Ann [662]

Answer:

Proteins are like carbohydrates and fats (lipids) because they contain carbon, hydrogen and oxygen. On the other hand, proteins also contain _nitrogen__________ while carbohydrates and fats do not.

What is the difference between embolus and thrombus
ryzh [129]
An embolus is anything which travels through the blood vessels until it reaches a vessel that is too small to let it pass through, and this causes the blood flow to stop.    Basically, a thrombus is the blood clot itself, and the embolus is a fraction of the blood clot which travels through the blood vessels.

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.
