As a result of competition among friends, Ahmed eats a lot of pakoras, resulting in a rise of salts in the blood, to compensate_ is triggered in the body.
Correct answer: B. Negative feedback
- A. Positive feedback
- B. Negative feedback
- C. Internal feedback
- D. External feedback
Explanation
The correct answer is Negative feedback. This mechanism is crucial for maintaining homeostasis in the body. When there is a rise in salts in the blood, negative feedback mechanisms are triggered to restore balance, such as by increasing water retention or adjusting salt excretion, thus counteracting the initial change. In contrast, Positive feedback would further increase the change rather than compensating for it, and both Internal feedback and External feedback are not relevant terms in the context of physiological regulation for homeostasis.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
