Examples of clues that use the senses to indicate hazardous materials include:

a. Fire or vapor clouds,

b. A hissing sound,

c. Visible sign of corrosion

Explanation:

Hazardous materials are materials that have the potential or ability to causes harm to a person or their environment either by itself or when they come in contact with other materials.

Hazardous materials can come in form of solid, liquid or gas.

We have 3 types of hazards:

a. Physical hazards

b. Chemical hazards

c. Biological hazards.

The classes of hazardous materials that we have include:

a. Flammable solids

b. Radioactive materials

c. Gases

d. Corrosives materials such ad Acidic or Alkaline materials

e. Flammable and combustible liquid materials.

f. Toxic and infectious materials

g. Oxidizing materials and peroxides

h. Aerosols

Clues which we can use to detect the presence of hazardous materials in our environment includes:

a. Our senses(sensory organs)

b. Detection devices

c. The labels on the containers of certain products

d. Container shapes

e. Colours or markings placed on containers

f. Occupancy or Location of the hazard

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

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.
