    The contraceptive pills available in the market typically contain (d) Steroid Hormones. Specifically, they contain synthetic versions of estrogen and/or progestin, which are types of steroid hormones. These hormones work by regulating the menstrual cycle and preventing ovulation, thus inhibiting pregnancy. Some contraceptive pills contain only progestin and are referred to as mini-pills. These hormones are formulated to mimic the natural hormones produced by the ovaries. Unlike antibiotics (c) or herbicides (b), which have different mechanisms of action, contraceptive pills utilize steroid hormones to provide effective contraception when taken as directed.

  2. The BCG vaccine is typically given to newborns, so the correct answer is (c) Newborn. It is administered shortly after birth, usually within the first few days to weeks of life. This timing is optimal for providing protection against tuberculosis (TB) in infancy, as newborns are at increased risk ofRead more

    The BCG vaccine is typically given to newborns, so the correct answer is (c) Newborn. It is administered shortly after birth, usually within the first few days to weeks of life. This timing is optimal for providing protection against tuberculosis (TB) in infancy, as newborns are at increased risk of severe forms of TB if exposed to the bacterium. The BCG vaccine helps prevent severe forms of TB, such as TB meningitis and miliary TB, in young children. In some countries, the BCG vaccine may also be given to older children and adults at high risk of TB infection or complications.

    Rabies is a (b) Viral disease caused by the rabies virus, a member of the Rhabdoviridae family. It affects the central nervous system, leading to severe neurological symptoms. Rabies is typically transmitted through the bite of an infected animal, with dogs being the most common transmitter worldwide. Once symptoms appear, the disease is almost always fatal. Early symptoms may include fever and tingling at the site of the bite, while later stages may manifest as hydrophobia (fear of water), hallucinations, paralysis, and eventually coma. Immediate medical treatment, including post-exposure prophylaxis, is essential to prevent rabies infection from progressing.

    Plague primarily spreads through (a) Bacteria. It is caused by the bacterium Yersinia pestis. Transmission occurs through the bite of infected fleas, primarily from rodents like rats, squirrels, and prairie dogs. Additionally, handling infected animals or inhaling respiratory droplets from infected individuals, particularly in cases of pneumonic plague, can also lead to transmission. Plague is not caused by protozoa (b) or viruses (c). While certain diseases caused by protozoa or viruses can spread similarly through vectors or respiratory droplets, plague specifically involves the bacterium Yersinia pestis as its causative agent.

    The disease caused by fungus is (b) Dermatitis. Dermatitis refers to inflammation of the skin, which can result from fungal infections like ringworm (tinea) or candidiasis. These infections are caused by different types of fungi and can lead to various symptoms such as redness, itching, and rashes on the skin. Polio (a) is caused by a virus, specifically the poliovirus, while Cholera (c) is caused by the bacterium Vibrio cholerae. Therefore, the correct answer is (b) Dermatitis, as it is the only option caused by a fungal infection.
