B.
Warm air rises and takes heat with it; eventually it cools and sinks.
Explanation:
Answer:
The correct answer will be- Transmission electron microscope
Explanation:
A Microscope is an optical instrument designed to view the microscopic things which could be living or non-living around us.
The internal structure of a microscope can be viewed by a light microscope mainly dark-field microscope but a detailed structure of a microscope can be viewed by an electron microscope mainly a transmission electron microscope.
The transmission electron microscope studies the internals structure of the cell by creating the 2D images by passing the beam of electrons through the specimen.
Thus, a transmission electron microscope is the correct answer.
