Biology Quiz On Health And Hygiene! Trivia

Mr. K attending to his duty and spending time joyfully suggests that he is in a healthy state. This is because he is able to carry out his responsibilities and find enjoyment in his daily activities. In contrast, Mr. X is recovering from an infectious disease, indicating that he is currently unwell. Mr. Y needing to take insulin injections every day implies that he has a medical condition that requires regular treatment. Mrs. Z being very much depressed suggests that she is experiencing mental health issues. Therefore, the only individual in a healthy state is Mr. K.

The correct answer is BCG. BCG stands for Bacillus Calmette-Guérin, which is a vaccine used to prevent tuberculosis (TB) in infants. It is typically administered soon after birth and helps to protect against severe forms of TB such as meningitis and disseminated TB. The BCG vaccine is given as an injection, usually into the upper arm. It stimulates the immune system to produce a response against TB bacteria, providing immunity against the disease.

Tuberculosis is transmitted through the air. It is caused by the bacteria Mycobacterium tuberculosis and primarily affects the lungs. When an infected person coughs or sneezes, they release tiny droplets containing the bacteria into the air. These droplets can be inhaled by others, leading to the transmission of tuberculosis. Other diseases mentioned in the options, such as Meningitis, Typhoid, and Cholera, are not primarily transmitted through the air but have different modes of transmission.

The correct answer is "He behaves rudely even for menial matters." This answer suggests that the person is not socially balanced because they exhibit rude behavior even for trivial or insignificant issues. This behavior indicates a lack of social awareness and consideration for others, which can be indicative of a state of disease or imbalance.

P.falciparum is the correct answer because it is known to cause the most severe form of malaria. This species of Plasmodium is responsible for the majority of malaria-related deaths worldwide. It can lead to complications such as cerebral malaria, severe anemia, and organ failure. P.ovale, P.malariae, and P.vivax can also cause malaria, but they are generally less severe in comparison to P.falciparum.

Entamoeba histolytica is a protozoan that infects the human intestine. It is responsible for causing amoebic dysentery, a gastrointestinal disease characterized by severe diarrhea, abdominal pain, and dehydration. This parasite is transmitted through the ingestion of contaminated food or water. Once inside the body, Entamoeba histolytica invades the intestinal lining, causing inflammation and tissue destruction. It can also spread to other organs, such as the liver, causing potentially life-threatening complications. Proper sanitation and hygiene practices are essential in preventing the transmission of this protozoan infection.

Tetanus is a bacterial disease caused by the bacterium Clostridium tetani. It is characterized by muscle stiffness and spasms, usually starting in the jaw and neck and spreading to other parts of the body. Meningitis is an inflammation of the protective membranes covering the brain and spinal cord, which can be caused by bacteria, viruses, or other pathogens. Rabies is a viral disease that affects the central nervous system, while smallpox is a viral infection caused by the variola virus. Therefore, the correct answer is Tetanus.

Mother's Milk is a non-antigen because it does not contain any foreign substances that can stimulate an immune response in the body. Antigens are typically proteins or other molecules that are recognized by the immune system as foreign and can trigger an immune response. In contrast, Mother's Milk is a natural substance produced by the mother's body to provide nutrition and immune protection to the baby. It does not contain any pathogens or toxins that would be considered antigens.

When antibodies extracted from another animal are injected into your body, you gain artificial passive acquired immunity. This type of immunity is acquired artificially because it is not naturally produced by your own immune system. It is passive because the antibodies are directly given to you rather than being produced by your own immune system. This type of immunity provides immediate protection against a specific pathogen but does not provide long-term immunity as the antibodies eventually degrade and are eliminated from the body.

Sneezing is one of the means of indirect transmission of a disease. When a person sneezes, they release droplets containing the infectious pathogens into the air. These droplets can then be inhaled by others, leading to the transmission of the disease. Sneezing can be particularly effective in spreading respiratory infections, such as the common cold or influenza, as the droplets can travel a considerable distance and remain suspended in the air for a period of time. Therefore, sneezing can contribute to the spread of diseases from one person to another.
