Answer 1

Chemicals can enter the body through respiration, inhalation, skin absorption, and skin penetration.

Step-by-step explanation:

The correct answer is a. respiration, inhalation, skin absorption, and skin penetration.

Chemicals can enter the body through the respiratory system by being inhaled into the lungs. They can also enter through the skin, either by being absorbed or penetrating through the skin barrier. Lastly, chemicals can enter through ingestion, when they are swallowed and enter the digestive tract.
