Cancer vs stem //// Both normal stem cells and cancer stem cells share the ability to self-renew through asymmetric division, allowing one daughter cell to remain a stem cell while the other differentiates. They both generate heterogeneous populations of mature cells: normal stem cells produce tissue-specific cell types, while CSCs produce diverse tumor cells. Both rely on similar regulatory signaling pathways such as Wnt, Notch, and Hedgehog, but these pathways are tightly controlled in normal
Non-discrimination in services under international trade law, specifically within the World Trade Organization (WTO), is governed by two key principles:
- *Most-Favored-Nation (MFN) Treatment*: Countries must treat all WTO members equally, meaning any favorable treatment given to one member must be extended to all others.
- *National Treatment*: Foreign services and service providers must be treated no less favorably than domestic ones once they've entered the market.
These principles aim to ensure
Physical vs Human Geography
Physical = natural systems & processes (weather, climate, landforms). Human = culture, population, cities.
Atmospheric Structure
Pressure & density ↓ with height.
Temperature pattern: Troposphere ↓, Stratosphere ↑, Mesosphere ↓, Thermosphere ↑.
Inversion: temp increases with height in a layer.
Temp ↑ → molecules move faster.
Maps & Coordinates
Global coordinate system = grid for locating places (latitude/longitude).
Latitude → day length;
Log-based recovery is a mechanism used in DBMS to restore the database to a consistent state after a system crash or failure. The system maintains a log file stored on stable storage, recording every transaction's operations before applying them to the database. Each log entry contains the transaction ID, data item name, old value, and new value. Using these logs, the DBMS can reconstruct the database by either undoing incomplete transactions or redoing completed ones.
Two major operations are used...

## Economic Principles Overview:
### 1. Opportunity Cost:
- *Definition*: The value of the next best alternative foregone when making a decision.
- *Example*: If you spend ₹100 on a movie ticket, the opportunity cost is what else you could have bought with that ₹100.
### 2. Marginal Principle:
- *Definition*: Decisions are made based on the additional (marginal) benefits and costs of an action.
- *Example*: Produce more units of a product until marginal revenue equals marginal cost.
### 3. Incremental
