Which of the following could be a biological hazard pesticide fish bone hepatitis a or santizer

Hepatitis could be a biological hazard.

Explanation:

Any microorganism that represents a threat to the health of a worker is considered to be biological risk, and may be either through direct or even indirect contact - as long as there is really a danger of infection or other problems with physical integrity.

Examples of these risks are bacteria, viruses, fungi, protozoa, parasites and other microorganisms that can be exposed to contact with humans. In general, they are more easily identified in hospitals and in health-related areas, such as doctor's offices.

Hepatitis is the inflammation of the liver. It can be caused by viruses or by the use of some medicines, alcohol and other drugs, among other factors. Among the options given in the question above, it is the one that fits the concept of biological risk.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
