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.
Blood volume. If you are tired and no blood is able to get to your body and you heart keeps going faster your heart is probably going to fail.
