Heart attacks are primarily caused by (c) Lack of blood supply to the heart. This occurs when the coronary arteries that supply blood to the heart muscle become narrowed or blocked, often due to the buildup of plaque. This deprives the heart muscle of oxygen and nutrients, leading to tissue damage and potentially a heart attack.
Heart attacks, medically known as myocardial infarctions, are typically triggered by the sudden rupture of a plaque within the coronary artery, leading to the formation of a blood clot that obstructs blood flow. This interruption of blood supply causes damage or death to part of the heart muscle, resulting in a heart attack.
Carbohydrates are stored in plants and animals primarily in the form of (b) Starch and Glycogen. Starch serves as the main storage carbohydrate in plants, found in structures such as roots, tubers, and seeds.

Carbohydrates are stored in plants and animals primarily in the form of (b) Starch and Glycogen. Starch serves as the main storage carbohydrate in plants, found in structures such as roots, tubers, and seeds. Glycogen, on the other hand, is the main storage carbohydrate in animals, stored primarily in the liver and muscles. While glucose is a simple sugar and a component of both starch and glycogen, cellulose is a structural carbohydrate found in plant cell walls and is not used for energy storage in either plants or animals.
The white color of milk primarily arises from the scattering of light by various components within it.

While milk contains several compounds, the main contributor to its white appearance is (c) Carotene. Carotene is a pigment found in the fat globules of milk, contributing to its slightly yellowish-white color. However, the concentration of carotene in milk is relatively low compared to other sources, such as carrots.

Multi drug therapy (MDT) is for the infection of Leprosy. MDT involves the simultaneous use of multiple antibiotics to treat leprosy effectively. This approach targets different strains of the bacterium Mycobacterium leprae, reducing the risk of drug resistance development. MDT typically includes drugs such as dapsone, rifampicin, and clofazimine, administered over several months to years depending on the severity of the infection. By using a combination of antibiotics, MDT helps to improve treatment outcomes, reduce the duration of therapy, prevent relapse, and minimize the spread of leprosy in affected populations.
Vitamin D is (b) Calciferol. Calciferol, commonly known as vitamin D, is a fat-soluble vitamin essential for various bodily functions.

Vitamin D is (b) Calciferol. Calciferol, commonly known as vitamin D, is a fat-soluble vitamin essential for various bodily functions. It plays a crucial role in calcium absorption, promoting healthy bones and teeth, and supporting immune function. Unlike water-soluble vitamins like ascorbic acid (a) (vitamin C) and folic acid (c), which dissolve in water and are not stored in the body, vitamin D is stored in fat cells and released when needed. It is distinct from retinol (d), which refers to vitamin A. Vitamin D can be obtained through sunlight exposure, dietary sources, or supplements.
The vitamin that is soluble in water is (b) Vitamin B. Water-soluble vitamins dissolve in water and are not stored in the body to the same extent as fat-soluble vitamins. Vitamin B includes various B vitamins such as B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine)Read more
The vitamin that is soluble in water is (b) Vitamin B. Water-soluble vitamins dissolve in water and are not stored in the body to the same extent as fat-soluble vitamins. Vitamin B includes various B vitamins such as B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). These vitamins play crucial roles in energy metabolism, nervous system function, cell metabolism, and the formation of red blood cells. Excess water-soluble vitamins are usually excreted in urine, so regular intake through diet or supplementation is essential.
The daily energy requirement of a hardworking man varies based on factors such as age, weight, height, physical activity level, and metabolism.

The daily energy requirement of a hardworking man varies based on factors such as age, weight, height, physical activity level, and metabolism. However, a rough estimate for a hardworking individual engaged in strenuous activities might range between 3500 Kcal to 4000 Kcal per day. This higher energy requirement is necessary to fuel the increased metabolic demands associated with vigorous physical work. It’s crucial for such individuals to consume a balanced diet rich in carbohydrates, proteins, healthy fats, vitamins, and minerals to meet their energy needs and support overall health and performance. Regular monitoring and adjustment of dietary intake based on activity levels and energy expenditure are recommended to maintain optimal health and performance.
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 anRead more
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.
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.

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.
