PROBLEM: Question: The most appropriate microscopy to identify Treponema pallidum in exudates from syphilitic lesions is:
Options: <0> Clear field without staining. <1> Clear field with simple staining. <2> Dark field <3> Phase contrast. <4> Polarized light

SOLUTION: biology

PROBLEM: Question: In an electrochemical cell, the supporting electrolyte serves to:
Options: <0> That the principle of electroneutrality in the dissolution is fulfilled. <1> That their ions are electrolized preferably in order to prevent the consumption of electroactive substance. <2> That in the cell there is transport by migration, in order to achieve greater sensitivity. <3> That the solution has an adequate electrical conductivity. <4> Encourage transport by diffusion of the electroactive substance.

SOLUTION: chemistry

PROBLEM: Question: A 47-year-old man consulted for edema in lower limbs of 3 weeks of evolution. In blood analysis, creatinine 1.3 mg / dL, total cholesterol 270 mg / dL and albumin 2.4 g / dL.
