5th Class Sample Quiz

Communicable diseases are the correct answer because they are illnesses that can be transmitted from one person to another through various means such as direct contact, airborne droplets, or contaminated objects. These diseases include common infections like the flu, colds, and COVID-19, as well as more serious conditions like tuberculosis and HIV/AIDS. Non-communicable diseases, on the other hand, are not contagious and cannot be spread between individuals. Infectious diseases can be used interchangeably with communicable diseases, as they refer to the same concept of illnesses that can be transmitted from person to person.

Vitamin D is obtained from sunlight. When our skin is exposed to sunlight, it produces a form of cholesterol that is converted into vitamin D by the body. This vitamin is essential for the absorption of calcium and phosphorus, which are important for bone health. It also plays a role in supporting the immune system and regulating mood. While other vitamins like B and C are important for various bodily functions, they are not specifically obtained from sunlight. Therefore, the correct answer is Vitamin D.

The term "disease" refers to an abnormal condition in the body that impairs its normal functioning. It is a broad term that encompasses a wide range of illnesses, infections, and disorders that can affect various systems and organs in the body. Hunger and being energetic are not considered abnormal conditions in the body, so they are not the correct answer. "None of these" is not the correct answer either, as the given options do not cover all possible conditions. Therefore, the correct answer is "Disease."

Water is helpful for maintaining body temperature because it has a high heat capacity, which means it can absorb and release heat without changing its own temperature significantly. This helps regulate body temperature and prevent overheating or hypothermia. Water also helps in digestion by breaking down food and facilitating the absorption of nutrients. Additionally, it aids in excretion by flushing out waste products through urine and sweat. Therefore, all of these statements are true and water is helpful for maintaining body temperature, aiding digestion, and facilitating excretion.

Cholera is caused by the consumption of contaminated food and water. The bacteria responsible for cholera, Vibrio cholerae, is commonly found in water sources that have been contaminated with fecal matter. When a person ingests food or water that has been contaminated with this bacteria, they become infected and can develop symptoms of cholera, such as severe diarrhea and dehydration. Therefore, taking contaminated food and water is the main mode of transmission for cholera.

ORS (Oral Rehydration Solution) is a solution used to treat dehydration caused by vomiting and diarrhea. When a person suffers from vomiting and motions, their body loses essential fluids and electrolytes. ORS helps to replace these lost fluids and electrolytes, preventing dehydration and helping the body recover. It contains a balanced amount of salts, sugar, and water, which are easily absorbed by the body. Therefore, ORS is an effective solution for treating vomiting and motions.

Ringworm is a skin disease caused by a fungal infection. It is characterized by a red, circular rash that may be itchy and scaly. It can affect various parts of the body, including the scalp, feet, groin, and nails. Ringworm is highly contagious and can be spread through direct contact with an infected person or animal, or by touching contaminated surfaces. Treatment typically involves antifungal medications applied topically or taken orally, depending on the severity of the infection. Proper hygiene and avoiding contact with infected individuals or animals can help prevent the spread of ringworm.

If a person does not take a balanced diet for a long period of time, they are likely to develop malnutrition. Malnutrition refers to a condition where the body does not receive the necessary nutrients, vitamins, and minerals needed for proper functioning. This can lead to various health problems and deficiencies, affecting the overall well-being of the individual. Therefore, the correct answer is "Mal Nutrition Condition."

Lactic bacteria help us by changing milk to curd. Lactic bacteria are responsible for the fermentation process that occurs in milk, which converts lactose (milk sugar) into lactic acid. This acidification causes the milk to curdle and form curd. Curd is a dairy product that is widely consumed and used in various culinary preparations. The action of lactic bacteria in converting milk to curd also contributes to the development of a tangy flavor and the thickening of the milk.

Yeast, which is a type of fungi, is commonly used in bakeries. It is used as a leavening agent in bread making, where it helps the dough rise by producing carbon dioxide gas through fermentation. This process gives bread its fluffy texture and helps it to become light and airy. Therefore, yeast is an essential ingredient in baking and is primarily used in bakeries.

Iron is a mineral that is essential for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Without enough iron, the body cannot produce an adequate amount of red blood cells, leading to a condition called iron deficiency anemia. Therefore, iron is needed by the body to make blood.

Fibre food or roughages are known for their ability to clean the digestive system. They promote healthy digestion by adding bulk to the stool, preventing constipation, and promoting regular bowel movements. In the stomach, fibre helps to break down food particles and move them along the digestive tract. In the small intestine, it aids in the absorption of nutrients and prevents the build-up of waste. In the large intestine, fibre adds bulk to the stool and helps in its elimination. Therefore, fibre food or roughages clean all three parts of the digestive system - the stomach, small intestine, and large intestine.

Typhoid is caused by bacteria. Bacterial infection occurs when the Salmonella typhi bacteria enters the body through contaminated food or water. Once inside, the bacteria multiply in the intestines and can spread to other parts of the body through the bloodstream. This leads to symptoms such as high fever, abdominal pain, weakness, and diarrhea. Prompt treatment with antibiotics is necessary to prevent complications and further spread of the infection.

Tuberculosis is caused by the bacteria Mycobacterium tuberculosis, which is primarily transmitted through the air. When an infected individual coughs or sneezes, they release tiny droplets containing the bacteria into the air, which can then be inhaled by others. This mode of transmission is known as airborne transmission. While contaminated water or food can transmit other diseases, tuberculosis is specifically transmitted through the respiratory route, making air the correct answer.

Vitamin C is used for the formation of blood cells. It plays a crucial role in the production of collagen, a protein that helps in the formation of blood vessels, skin, and connective tissues. Additionally, vitamin C aids in the absorption of iron, which is essential for the production of red blood cells. Therefore, a deficiency in vitamin C can lead to anemia and impaired blood cell formation.
