State one advantage for a person with diabetes to receive genetically engineered insulin rather than insulin taken from a horse or cow

The main advantage of genetically engineered insulin is its species specificity which reduces allergic reactions.

Explanation:

Genetically engineered insulin is also known as human insulin. It is produced by genetically engineered or genetically modified bacteria. It is indistinguishable to natural human insulin release by beta cells of the pancreas so it causes fewer allergic reactions to the patient.

Animal insulin is produced from the pancreas of animals such as cows, horses, and pigs. This produced animal insulin extracted and purified for clinical use.

So, the main advantage of human insulin or genetically modified insulin is its species specificity.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
