Answer 3

no

Question 4

Answer 4

cell wall, pili (adheres to substances), flagella (tails)

Question 5

Question 7

Answer 7

true

Question 8

eukaryotic cells contain a…

Answer 8

nucleus and membrane-bound organelles, making them more complex

Question 9

magnification

Answer 9

how much bigger the image is than the specimen

Question 10

magnification is calculated by…

Answer 10

multiplying the magnification of objective lens with magnification of ocular lens

Question 11

resolution

Answer 11

the ability to distinguish between two points that are close together

Question 12

Field of View (FOV)

Answer 12

the diameter of the circle of the view you can see when looking down a microscope

Question 13

FOV can be calculated by…

Answer 13

a tiny ruler printed into the surface, known as a “minigrid”. As magnification increases, FOV decreases
