If I have to remove the red blood cells from a blood agar plate (BAP), then I have to use the "Chocolate agar plate".
If you were to remove the red bloods cells from at blood agar plate (BAP), what...
E. coli cells were spread on two agar plates [one containing only agar (plate 1) and the second containing streptomycin (plate 2) which kills all cells except those that are resistant mutants]. Both plates were allowed to grow for several generations. Cells were collected from the agar plate WITHOUT streptomycin and spread again on a fresh agar plate containing streptomycin (plate 3). More mutants were observed on plate 3 than were observed on plate 2. The experiment demonstrates A. how...
Question 7 (1 point) Saved After steaking a sheep blood agar plate with a throat swab, the purpose of stabbing the inoculum inot the agar (or placing in an anaerobic jar) is to: O provide reduced oxgyen tension for better growth obtain isolated colonies of respiratory flora clean off the inoculating loop enhance the beta-hemolytic activity of the pathogen - Question 11 Respiratory culture has the folloiwng results on BAP. 1. Alpha-hemolytic 2. G (+) lancet shaped cocci 3. catalase...
How would you verify that the colonies that grew on a MacConkey agar plate were Gram negative? What types of bacteria are inhibited on MacConkey agar?
A microsope slide showing agglutination when blood is mixed with antisera. our red blood cells are much stronger antigens and large aggregated clumps will be readily visible when agglutination has occurred. If you have neither A nor B antigen on your red blood cells, you will have no agglutination of either antisera and therefore the cells are blood type 0. Figure 4 shows a picture of aggluti-nation when cells clump or aggregate. No agglutina-tion is a smooth suspension of cells...
you have cultured a throat swab specimen on a blood agar plate. you note the presence of a clear halo around the colonies. these bacteria are exhibiting (a) endoenzyme production for hemolysis (b) exoenzyme production for hemolysis (c)exoenzyme production for for iron reduction (d) lactose fermentation (e) mannitol fermentation
Red blood cells often can be charged. Two red blood cells are separated by 1.24 m and have an attractive electrostatic force of 0.974 N between them. If one of the red blood cells has a charge of +8.56 10-6 C, what is the sign and magnitude of the second charge, Q?
Red blood cells often can be charged. Two red blood cells are separated by 1.36 m and have an attractive electrostatic force of 0.980 N between them. If one of the red blood cells has a charge of +8.32 10-6 C, what is the sign and magnitude of the second charge, Q?
How do the sickled red blood cells vary from the normal red blood cells? How might this affect their ability to serve within the circulatory system?
Red blood cells can often be charged. Consider two red blood cells with the following charges: -15.8 PC and +45.6 p. The red blood cells are 3.52 cm apart. (1 pc - 1 x 10-12 C.) (a) What is the magnitude of the force on each red blood cell? N Are the red blood cells attracted or repulsed by each other? attracted repulsed (b) The red blood cells come into contact with each other and then are separated by 3.52...
