When looking at a specimen on your slide, you should always start with the

• low objective lens
• medium objective lens
• high objective lens
• super extra high power lens

When looking through your microscope, you move your slide to the right- It appears

• to move to the right
• to stay the same
• to move to the left
• vanish
