The diagram below represents a hydra as viewed with a compound light microscope. * If the hydra moves toward the right of the slide preparation, which diagram best represents what will be observed through the microscope? 1) 3) Why is this a preferred procedure? 1) The coverslip will prevent the slide from breaking. 2) The organisms will be more evenly distributed. 3) The possibility of breaking the coverslip is reduced. 4) The possibility of trapping air bubbles is reduced. 7. A cell in the field of view of a compound light microscope is shown in the diagram below. 2) 4) In which direction should the slide be moved to center this cell in the microscopic field? 1) to the right and up 3) to the left and up 2) to the right and down 4) to the left and down The diagram at the right represents a strand of algae viewed under the low-power objective of this microscope. Under the high-power objective, how would this same slide appear? 1) 3) 8. Which structure in a stained cheek cell would most likely be visible when viewed through the high-power objective of a compound light microscope? 1) cell wall 3) chloroplast 2) ribosome 4) nucleolus TUU 2) 4) 9.A wet-mount slide preparation of a specimen is stained in order to 1) eliminate some organelles 2) make cell structures more visible 3) use the high-power lens 4) remove water from the slid ☺ _10. A coverslip should be used for preparing a 1) frog for dissection 2) solution of iodine for food testing 3) wet mount of elodea (a simple plant) 4) test to determine the pH of a solution 13. A student views some cheek cells under low power, Before switching to high power, the student should 1) adjust the eyepiece 2) center the image being viewed 3) remove the slide from the stage 4) remove the coverslip
