1 Which statements about resolution and magnification are correct?
resolution magnification
A the ability to distinguish between two the number of times larger an image is
separate objects that are very close compared with the real size of the object
together
B the clarity of the image formed the power of the microscope to focus
by the microscope on very small objects
C the number of times larger an image is the ability to distinguish between two
compared with the real size of the object separate objects that are very close
together
D the power of the microscope to focus the clarity of the image formed
on very small objects by the microscope
2 An eyepiece graticule has a scale with 100 divisions. A stage micrometer has a scale with
50 divisions, each of which is 0.040 mm apart.
Using a ×40 objective lens, the whole length of this stage micrometer scale lines up with
15 divisions of the eyepiece graticule.

4 A scientist carried out an experiment to separate cell structures in animal cells.
The cells were broken open to release the cell structures.
This extract was filtered into a centrifuge tube and then spun in a centrifuge. The heaviest cell
structure sank to the bottom forming pellet 1, as shown in the diagram.
liquid above
pellet
pellet 1
The liquid above pellet 1 was poured into a clean centrifuge tube and spun in the centrifuge at a
higher speed to separate the next heaviest cell structure. This cell structure sank to the bottom,
forming pellet 2.
This procedure was repeated twice more to obtain pellet 3 and pellet 4, each containing a single
type of cell structure.
Which row shows the order in which the cell structures were collected?
pellet 1 pellet 2 pellet 3 pellet 4

B nucleus mitochondria lysosomes ribosomes
C ribosomes lysosomes mitochondria nucleus
D ribosomes mitochondria lysosomes nucleus
