Which of the following is a non-communicable disease that affects the skeletal system by causing bones to become brittle and prone to fractures?
Show answer
Answer: B. Osteoporosis
Osteoporosis is a condition where bones lose density and become weak, increasing the risk of fractures. It is a non-communicable disease as it is not transmitted from person to person. Influenza, Tuberculosis, and Malaria are all communicable diseases.
Maintaining proper posture is important for spinal health and preventing back pain. Which of the following is NOT a recommended practice for good posture?
Show answer
Answer: B. Slouching forward while working at a desk
Slouching puts undue stress on the spine and can lead to back pain and poor posture. Sitting upright, keeping feet flat, and taking breaks are all recommended practices for maintaining good posture.
The spread of vector-borne diseases can be controlled by managing the vectors. Which of the following insects is a common vector for transmitting malaria?
Show answer
Answer: B. Mosquito
Mosquitoes, specifically the Anopheles species, are the vectors that transmit the malaria parasite from an infected person to another person through their bite. Houseflies, cockroaches, and ants are not primary vectors for malaria.
Which of the following is a crucial practice for preventing the spread of germs on surfaces in public places?
Show answer
Answer: C. Wiping down frequently touched surfaces (like doorknobs) when possible
Regularly cleaning and disinfecting frequently touched surfaces in public spaces helps to reduce the concentration of germs, thereby minimizing the risk of transmission. Touching surfaces frequently, avoiding sanitizer, and openly sharing personal items all increase the risk of germ spread.
Proper sanitation of drinking water is vital to prevent waterborne diseases. Which of the following methods is effective in killing most bacteria and viruses in water?
Show answer
Answer: C. Boiling
Boiling water to a rolling boil for at least one minute kills most harmful microorganisms, including bacteria and viruses, making it safe to drink. Simple filtration might remove some particles but not necessarily all pathogens. Aeration and adding salt are not primary methods for water disinfection.
