Answer

  1. The candle light went out in container B due to a lack of oxygen, which is necessary for combustion.

  2. The similarity between the narrow bend of a clinical thermometer and the valves in the human heart is that both prevent backflow; the thermometer prevents mercury from falling back, while heart valves prevent blood from flowing backward.

  3. One possible cause of food insecurity in a society is drought, which can lead to crop failure and reduced food supply.

  4. One practice that can be done by a patient to make swallowing of essential drugs in the form of tablets easy is to drink water before and after taking the tablet to help it go down smoothly.

  5. The item used by farmers to check on the decomposition process during the making of compost manure is a thermometer.

  6. The use of the above item (funnel) to a shopkeeper is to transfer liquids or fine-grained substances into containers with small openings.

  7. One proper way of using the above item (funnel) is to hold it steadily in the container's opening to ensure that the liquid or substance flows smoothly without spilling.

  8. It is important for HIV/AIDS positive mothers to give birth in hospitals under the supervision of health workers to reduce the risk of mother-to-child transmission of the virus and to ensure proper medical care for both mother and child.
