Verified answer

4.

Most bacteria cause disease. (3 points)

B) False - most bacteria are normal flora and do not make us sick

5.

What infectious, *bacterial* diseases could be spread by failure of people to adequately wash their hands? (3 points)

C) salmonella - the other three choices are VIRUSES

Most bacteria don't cause disease. Most of them belong to the normal human flora (although I agree that the term indigenous microbiota is more correct.) The correct answer is B.

Diseases that can be transmitted through fecal-oral ways are spread by salmonella, but mostly by Escherichia Coli since it is located in the colon and if the hygiene is not inadequate, it can cause an infectious disease (though part of the indigenous microbiota, E. coli can cause infection in the urinary tract if it moves with it's flagella out of it's habitat). The correct answer from the given options is C.

a million. Antibiotics will kill dwelling bacterial cells. Viruses do no longer meet all the standards to be seen alive*. 2. We study viruses in biology because of the fact they have considered one of those extensive effect upon dwelling issues on our planet. they're able to mutations according to their taking earnings of obtainable dwelling issues. *characteristics of existence simplified S-synthesis (being able to make components like using amino acids to make protein) T-transport (the skill to go food and different molecules around our bodies) E-excretion (doing away with waste) R-respiratory (gas substitute like oxygen for carbon dioxide) N-food (having some form of weight loss plan) G-improve (a collection development of progression) R-reproduction R-regulation (being able to maintain homeostasis)
