MPPSC Prelims and Mains Notes, MPPCS Test Series
Points to Remember: Find the least common multiple (LCM) of 8, 10, and 12. Identify the largest three-digit multiple of the LCM. Introduction: This question requires a mathematical approach to find the largest three-digit number divisible by 8, 10, and 12. This involves determining the least common multiple (LCM) of these three numbers and then … Read more
Points to Remember: Arithmetic mean is the average of a set of numbers. It’s calculated by summing all the numbers and dividing by the count of numbers. Sensitive to outliers (extreme values). Introduction: The arithmetic mean, commonly known as the average, is a fundamental statistical measure used to represent the central tendency of a dataset. … Read more
Points to Remember: The cell cycle is a series of events that lead to cell growth and division. It consists of interphase and the mitotic (M) phase. Regulation of the cell cycle is crucial for healthy growth and development. Errors in cell cycle regulation can lead to cancer. Introduction: The cell cycle is a fundamental … Read more
Points to Remember: Cache memory is a type of high-speed memory that stores frequently accessed data. It acts as a buffer between the CPU and main memory (RAM). Different levels of cache exist (L1, L2, L3), each with varying speeds and sizes. Cache improves system performance by reducing access time to data. Introduction: Cache memory … Read more
Points to Remember: E-government focuses on the online delivery of government services to citizens and businesses. E-governance encompasses a broader scope, including the use of ICTs to improve government processes, decision-making, and citizen participation. The key difference lies in the focus: service delivery versus overall governance improvement. Introduction: The terms “e-government” and “e-governance” are often … Read more
Points to Remember: The octet rule explains the stability of atoms. Atoms achieve stability by gaining, losing, or sharing electrons to obtain eight electrons in their valence shell. Exceptions to the octet rule exist. Introduction: The octet rule, proposed independently by Gilbert N. Lewis and Walther Kossel in the early 20th century, is a fundamental … Read more
Points to Remember: Aqua regia’s composition and properties. Its historical significance and modern applications. Safety precautions associated with its handling. Introduction: Aqua regia, Latin for “royal water,” is a highly corrosive, fuming mixture of concentrated nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. It is known for its unique ability to … Read more
Points to Remember: Location and size of the pituitary gland. Its two main lobes: anterior and posterior, and their respective functions. Hormones produced by each lobe and their effects on the body. Regulation of pituitary gland function. Clinical significance of pituitary disorders. Introduction: The pituitary gland, also known as the hypophysis, is a small, pea-sized … Read more
Points to Remember: Inertia is a fundamental property of matter. It resists changes in motion. Newton’s First Law of Motion defines inertia. Inertia is related to mass. Overcoming inertia requires force. Introduction: Inertia is a fundamental concept in physics, describing an object’s resistance to changes in its state of motion. It’s not a force itself, … Read more
Points to Remember: Cartesian sign convention is a set of rules for assigning signs to distances in ray optics calculations. It simplifies calculations by consistently handling distances and their directions. The convention is based on a coordinate system with the origin at the optical center of the lens or mirror. Introduction: Ray optics, also known … Read more
