1
Q
Three principles of cell theory
A
composed of one or more cells, basic unit of life and that cells arise from preexisting cells
2
Q
If the measured object is 6cm in length under a microscope but 2cm in actual size what is the magnification
A
- Magnification=measured/actual size therefore
3=6/2
3
Q
If magnification is 5cm but the measured size is 250cm what is the actual size
A
50cm. Actual size=size of image/magnification
50=250/5
4
Q
if measured the object is 56cm. But 7cm in actual size. What is the magnification?
A
- Magnification=measured/actual. Therefore
8=56/7
5
Q
If actual size is 6cm but the magnification is 20. what is the measured
A
6x20=120
6
Q
Magnification is 4 but the measured size is 64cm
A
- 64/4
7
Q
If the actual size of the image is 3 but the measured size is 36. What is magnification
A
12
