Answer:

The answer is: Electron microscope.

Explanation:

To obtain the maximum magnification and the best resolution, the electron microscope must be used, which can reveal details of up to a few nanometers (nm).

When the thin cuts are sectioned, stained and observed with the electron microscope, a delicate membrane, about 5 nm thick, that surrounds the cell is visualized.

The answer is: Electron microscope.

Answer:

Electron microscope

Explanation:

Instead of using light, it utilized a beam of electron for illumination. Because an electron beam has a shorter wavelength than light (up to 100, 000 times shorter), they have a higher resolution power and are therefore able to view sub-cellular structures including DNA.

Answer:

Endomysium

Explanation:

Endomysium is a thin layer of loose connective tissue which surrounds an individual myocyte or muscle fiber. Collagen is one of the most abundant protein found in this layer. Endomysium also connects the near by muscle fibers to each other. These fibers are then able to exchange various ions necessary for muscle contraction.

Above the level of endomysium, there is perimysium which forms the covering of a bundle of muscle fibers. Even above this level is epimysium which covers the whole muscle.

Which is a purpose for which a pedigree chart might be prepared? to determine the gender of a fetus to determine if a fetus has

Anarel [89]

The purpose for which a pedigree chart might be prepared is to identify the pattern of inheritance of a particular trait.
This pedigree chart is created so as to see which traits this new offspring has inherited from its ancestors and which may possibly be transferred onto a new offspring later on in its life. It is formed in order to find patterns of inheritance and see what the most important traits that get inherited are.
