Answer: Bacteria gain resistance to drugs because of mutations (permanent and random changes to their DNA) which means they have changed DNA coding, giving them the ability to resist the drug fighting them off. As a result, they survive and reproduce. Over time, more and more bacteria are generated as the DNA code for resistance is passed on over generations. This results in bacteria having the ability to resist drugs. This is particularly prevalent with antibiotics.
An athlete would have a larger vital capacity than a non-athlete aerobic ability would find people with larger lungs and hence a bigger vital capacity. The vital capacity of an athlete is higher than a non-athlete because they are trying to do hard work their legs to get bigger and bigger over time making it easier for them
Answer:
B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present
Explanation:
Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.
Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.
Whispered pectoriloquy is used to detect vocal resonance. It is used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.
