33) Two cells that are 100 am apart can be observed separately by the natural human eye Type: TF ae Rf 2-55 Topic: resolution Skil: Requires Analysis 34) When empty magnification increases, resolution remains the same Type: TF Page Ref: 55GG Topic: resolution Demons 35) The Scanning Electron Microscope magnifies the image of a specimen with a Scanning Objective lens Type: TF Page Ref: 57-67 Topc: electron microscopy Skiit Requires Recollection 36) In a Transmission Electron Microscope, electrons travel right through a specimen, while electrons only pass over the surface of the specimen in a Scanning Electron Microscope Type: TF Page Ref:57-67 Topic: electron microscopy Skilt: Requires Recollection 37) Human, Animal, and Plant cells are measured in micrometers, while the sizes of Bacterial cells are expressed in nanometers Type: TFPage Ref: 52-55 Topic: measurements Skill: Demonstrate Understanding 38) Most microscope characteristics change with magnification, except the body tube that remains at 160 mm long for every objective lens. Type: TF Page Ref: 55-66 Topic: lens property Skill: Requires Analysis 39) A microscope will reveal more details when its illuminator uses longer wavelength light to produce an image of the specimen. Type: TF Page Ref: 55-66 Topic: microscopy skill: Demonstrate Understanding 40) Final image can be magnified 10,000 times with either Transmission or Scanning or Electron Microscopes. Type: TF Page Ref: 58-67 Topic: electron microscopy Skill: Demonstrate Understanding

Answer 1

33. Smallest size visible to human eye is 0.1 mm. So we can not see the cells separately.

ANSWER: False

35. Scanning electron microscope uses scanning objective lens for scanning.

ANSWER: True
