On a microscope What is beneath the stage and directs light onto the slide?
The light in a room is captured on some models of microscopes by a mirror. The light passes through the stage opening and illuminates the specimen on the slide. The light is then focused by an array of lenses before exiting the eyepiece. Some models of microscopes use a light called an in base illuminator in place of a mirror that shines a bright toward the microscope's stage opening.
Which invention allowed us to discover cells?
Robert Hooke is credited for discovering and naming the cells found in both living and dead organisms. Using the bark of a cork tree, he was the first to see cells under a microscope.
Are you observing an organism through the microscope and noticed that it moved toward the bottom of the slide and then it moved to the right. what does this tell you about the actual movement?
It is actually opposite meaning that it moved up and to the left.
What is the working principle of electron microscope?
An electron microscope is a magnifier that uses electrons to enlighten the subject and display a magnified image. The electron microscope has a greater amount of resolution as compared to other microscopes. Using this, smaller objects can be seen with a naked eye as they have lesser wavelength than light, hence it has a very strong resolving power to view the object in a larger picture. In this article, we would be taking a look at how does an electron microscope work? Before answering how does the electron microscope work, you must know that there are mainly two types of microscopes. One is a Transmission Electron Microscope (TEM), and the other is the Scanning Electron Microscope (SEM). Let us first understand how an electron microscope works? The TEM was the first ever electron microscope and it was used to see within the cells. The TEM allows only those electrons to be viewed which pass through the subject, which obviously means that only those electrons which pass through the sample may be seen. This gives rise to black/white and shades of gray on the finished picture. The electron is a pin-shaped cathode, heated to an extent which induces a beam of electrons to be developed. The empty space that resides within the microscope then makes the electron ray to move into the condenser. The condenser is an electromagnet that concentrates on the electron rays onto the object. Then the electrons are averted off when they hit the areas of the object. This is due to the object being smeared with weighty metals, which will be imbibed by particular portions of the cell that will then bend the electrons in a different manner and allow the quite visible contrasts within the cell. The Projective which is nothing but a series of lens-arrangements, then focuses the leading electron beam onto a fluorescent shield where a black and white picture is generated. It is used when only the surface of the object is to be viewed as in this case the image is generated from the reflected electrons.
The leaves of plants always grow toward sunlighthow does this behavioral adaptation help keep the plant alive?
the organism act in response to their environment
What function of course focusing mechanism?
The coarse focusing mechanism is the rough focus knob on the microscope. It is used to move the objective lenses toward or away from the specimen.
When focusing on a specimen do you always focus toward the specimen?

What the greatest step toward the discovery cells?
The invention of a Microscope.
Which of these is a good focusing question to ask about a work f fiction when preparing to write a genre interpretation essay comparing and contrasting attitudes toward childhood?
Does the tone of the work reveal anything about the narrator's attitude toward childhood? What elements of the work communicate the narrator's attitude toward children. (apexx) All of these are good focusing questions.
An amoeba moving toward a food source is what?
Using a microscope, you observe an amoeba moving toward a food source. This is an example of responsiveness. Endocytosis produces a structure called a food vesicle.
A good focusing question to ask about a work of fiction when preparing to write a genre interpretation essay comparing and contrasting attitudes toward childhood?
One good focusing question could be: "How do different characters in the story portray or experience childhood and how does this shape the overall themes and messages of the work?"

What is the resolution power of a transmission electron microscope?
The Transmission Electron Microscope (TEM) was the first type of Electron Microscope to be developed and is patterned exactly on the Light Transmission Microscope except that a focused beam of electrons is used instead of light to "see through" the specimen. It was developed by Max Knoll and Ernst Ruska in Germany in 1931.The first Scanning Electron Microscope (SEM) debuted in 1942 with the first commercial instruments around 1965. Its late development was due to the electronics involved in "scanning" the beam of electrons across the sample. TEM focus a beam of electrons through a specimen while SEM focus a beam of electrons onto the surface of a specimen and the image provided is 3-Dthe transmission microscope magnifies 300,000 more times and the scanning microscope only magnifies 100,000 more the transmission gives the image of the inside and the scanning microscope gives a 3D image of the surface of the specimen
How does a scanning electron microscope produce images?
The scanning electron microscope (SEM) is a type of electron microscope that images the sample surface by scanning it with a high-energy beam of electrons in a raster scan pattern. The electrons interact with the atoms that make up the sample producing signals that contain information about the sample's surface topography, composition and other properties.
What direction do the object appear when the stage is shifted towards you?
The object appears to move up and away from you as you shift the stage toward you in a microscope.
