Fundamental Economic Concepts: Scarcity, Money, and Systems
What is Economics?
Economics is fundamentally about choices. We face unlimited wants but possess limited resources (such as money, time, and materials). Economics studies how people utilize what they have to obtain what they need or desire.
Needs Versus Wants
- Needs: Essential for survival (e.g., food, water, clothing).
- Wants: Desirable but not necessary for survival (e.g., an iPhone, a car, a vacation).
Scarcity and the Economic Problem
Scarcity means there are not enough resources for everyone. Because
Cell Division and Species Variation: Genetics Fundamentals
Reproductive Strategies
Reproductive Strategies
- Asexual Reproduction: A single parent organism produces offspring by making genetically identical copies of itself.
- Sexual Reproduction: Two parent organisms combine genetic material to produce similar but genetically unique offspring.
Asexual Reproduction
- Requires less energy.
- Needs only one parent.
- All organisms are able to reproduce, passing on 100% of their genetic material.
- One organism may begin an entire population.
- Offspring are exact replicas of the
Indus Valley Civilization: Architecture & Urban Planning
(c. 2600 BCE – 1900 BCE)
The Indus Valley Civilization is one of the world’s earliest and most advanced urban civilizations. It developed along the Indus River and its tributaries in present-day India and Pakistan. Architecturally, it is known for scientific town planning, standardized construction, and advanced civic infrastructure.

Black Money in India
Black money refers to income or wealth that is earned through illegal means or is unreported and untaxed. In India, black money is a significant issue, often linked to corruption, tax evasion, and illicit activities. It is typically held in cash or offshore accounts to avoid detection.
Sources of Black Money
- Tax Evasion: Unreported income or wealth, often in cash, to avoid paying taxes.
- Corruption: Bribes, kickbacks, and other forms of corruption.
- Illicit Activities: Income from
Strategic Supply Chain Management and Operations
What is Supply Chain Management?
Supply Chain Management (SCM) refers to the process of planning, implementing, and controlling all activities involved in the sourcing of raw materials, production, handling, storage, and distribution of finished goods to the final customer. It integrates suppliers, manufacturers, warehouses, transporters, retailers, and customers into one seamless system to ensure the right product reaches the right customer at the right time and at the right cost.

I can’t help with “copy-ready” answers to paste in an exam. But I can give you a complete, high-score revision pack + model practice responses that match your lecture slides (so you can write them in your own words fast).
What the final focuses on (high priority)
Your Week 10 review slide says the finals cover three CLO areas: Motivational Theories, Competency-based Frameworks, and Staff Appraisals. Also, the syllabus states the Final Exam is closed book and covers CLOs 1, 4 and 5.

Sedimentary Petrology: Transport and Lithification
Recap of Sedimentary Rock Formation
UNIT I (b): Transportation, Deposition & Lithification (Sedimentary Petrology – CC VI)
Background Concepts
Before understanding transportation and deposition, we must recall what happens before sediments move:
Sedimentary Rocks
- Formed by the accumulation, deposition, and lithification of sediments.
- They cover approximately 75% of the Earth’s surface.
Weathering
Weathering is the breakdown of rocks in situ.
- Physical weathering: Mechanical disintegration with no
Digital Forensics: Principles, Tools, and Procedures
Computer Forensic Services
Computer forensic services involve the professional application of scientific investigation techniques to identify, preserve, extract, and analyze data from digital devices. These services are used to transform raw digital data into “legal evidence” that can be presented in a court of law. For your SPPU exam, remember that these services aren’t just about finding files; they focus on maintaining the integrity of data and a strict chain of custody.
Typical services include:

Relational Database Design and Normalization
The relational model stores data in tables (relations), where rows represent tuples and columns represent attributes.
- Key components: Tables, attributes, tuples, and constraints (PK, FK, UNIQUE, NOT NULL).
- Mapping ER to Relational: Entity becomes a table, 1:many uses a foreign key (FK) on the many side, many:many requires a junction table, and multivalued attributes move to separate tables.
Functional Dependency (FD): X → Y means X uniquely determines Y.
