1. Answer;
Light microscope (LM)
Explanation;
-A light microscope (LM) is an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye, or in finer detail than the naked eye allows.
-It allows attachment of the focus wheels and the stage to the microscope. A light source used in place of a mirror. Most microscopes do allow manual light adjustment via a wheel located near the base.
2. Answer;
Scanning electron microscope (SEM)
Explanation;
-A scanning electron microscope (SEM) scans a focused electron beam over a surface to create an image. The electrons in the beam interact with the sample, producing various signals that can be used to obtain information about the surface topography and composition.
-There are two main types of electron microscope; the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image.
<h2>Let us study about adaptation </h2>
Explanation:
Characters are certain features that are inherited from parents .
But all characters are not passed from parents to offspring .
There are certain variations also shown by an individual as compared to parents .
There are certain characters or features that are developed in organism not as a result of heredity or variation . They are refereed as Adaptation .
Adaptations
They are the certain characters that are developed in an organism according the conditions in which it survives .
The organism adapt to environmental condition in order to survive better and cope up better with the surroundings .
Ummmm... from my book females have wider area 90 degrees or something like that, while males have slimmer area like 60 degrees or something. Obviously not everyone has that type of area surface but I think ?typically? They are around those degrees.
Well, hope this helps you even though it is all weird and stuff
