how to sign the word aerobiological

To sign the word “aerobiological,” form the letter “a” with your dominant hand and rotate it in a circular motion near your nose to represent the word “air.” Then, make the letter “b” with both hands and move them away from your face to represent the word “biology.” Lastly, use your dominant hand to make the letter “o” and place it near your mouth to represent the word “organism.” Put all three signs together to complete the word “aerobiological.”
