Question

1. if a person is hiv positive, why does he or she need to eat 10% more calories than do his or her noninfected counterparts?hiv - positive people have a high red blood cell count.hiv - positive people use more energyhiv - positive people use less energy.hiv - positive people have a low red blood count.

Explanation:

HIV - positive individuals often have an increased metabolic rate due to the body's response to the virus (such as immune activation). This means they use more energy. Calories are a measure of energy. So, to meet the higher energy demand, they need to consume more calories. A high red - blood cell count is not the reason for increased calorie intake. A low red - blood cell count (anemia) can occur in HIV - positive people but is not the direct cause of increased calorie needs. And using less energy would mean less calorie requirement, which is the opposite of what is needed.

Answer:

HIV - positive people use more energy.
