Compare and contrast the function and structure of a compound light micrscope and electron micscrope

6 0

The major difference between a light microscope and a electron microscope would be that with the light microscope, a beam of light is used to focus the image. In an electron microscope, a beam of electrons is used to focus the image. Other notable differences would be with the light microscope, your specimens must be very thin; thin enough for light to pass through them. With the EM, you can place whole specimens that can generate 3D images. There is a much more complex specimen preparation process for the EM, where light microscope slide making is fairly simple in comparison. You can view live and wet specimens with a light microscope but you cannot with the EM because an EM requires specimens to be placed in a vacuum chamber. Lastly, the EM is very large and complex to operate, where the light microscope is somewhat portable. Hope this helps!

Answer:

The pic on the right is a solar eclipse and the one on the left is a lunar eclipse. Lunar eclipse only happens when the sun and moon are directly aligned in front of the sun. A lunar eclipse occurs when the Moon moves into the Earth's shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned with Earth between the other two, and only on the night of a full moon.

A stimulus is applied to the back of your hand, which results in the activation of two sensory neurons. the stimulus is applied

Leno4ka [110]

The recruitment of sensory neurons is known as population coding. Population coding is a method used to represent stimuli by applying the joint activities of a number of neurons. Each sensory neuron has a distribution of responses above some set of inputs, and the responses of many neurons may be added to ascertain some value about the inputs.

What is antigen?What does it include?What is its function?

Varvara68 [4.7K]

Antigens are proteins that are found on the surface of the pathogen and are viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles. Antigens are usually carried by proteins and polysaccharides, and less frequently, lipids but it also needs to be attached to a large carrier molecule which is usually a protein. When an antigen enters the body, the immune system produces antibodies against it. The Antigen stimulates the immune system to produce antibodies. YOUR WELCOME ;)
