Q92. The spread of cancer cells from the primary site of origin to other parts of the body is termed:
Explanation
Metastasis is the process by which cancer cells break away from the primary tumor and travel through the blood or lymphatic system to form new tumors in other parts of the body. This spread is what makes cancer a particularly dangerous and life-threatening disease. Once a cancer has metastasized, it is often more difficult to treat and requires systemic therapies like chemotherapy rather than localized surgery.

Monosaccharides are the simplest sugars and cannot be further hydrolyzed into smaller units. Glucose and fructose are both examples of monosaccharides that are naturally found in various foods. Sucrose, on the other hand, is a disaccharide formed by the chemical bonding of one glucose molecule and one fructose molecule. Understanding these classifications is important for grasping how carbohydrates are digested and metabolized.

Q97. The deficiency of which vitamin is historically known to affect sailors on long voyages, causing swollen and bleeding gums?

Scurvy is a disease resulting from a severe deficiency of Vitamin C, which is essential for the production of collagen. Historically, it was common among sailors who lacked access to fresh fruits and vegetables during long sea voyages. Symptoms include fatigue, swollen and bleeding gums, and joint pain. The discovery that citrus fruits could prevent and cure scurvy was a major breakthrough in nutritional science.

Q99. A balanced diet should provide adequate micronutrients. Which of the following statements about micronutrients is correct?
Explanation
Micronutrients, which include various vitamins and minerals, are required by the body in very small amounts. Although they do not provide energy themselves, they are essential for regulating a wide range of metabolic processes, including growth, immune function, and brain development. Because the body cannot produce most micronutrients, they must be obtained through a varied and balanced diet for optimal health.
