Answer:
A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C
Explanation:
Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).
That automatically eliminates Option B.
I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.
Option D is wrong because it includes no temperatures above body temperature.
Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.
That leaves Option A as the best answer. It includes only one temperature above 40 °C.
A high-fiber diet may improve blood cholesterol because soluble fiber binds to cholesterol and fiber-derived fatty acids reduce cholesterol synthesis. A higher fiber diet is recommended to have a healthy heart.
<h3>Higher fiber diet and heart</h3>
Dietary fiber can be divided into soluble fiber and insoluble fiber.
A higher fiber diet can help to protect your heart because soluble fiber binds to cholesterol, thereby helping to its excretion.
Moreover, fatty acids produced during soluble fiber fermentation can reduce cholesterol synthesis in the liver.
