x and creates detailed surface views (but not atomic-level).
3. Scanning Tunneling Microscope (STM) can visualize the arrangement of individual atoms on a molecule's surface.

Answer:

• transmission electron microscope (TEM): creates a two dimensional image; is used to study DNA molecules; has magnification ability of hundreds of thousands of times
• scanning electron microscope (SEM): has magnification ability of up to 60,000 times without
• scanning tunneling microscope (STM): shows arrangement of atoms on surface of molecules
