In a single day, two 19 year old women and one 20 year old man sought treatment at a university health clinic, complaining of ac

ute diarrhea, nausea and vomiting. No blood was found in their stools. One of the women was found to have a UTI. All three had eaten lunch at a nearby health food store the previous day. The man had a turkey sandwich with tomato, sprouts, pickles and sunflower seeds. One woman had a pocket sandwich with turkey,sprouts, and mandarin oranges; the other woman had the lunch special, described in the menu as a "delightful garden salad of fresh organic lettuces, sprouts, tomatoes, and cucumbers with zesty raspberry vinaigrette dressing". All had bottled water to drink. Which of the foods is the most likely source of the infections? What media would you use to culture and isolate enteric contaminants in the food? Which enteric bacteria could cause these symptoms? What would be the appearance of this organism on this media?

Genetically-modified organisms (GMOs) have included corn crops engineered to produce a natural pesticide to kill a certain insec
dimulka [17.4K]

The correct answer is option C, that is, the insects could grow resistant to the pesticide in the genetically-modified corn and become immune to regular pesticides.  

The genetically modified organisms are usually developed to be more resistant to pesticides or produce pesticides themselves. The GM crops do not have monarch butterflies or honeybees. However, the insects that consume genetically modified crops can, in some of the circumstances, begins to establish a resistance to the protein that usually kills them.

A different DNA ladder from NEB (Cat #N3200L) comes as 500 uL of a 1000 ug/mL solution and is not pre-mixed with the 6 X DNA loa
JulijaS [17]

Answer:

4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder

Load 12 ul on the gel.

Explanation:

DNA Ladder concentration = 1000 ug/ml

1000 ug DNA in 1 ml DNA Ladder solution →    150 ng DNA = 0.15 ug DNA in..... 0.00015 ml = 0.15 ul DNA Ladder solution

6x DNA Loading Buffer → it has to be diluted by an equal volume 6 times (1 ul LB + 1 ul distilled H2O)

An appropriate volume to load on an average agarose gel is 12 ul, so:

2 ul Loading Buffer + 9.85 ul dH2O + 0.15 ul DNA Ladder = 12 ul

But since 0.15 ul is a very small volume and mistakes could be made while measuring it, let's make double:

4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder = 24 ul

And load half of that solution (12 ul) on the gel.

A simplified model of the human blood-type system has four blood types: a, b,ab and o. thereare two antigens, anti-a and anti-b.
Kay [80]
First calculate the probability of type AB, which is the remainder after subtracting types A, B and O.

P(AB) = 1-(0.34+0.12+0.5) = 1-0.96 = 0.04

Anti-b will react with types B and AB, so 
P(reaction) = P(B)+P(AB) = 0.12 +  0.04 = 0.16

Answer: For this person, the probability of reaction with anti-b is 0.16
