Answer:
Transmission electron microscope (MET): allows sample observation in ultra-thin sections. A TEM directs the electron beam towards the object to be increased. A part of the electrons bounce or are absorbed by the object and others pass through it forming an enlarged image of the specimen. To use a TEM, the sample must be cut into thin layers, not larger than a couple thousand thousands of angstroms. A photographic plate or a fluorescent screen is placed behind the object to record the enlarged image. Transmission electron microscopes can increase an object up to a million times.
A scanning electron microscope creates an enlarged image of the surface of an object. It is not necessary to cut the object into layers to observe it with an SEM, but it can be placed in the microscope with very few preparations. The SEM scans the image surface point by point, unlike the TEM, which examines a large part of the sample each time. Its operation is based on traversing the sample with a very concentrated beam of electrons, similar to the scanning of an electron beam on a television screen. The electrons in the beam can disperse from the sample or cause secondary electrons to appear. Lost and secondary electrons are collected and counted by an electronic device located on the sides of the specimen. Each point read from the sample corresponds to a pixel on a television monitor. The higher the number of electrons counted by the device, the greater the brightness of the pixel on the screen. As the electron beam sweeps the sample, the entire image of it is presented on the monitor. Scanning electron microscopes can enlarge objects 200,000 times or more. This type of microscope is very useful because, unlike TEM or optical microscopes, it produces realistic three-dimensional images of the object's surface.

Answer:
<em>Candida albicans</em>
Explanation:
Yeasts cause candidiasis is a fungal infection. It is caused by yeast genus <em>Candida</em>. The most common species of yeast which cause candidiasis is the <em>Candida albicans</em>. It habitats in the mouth, throat, gut, and vagina of the human body. The yeast genera can cause infection if they make entry to the bloodstream when their growth becomes uncontrolled. If also they enter into internal organs such as kidney, heart, brain cause candidiasis.
Answer:
My guess would be C
Explanation:
The crust, which is Earths outer solid layer of rock, is around 20km thick if I remembered correctly, and the ocean is nowhere near that, so there would be rock under the ocean.
If you find a better answer, then use it, because I'm not completely sure, but that's my best guess based on the possible answers
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
