Question

Scientists have genetically engineered potato plants to produce potatoes that contain edible vaccines. Which is a disadvantage of the genetically engineered potatoes?
They are easier to transport and store than injectable vaccines (shots).
They make it easier to administer edible vaccines.
They are more expensive than potatoes without the vaccine.
They have nutritional value while potatoes without the vaccine do not.

Answer 1

They are more expensive than potatoes without the vaccine.

Reason: producing and regulating genetically engineered crops and vaccines increases development, production, and regulatory costs, making them pricier than ordinary potatoes.
