An occupational disease caused by the inhalation of certain dust particles is called: dermatosis. none of these is correct. atherosclerosis. pneumoconiosis. caisson disease.

pneumoconiosis

Dermatosis is a condition of the skin, either genetic in nature and influenced by environmental conditions such as an initial infection/ contact dermatitis.

Atherosclerosis is a condition described by hardening of the arteries, affecting the heart. This is a chronic condition, caused by environmental factors (diet).

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
