Answer:
The correct options are a, b, d and f
Explanation:
From the question, several of the options are potential hazards one might encounter in the laboratory. For example,
a. <u>Microbiologists</u> working with infectious microorganisms need to be extremely careful while handling these microbes and will need to put on personal protective equipment (PPE) as <u>these organisms constitute a potential health hazard to them</u>.
b. <u>Open flames constitute a potential fire hazard</u>; this is because there are several chemicals in the laboratory that are inflammable and will need to always be kept at a reasonable distance away from open flames.
d. <u>Corrosive chemicals constitute a potential reactivity hazard</u> thereby causing burn to the skin. Strong acids and bases are especially culpable of this in the lab. The lab scientists will need to put on overall/PPE to prevent this causing harm them.
f. Although least likely, <u>gamma radiation</u> can also be emitted from nuclear medicine studies <u>causing potential health hazard</u>, as it is capable of destroying/damaging the DNA of cells or even causing damage to the cell itself.
Answer:
"Helps fight off infection" protein doesn't do that. Your white blood cells is what fights that for you.
