Well, all of the kingdoms existed, they just hadn't been discovered yet. However, the ones that had been discovered were plant and animal.
Bacteria and protists are microscopic, so without a microscope you cannot see them, and fungi were thought to be plants. Scientists didn't have the technology (the microscope) to be able to see the differences in the functions and structures of the fungi kingdom and the plant kingdom.

Why must specimens viewed with a compound microscop be thin?
Specimens viewed with a compound microscope must be thin to allow light to pass through them. This ensures that the light rays can illuminate and pass through the specimen, which is necessary for magnifying the image and producing a clear view under the microscope. Thicker specimens would scatter or block the light, resulting in a blurry or dark image.
Why must the underside of the microscope slide be dry before being placed on a microscope?
Having the underside of the microscope slide dry prevents water droplets from interfering with the light passing through the slide, which could result in distorted or unclear images when viewed under the microscope. Additionally, a dry slide ensures that the specimen is in direct contact with the glass surface, facilitating better observation and imaging.
Why can't we use human cells to look at under a microscope?
We can use human cells to look at under a microscope; in fact, it is a common practice in biological research. However, human cells typically require special preparation, such as fixation or staining, to enhance visibility under a microscope. Additionally, the cells must be cultured properly, and sometimes they are viewed in thin sections to allow for adequate light penetration. Overall, while human cells can be observed microscopically, they need specific techniques to ensure clarity and detail.
When using a light microscope to view a cell you obtaied from scraping under your fingernails you notice that the cell lacks a nucleus therefore you conclude that the cell must be a type of what cell?
Prokaryote
What is a Specimen Smaller Than 0.2 Micrometers Must Be Completely Dried Out Before Being Studied Using This Type Of Microscope?
Electron Microscope
How must samples be prepared by observation by an electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.

Why must a specimen be thin in order to be viewed under the microscope?
Specimens must be thin in order to be viewed under the microscope because light can only pass through a certain thickness of material. A thin specimen allows light to pass through and interact with the cells, allowing the microscope to produce a magnified image. Thicker specimens would prevent light from passing through and produce a blurry or unreadable image.
Why must specimens viewed with a compound microscop be thin?

Thicker specimens would scatter or block the light, resulting in a blurry or dark image.
Why must specimens viewed with a compound microscope be thin why are they sometimes stained with dyes?
Specimens viewed with a compound microscope need to be thin to allow light to pass through and be focused by the lenses. Staining with dyes increases contrast and visibility of certain structures within the specimen by highlighting specific parts of the sample. This helps to distinguish different components and makes them easier to observe under the microscope.
Why must a specimen be thin to be viewed under the microscope and why are they sometimes stained with dyes?
Specimens need to be thin to allow light to pass through and enable clear visualization under the microscope. Staining with dyes helps to highlight specific structures or components within the specimen, making them easier to observe and distinguish.
How must samples be prepared for observation by an electron microscope?
Samples for observation by an electron microscope are typically prepared by fixing the specimen in a chemical solution, dehydrating it, and then embedding it in a resin for stability. The sample is then sliced into ultrathin sections using a microtome before being stained to enhance contrast. Finally, the prepared sample is placed inside the electron microscope for imaging.
Why should a specimen to be viewed under the microscope must be thin?
Body tissues and bones are opaque beyond a certain thickness. To view fine structures, exceedingly thin samples will be translucent, revealing cell and tissue structure.
Why a specimen need to be viewed under the microscope must be thin?
Specimens need to be thin to allow light to pass through them and be able to observe details and structures at a cellular or subcellular level. Thicker specimens would block the light and hinder the ability to visualize the specimen clearly under a microscope. A thin specimen also helps to reduce scattering and distortion of the image.
Is AIDS an organism that can be seen under a microscope?
AIDS is the disease caused by the virus called HIV. It can not be seen under a light microscope (as one in the class lab) but you must use an electron microscope as they are very tiny.
Why must the underside of the microscope slide be dry before being placed on a microscope?
Having the underside of the microscope slide dry prevents water droplets from interfering with the light passing through the slide, which could result in distorted or unclear images when viewed under the microscope. Additionally, a dry slide ensures that the specimen is in direct contact with the glass surface, facilitating better observation and imaging.
What can be viewed with a light microscope?
Anything that is smaller than the wavelength of light, thatmeans that it is smaller than light and therefore is not visible, at all, to know it exists an electron microscope must be used which captures a reflection of the object a scanning electron microscope uses a computer to make the image
