    Another name of Vitamin B2 is (c) Riboflavin. Riboflavin is a water-soluble vitamin essential for various bodily functions, including energy production, metabolism, and maintaining healthy skin, eyes, and nervous system. It plays a crucial role in converting carbohydrates into energy and acts as an antioxidant, protecting cells from damage caused by free radicals. Riboflavin is commonly found in foods such as dairy products, meats, leafy green vegetables, and enriched cereals. Deficiency in riboflavin can lead to symptoms such as skin disorders, inflammation of the mouth and tongue, and decreased red blood cell count.

    The disease of sickle cell anemia is caused due to the abnormality of (b) Red blood cell. It is a genetic disorder characterized by the presence of abnormal hemoglobin, specifically hemoglobin S. This mutation causes red blood cells to assume a rigid, sickle-like shape under certain conditions, leading to blockages in blood vessels, reduced oxygen delivery to tissues, and various complications such as pain crises, organ damage, and anemia. Unlike white blood cells (a), platelets (c), or blood plasma composition (d), which play essential roles in immune response, clotting, and maintaining blood volume, sickle cell anemia primarily affects the structure and function of red blood cells.

  3. The infectious stage of malaria is (d) Sporozoite. Sporozoites are the form of the malaria parasite transmitted to humans through the bite of infected mosquitoes. When an infected mosquito bites a person, it injects sporozoites into the bloodstream. From there, sporozoites travel to the liver, whereRead more

    The infectious stage of malaria is (d) Sporozoite. Sporozoites are the form of the malaria parasite transmitted to humans through the bite of infected mosquitoes. When an infected mosquito bites a person, it injects sporozoites into the bloodstream. From there, sporozoites travel to the liver, where they invade liver cells and multiply, initiating the infection cycle. After replication in the liver, sporozoites develop into merozoites, which are released into the bloodstream, infecting red blood cells and causing symptoms of malaria. Thus, while merozoites are responsible for the symptomatic phase, sporozoites initiate the infection by entering the host’s bloodstream.

    The fungal disease among the options is (c) Ringworm. Powdery mildew, typically affecting plants, is caused by fungal pathogens. Eczema, a skin condition, results from various factors such as genetics and environmental triggers, not fungi. Elephantiasis, caused by parasitic worms transmitted by mosquitoes, isn’t fungal. Ringworm, contrary to its name, is a fungal infection of the skin or scalp. It’s characterized by circular, red, scaly patches that resemble a ring, caused by dermatophyte fungi. Proper antifungal treatment is essential to manage and resolve ringworm infections effectively.

    Chickenpox is caused by a virus, specifically the varicella-zoster virus (VZV). This virus belongs to the herpesvirus family. It’s highly contagious and spreads through respiratory droplets or direct contact with the rash of an infected person. Variola virus, associated with smallpox, is not responsible for chickenpox. Streptococcus bacteria cause various infections but not chickenpox. Vibrio cholerae causes cholera, a bacterial infection characterized by severe diarrhea. Understanding the viral nature of chickenpox is crucial for developing effective prevention strategies and treatments against this common childhood illness.
