What part are you going to manipulate for the specimen to have a sharper focus? A. Mirror B. Fine adjustment knob D. Inclination joint C. Stage clips 2. Forceps are used to hold and fix the specimen on the glass slide. What household material can be used if you don't have any forceps? A. Fork B. Tweezer C. Spoon 3. The formula of total magnification (MT) is the product of magnification of the eyepiece (ME) and magnification of the objective lenses (Mo) like LPO, MPO, or HPO. Which equation represents the statement? A. MT = ME(Mo) C. MT = ME + Mo 4 Compute for the total magnification of an onion skin if the eyepiece has 4X magnification and the LPO has a magnification of 10X. А. 40X C. 2.5X D. Tong B. MT = ME- Mo D. MT = ME/Mo В. 14X D. 6X 5. Solve for the magnification of the eyepiece if the total magnification is 150X and the LPO has a magnification of 10X. A. 1500X В. 160X С. 15X 6.
