what are the effects of protein-calorie malnutrition?
□ death is common.
□ infections often develop.
□ adults are more commonly affected.
□ physical and mental growth may be permanently retarded.

Explanation:

• For "death is common": Severe protein - calorie malnutrition can lead to organ failure and other life - threatening conditions, so death is a common outcome in severe cases.
• For "infections often develop": Malnutrition weakens the immune system, making the body more susceptible to infections.
• For "adults are more commonly affected": Protein - calorie malnutrition is more common in children (especially in developing countries due to lack of proper nutrition), so this statement is incorrect.
• For "physical and mental growth may be permanently retarded": In children, lack of proper protein and calories during growth periods can lead to stunted physical growth and cognitive impairments that may be permanent.

Answer:

A. death is common.
B. infections often develop.
D. physical and mental growth may be permanently retarded.
