Which of the following is a benefit to having insulin produced by biotechnology? a. It is just as effective. b. It can be mass-produced. c. It is nonallergenic. d. It is less expensive. e. All of these are correct.

Let's examine each of the provided options to determine the benefits of biotechnologically-produced insulin. a. It is just as effective: Biotechnologically-produced insulin is just as effective as the insulin that is naturally produced by our bodies. This is because the insulin produced through biotechnology is an exact copy of human insulin, so it functions in the same way. b. It can be mass-produced: One advantage of biotechnologically-produced insulin is that it can be mass-produced. This ensures a regular and reliable supply of insulin for people living with diabetes, making it more accessible globally. c. It is nonallergenic: Insulin produced through biotechnology does not have the potential to cause allergic reactions, unlike some other types of insulin. As a result, it is considered safer and better tolerated by most people. d. It is less expensive: The production of insulin through biotechnology is usually more cost-effective than traditional methods. This makes it more affordable and accessible for people with diabetes.

Based on our analysis of the options, we can see that all of the options (a, b, c, and d) are benefits of having insulin produced by biotechnology. Therefore, the correct answer is: e. All of these are correct.
