Studying For Science

Question 0

Total magnifications

Answer 0

40x, 100x, 400x, 1000x

Question 1

All magnifications

Answer 1

4x, 10x, 40x, 100x

Question 2

Field sizes

Answer 2

4000 um, 1600 um, 400um, 160 um

Question 3

How do you calculate the field size of a specimen

Answer 3

You take the field size and multiply it by how much width of the circle the specimen is taking up
Example 4000um x .75 = 3000 um

Question 4

How to calculate the magnification of a specimen

Answer 4

You take the width of the specimen (make sure they both have same measurements like um) and divide it by the actual specimen size

Question 5

What does it mean when it says stem cells are undifferentiated

Answer 5

It means they have not become any particular type of cell and can still become any type of cell.

Question 6

Every cell has identitical identity so why do different cells go to different tissues

Answer 6

They go to different tissues because different genes are “turned on” in different cell types to send it into different development paths.

Question 7

What are the three components of the cell theory

All cells come from preexisting cells
Cells are the smallest unit of life
All organisms are made up of one or more cells
