Microscopes

I and II. Compound and dissecting microscopes can be used to view living samples due to their lower magnification and non-destructive imaging techniques. III and IV. Scanning and transmission electron microscopes are not ideal for viewing living samples as they typically require a vacuum environment and can damage the specimens.

One example of a living creature that is too small to be seen without a microscope is a bacterium. Bacteria are single-celled microorganisms that are typically a few micrometers in size and can only be seen with the aid of a microscope.

The tissue most likely being viewed is skeletal muscle tissue. Skeletal muscle tissue is composed of long and thin fibers called muscle fibers that exhibit striations due to the arrangement of contractile proteins. These muscle fibers contain multiple nuclei and mitochondria to support their high energy demands.

Onion epidermis is a suitable tissue for observing cellular structures with a compound light microscope because it is transparent, allowing light to pass through easily, and the cells are thin enough to view individual cells and structures such as cell walls, nuclei, and chloroplasts. Additionally, the large size of onion cells compared to other plant cells makes it easier to study their internal structures.

Arteries and arterioles are not visible to the naked eye, as they are too small. They require a microscope or other imaging techniques to be seen.

Compound microscopes are popular due to their ability to magnify images at high levels, providing detailed views of small objects. They also offer versatility by allowing users to view transparent and translucent specimens. Additionally, compound microscopes are available in various models, making them suitable for different applications in various fields.

To examine a prepared slide using a microscope, first place the slide on the stage and secure it with the stage clips. Start with the lowest magnification objective lens, adjust the focus using the coarse adjustment knob, then fine-tune the focus with the fine adjustment knob. Once the image is in focus, you can adjust the magnification by rotating the nosepiece to switch to a higher magnification lens for detailed observation.

First you have to put gloves on to protect your skin. Next you dig yourself a nice deep hole in the ground and you burry yourself in it and you have your grave. Then you scream help as loud as you can to see if somebody helps and if someone comes and asks do you need help say no go away I'm dying in a hole.

Bacteria are too small to see without a microscope. WAY too small.

The objective lens is the part of a microscope that typically magnifies about 40x. By combining with other lenses in the system, such as the eyepiece, the overall magnification of the microscope can be further increased.

well, "MICRO" means "small" and "SCOP" (yes, with out the "e") is a greek root word meaning "see"

low power objective lens to locate and focus on the specimen before moving to higher magnifications.

Individual cells are not visible under an electron microscope because the resolution of the microscope is not high enough to distinguish the borders of individual cells. The electron microscope's resolution is limited by the wavelength of electrons used, preventing the visualization of single cells. Cells can be seen collectively as tissues or structures under an electron microscope.

Microscopes have contributed significantly to society by enabling scientists and researchers to study and understand the intricate details of cells, microorganisms, and materials at a microscopic level. This has led to breakthroughs in medicine, biology, materials science, and other fields, ultimately improving our quality of life through advancements in healthcare, technology, and scientific knowledge.

A specimen is in focus when you can clearly see and distinguish its details when looking through a microscope. Adjusting the focus of the microscope allows you to bring the specimen into clearer view.

A cover slip is placed over a sample on a microscope slide to protect the sample from dust and damage, to prevent evaporation of any liquids present, and to create a flat surface for the objectives to focus on. This also helps to improve the clarity and quality of the image seen through the microscope.

When viewing the letter "e" through a microscope, you would see a magnified image of its structure, revealing details such as the texture and any imperfections. The magnification would allow you to observe the fine lines and curves that make up the letter.

In most classrooms today, a compound microscope typically has two lenses located within the eyepiece and the objective. The eyepiece lens (or ocular lens) is located at the top of the microscope and is used to view the magnified image of the specimen. The objective lens is located near the specimen and is responsible for magnifying the image of the specimen before it reaches the eyepiece.

The resolution of a microscope is a key factor in determining how well it can show small details. Resolution is the ability of a microscope to distinguish between two separate points in an image. Other factors that can affect the quality of the image produced by a microscope include magnification, lens quality, and lighting.

Under a low power microscope, you can see larger structures such as plant cells, blood cells, small insects, and other objects that are not visible to the naked eye, but lack fine details that would be visible with higher magnification.

When viewed under the microscope, an image appears magnified compared to how it looks on the stage. The microscope allows you to see fine details and structures that are not visible to the naked eye. Additionally, the image may appear clearer and more defined when viewed through the microscope's lenses.

The scanning tunneling microscope (STM) is typically used for imaging surfaces of materials at the atomic level, regardless of whether the sample is alive or dead. The STM works by scanning a sharp metal tip over the sample surface and detecting the tunneling current between the tip and the surface, allowing for atomic-scale resolution imaging. It is commonly used in both materials science and nanotechnology research.

The term "compound" refers to the microscope's use of multiple lenses in its optical system. A compound light microscope uses two sets of lenses to magnify the image: the objective lens near the specimen and the eyepiece lens near the observer's eye. This design allows for greater magnification and clearer imaging than a simple light microscope.

The illumination system in a light microscope provides light to illuminate the specimen being viewed. It helps to enhance contrast, improve image clarity, and enable visualization of the specimen's details. Adjusting the intensity and angle of the light can optimize the quality of the image.

The total magnification would be 100x. This is because when two lenses are used together, the magnification of each lens is multiplied to find the total magnification. So, 10x magnification from the first lens multiplied by 10x magnification from the second lens gives a total magnification of 100x.
