Use biology in their work. dentists dietitians zoologists all of the above

I think the answer is all of the above

dietitians -> need to learn about human body-> biology

zoologists-> need to learn about animals-> biology

so, since two answers are correct the answer is all of the above

Dentists need to know about the mouth and teeth. Thse involve learning about the human body, so is therefore a branch of biology.

Dietitions learn about the digestive system and is no doubt a branch of biology.

Zoology is the study of animals, and they are living creatures, meaning that this is a branch of biology.

Therefore, the answer to this multiple choice question is All of the Above
