Fat metabolism is highest during low-intensity exercise. When engaging in low-intensity activities, such as walking or light jogging, the body primarily relies on fat as its fuel source. During low-intensity exercise, the body can efficiently utilize stored fat as an energy substrate.

At low exercise intensities, the body can supply the necessary energy demands through aerobic metabolism, where oxygen is readily available. Fat is broken down through a process called lipolysis, releasing fatty acids that are then transported to the muscles for energy production.

In contrast, during higher-intensity exercises, such as sprinting or intense weightlifting, the body relies more on carbohydrates as a fuel source. This is because the demand for energy is higher, and carbohydrates can be rapidly broken down to provide quick energy through anaerobic metabolism. During intense exercise, the body's ability to utilize fat as a fuel source is reduced.

It's important to note that while low-intensity exercise promotes fat metabolism, higher-intensity exercises can still contribute to overall fat loss by increasing total calorie expenditure and improving metabolic rate. Balancing different exercise intensities can be beneficial for overall fitness and weight management goals.

Explanation:

Out of the given options, the blood sample that does not settle at all in one hour is the individual with sickle cell anemia.

Sickle cell anemia is a genetic disorder that affects the shape of red blood cells. In individuals with sickle cell anemia, the red blood cells have a crescent or sickle shape, which makes them sticky and prone to clumping together. This clumping can cause blockages in the blood vessels, leading to reduced blood flow and tissue damage.

Due to the abnormal shape and stickiness of the red blood cells, they tend to stack together and resist settling down, leading to a turbid appearance and no settling at all in one hour.
