Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

13 notecards = 4 pages (4 cards per page)

Which of the following statements is relevant in explaining why sulfonamides are effective?

  1. sulfonamides attach to sterol lipids in the pathogen, disrupt the membranes, and lyse the cells
  2. sufonamides prevent the incoporation of amino acids into polypeptide chains

front 5

Cross resistance is _____________

  1. the deactivation of an antimicrobial agent by a bacterial enzyme.

  3. the mutation of genes that affect the cytoplasmic membrane channels so that antimicrobial agents cannot cross into the cells interior
  4. resistance to one antimicrobial agent because of its similarity to another antimicrobial agent

back 5

d. resistance to one antimicrobial agent because of its similarity to another microbial agent
