RAC 40 Quiz 7 Review | Latest Update | 2024/2025 | 100% Verified What is the key difference between soldering and brazing? Soldering occurs below 840°F, while brazing takes place at temperatures above 840°F. Why is flux used in both soldering and brazing? Flux removes oxides from the metal surface and prevents further oxidation during the heating process. What is the purpose of capillary action in brazing? Capillary action draws the molten filler material into the joint betw...

All corrosion of iron at normal ambient conditions is - an electrochemical process The cathode of a corrosion cell - has an opposite electrical polarity to the anode Based on the galvanic series presented in the NACE CIP Level 1 Manual, which three can be used effectively as galvanic anodes for carbon steel? - Zinc, aluminum, magnesium A corrosion inhibitor is a substance that, when added to an environment - decreases the rate of corrosion A decrease in temperature will generally cause the...

A; Animals serve as a reservoir of infection" is the correct answer because Shigella only infects humans while Salmonella is found in many animals. Both have diarrhea as the major symptom. Endotoxin is produced by all gram negative bacteria and exotoxin is only produced by Shigella. A major difference between Salmonella enterica and Shigella infections is that only in salmonellosis can: A. animals serve as a reservoir of infection B. diarrhea become the major symptom C. endotoxin play a ...
