The bacteria on Ravi’s unknown slant are beige (light tan). He concludes that given the unknown key above that he does not need to do any further testing to determine his unknown. Which of the following statements are true about his conclusions?

Ravi is incorrect. He would need to carry out Carbohydrate Fermentation to get enough data to make the correct choice

 

Ravi is incorrect. Pigment is never enough information to identify an unknown.

 

Ravi is incorrect. He needs to do a Gram stain to come to the correct conclusion.

 

Ravi is correct. Because his bacteria do not have any pigment, there is only one organism it can be.

 

Question 14

Conduct an Ames test to determine if a new chemical, ChemicalX, is a mutagen. You have two sets of plates with low histidine media. The plate with the bacteria that were not treated with ChemicalX before plating (the control) have two revertants, while the plate with bacteria treated with ChemicalX has 25 colonies. What can you conclude from these data?
ChemicalX is not a mutagen because it has not induced more mutations that enable to the bacteria to make their own histidine.
ChemicalX is a mutagen because this test shows that it causes cancer.

 

ChemicalX is a mutagen because it has induced more mutations that enable to the bacteria to make their own histidine.
ChemicalX is not a mutagen because this test shows that it does not cause cancer.

Question 15

A BIOL107 student, when shown the plant cell above, determined that water would flow into the cell and that the cell would burst. Which of the following is the mistake this student made?

Water would flow towards the outside of this cell, not the inside.

This cell has a cell wall, so it would not burst.

Bursting only occurs when the solute inside is 10% or higher.

Water flows towards the hypotonic solution, not the hypertonic solution.

Bacillus subtilis only because it is Gram-positive and described as bacilli.
Escherichia coli only because it is Gram-negative and described as bacilli.
Pseudomonas aeruginosa only because it is Gram-negative and described as bacilli.
