Why do you have to determine the total magnification when observing a specimen under the compound microscope?
IceJOKER [234]

Answer:

To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.

Explanation:

A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.

What can you learn about a sample from an sds-page analysis?
puteri [66]

Option <u>(c.) the purity of the protein</u>, will be the right one.

Sodium Dodecyl Sulphate provides a negative charge to each protein as a function of their molecular size. It is an anionic detergent, as well as it is there to determine the relative abundance of major proteins.

After denaturing, proteins get unfolded and gets coated with SDS detergent molecules. The SDS-PAGE technique is used for the separation of protein based on their molecular size/weight/mass.

It is so because as it identifies the proteins by its molecular weight. Therefore, SDS is used in denaturing polyacrylamide gel electrophoresis for the determination of protein molecular weight, the SDS-PAGE is a technique.
