One limitation of the scanning electron microscope is that it cannot be used to?
One limitation of the scanning electron microscope is that it cannot be used to observe live samples or biological materials in their natural state. The high vacuum environment and the electron beam can damage or alter the sample.
What instruments was necessary before the cell theory could be developed?
Before the cell theory could be developed, the invention of the microscope in the 17th century was necessary. This allowed scientists like Robert Hooke and Anton van Leeuwenhoek to observe and describe various cellular structures. Additionally, advancements in staining techniques were needed to visualize cells more clearly.
What problems did scientists have before the invention of the microscope?
Before the invention of the microscope, nobody knew that the microscopic world existed. As a result nobody knew what they were missing out on, and so there were no known difficulties to not having microscopes.
Which would NOT be an appropriate procedure for the observation of a living paramecium under a compound light microscope?
Using a high magnification objective lens without properly adjusting the focus first would not be an appropriate procedure for observing a living paramecium under a compound light microscope. This could result in damaging the paramecium or causing it to move out of view before being able to observe it accurately.
What is a Specimen Smaller Than 0.2 Micrometers Must Be Completely Dried Out Before Being Studied Using This Type Of Microscope?
Electron Microscope
Why do you think little was known about cells before the invention of the microscope?
Before the invention of the microscope, cells were too small to be seen with the naked eye. Without the ability to magnify and observe cells at a microscopic level, scientists had limited tools to study them, leading to little knowledge about their structure and function. The microscope revolutionized biology by allowing scientists to observe and understand the building blocks of life at a cellular level.
One limitation of the scanning electron microscope is that it cannot be used to?
One limitation of the scanning electron microscope is that it cannot be used to observe live samples or biological materials in their natural state. The high vacuum environment and the electron beam can damage or alter the sample.
What invention was necessary before cell could be discovered?
The invention of the microscope was necessary before the cell could be discovered. The microscope enabled scientists to observe and study cells at a microscopic level, leading to the identification of cells as the basic unit of life.
What instruments was necessary before the cell theory could be developed?
Before the cell theory could be developed, the invention of the microscope in the 17th century was necessary. This allowed scientists like Robert Hooke and Anton van Leeuwenhoek to observe and describe various cellular structures.

No, you are not required to wash a rental car before returning it to Hertz.
How many stops did a triangular trade rout make before returning home?
Two stops before returning home.
Why did people not know about cells before the invention of the microscope?
Cells are microscopic structures invisible to the naked eye, so prior to the invention of the microscope, people did not have the technology to observe and study them. Therefore, without the ability to see cells up close, their existence and structure remained unknown.
Three things that you should do to prepare for a lab?
A lab should be fully prepared before an experiment is performed. Three things that should be in a lab are, paper and pencils, beakers, and a microscope.
