They produce neurotransmitters that affect mood.

They are thread-like structures made of DNA that contain our genes.

They regulate hormone release in the endocrine system.

They insulate neurons to speed up electrical impulses.

Genes are broad blueprints, while chromosomes are specific instructions.

Chromosomes are segments of DNA that code for traits, while genes are the structures containing DNA.

Genes are specific segments of DNA that code for traits, while chromosomes are structures made of DNA that contain genes.

Chromosomes are only present during embryonic development, while genes are active throughout life.

Humans are simply irrational and make poor dietary choices.

Food preferences are solely determined by cultural influences and marketing.

Modern food processing techniques have altered our taste buds, leading to these preferences.
