43) The major setback for the use of Transmission Electron Microscope is that: a) You can’t stain the sample with colored dyes b) You can’t see internal structures of the cell c) You can’t focus on Organelles inside the cell d) you can’t focus on cell membranes44) The major advantage of using the Scanning Electron Microscope (SEM) over the Transmission Electron Microscope (TEM) is that: a) You can use live material in looking through the SEM and not the TEM b) You can look at internal structures with SEM & not TEM c) You can use higher magnifications with SEM d) You can look at solid objects with SEM45) The image that you are observing in the SEM comes from: a) Direct reflection/bouncing of electrons from the specimen you are looking at b) Backscattered electros from the secondary electrons from the specimen c) A contrast between the texture of the specimen you are looking at d) A contrast between the acidophilic and basophilic components of the specimen you are looking at46) A cluster of spherical shaped bacteria is called: a) Streptobacillus b) Streptococcus c) Staphylococcus d) Staphylobacillus

43) The major setback for the use of Transmission Electron Microscope is that: a) You can’t stain 
the sample with colored dyes b) You can’t see internal structures of the cell c) You can’t focus 
on Organelles inside the cell d) you can’t focus on cell membranes
44) The major advantage of using the Scanning Electron Microscope (SEM) over the Transmission 
Electron Microscope (TEM) is that: a) You can use live material in looking through the SEM and 
not the TEM b) You can look at internal structures with SEM & not TEM c) You can use higher 
magnifications with SEM d) You can look at solid objects with SEM
45) The image that you are observing in the SEM comes from: a) Direct reflection/bouncing of 
electrons from the specimen you are looking at b) Backscattered electros from the secondary 
electrons from the specimen c) A contrast between the texture of the specimen you are 
looking at d) A contrast between the acidophilic and basophilic components of the specimen 
you are looking at
46) A cluster of spherical shaped bacteria is called: a) Streptobacillus b) Streptococcus c) 
Staphylococcus d) Staphylobacillus
