The independent variable is the age of the students because it’s what affects their ability to be better drivers. The driving-level is dependent on their age. :)

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.

imagine a model of a cell shaped like a cube.Calculate the ratio of surface area to volume for a cell model measures 3 cm on eac
Svet_ta [14]
Smaller cube (1 cm X 1 cm X 1 cm) 

<span>The surface area of one side = 1 cm X 1 cm = 1 <span>cm2</span></span>

 

<span>There are 6 sides, total SA = 6 X 1 <span>cm2</span> = 6 <span>cm2</span></span>

 

<span>Volume = 1 cm X 1 cm X 1 cm = 1 cubic cm (1 <span>cm3</span>)</span>

<span>Surface to Volume Ratio = 6 <span>cm2</span>/1 <span>cm3</span> = 6 <span>cm2/cm3</span></span>


Larger cube (6 cm X 6 cm X 6 cm) 

<span>The surface area of one side = 6 cm X 6 cm = 36 <span>cm2</span></span>

 

<span>There are 6 sides, the total SA = 6 X 36 <span>cm2</span> = 216 <span>cm2</span></span>

 

<span>Volume = 6 cm X 6 cm X 6 cm = 216 <span>cm3</span></span>

 

<span>Surface to Volume Ratio = 216 <span>cm2</span>/216 <span>cm3</span> = 1 <span>cm2/cm3</span></span>
