You need to determine if a pure culture of bacteria is Gram-positive or Gram-negative, but you've just spilled your only solution of crystal violet so you can't do a Gram stain. You decide to try a lysozyme treatment on a sample of each culture and then examine the samples under the microscope. The expected result is:. A. Gram-positives will be unaffected; Gram-negatives will lyse and appear as debris.
B. Gram-positives will be unaffected: Gram-negatives will lose their flagella
C. Gram-positives will lyse and appears as debris: Gram-negatives would also lyse and appear as debris.
D. Gram-positives will lyse and appears as debris: Gram-negatives would have a weakened cell envelope but not lyse.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
