Cell Theory Fundamentals

1. All living things are composed of one or more cells.
2. The cell is the basic unit of life.
3. All cells originate from pre-existing cells.

Types of Cells

Prokaryotic Cells

Simple structure, lack a nucleus, and contain no membrane-bound organelles (e.g., bacteria).

Eukaryotic Cells

Complex structure, possess a nucleus and various organelles (e.g., plant and animal cells).

Cell Organelles: Structure and Function

Organelles Common to Plant and Animal Cells

Cell Membrane

Controls the entry and exit of substances.

Cytoplasm

Jelly-like substance that holds organelles; site of many cellular reactions.

Nucleus

Controls cell activities and holds the cell's DNA.

Nucleolus

Responsible for making ribosomes.

Ribosomes

Sites of protein synthesis (make proteins)

Understanding Feeding and Nutrition

Feeding vs. Nutrition: Key Differences

• Feeding (Eating): Subjective, voluntary, and conscious actions related to consuming food.
• Nutrition (Nourishing): Involuntary, unconscious, and objective processes involving the assimilation of nutrients by the body.

Essential Nutrients: Organic and Inorganic

Nutrients are classified based on whether they contain carbon (C).

Inorganic Nutrients

These nutrients do not contain carbon (C). They are vital for bodily functions.

• Water: Essential for all chemical reactions in the body.
• Mineral Salts: Essential inorganic nutrients needed in small amounts.

Organic Nutrients

These nutrients contain carbon (C). They provide energy and building blocks for the body.

• Carbohydrates: Provide fast

Proximity to Markets, Labour, and Competitors

Proximity to Market

Businesses that produce bulky, heavy, or fragile goods often choose to locate close to their customers so that transportation costs remain low. Service-based businesses may also prefer being near their customers since many services—such as hairdressing or restaurants—are delivered face-to-face.

Proximity to Labour

Firms often look for locations where labour is affordable or where specific skills are available. Labour skills are not evenly spread across regions. For example, some companies in Europe and the USA have moved production to Southeast Asia because wages are lower and labour is readily available.

Proximity to Competitors

Some businesses choose to avoid locating near competitors... Continue reading "Key Factors Influencing Business Location Decisions" »

Chapter 1: The Nature and Significance of Management

Meaning of Management

Management is the process of planning, organizing, staffing, directing, and controlling resources to achieve organizational goals efficiently and effectively.

Characteristics of Management

• Goal-oriented: Aims to achieve specific organizational objectives.
• Pervasive: Required in all types of organizations, at all levels.
• Multidimensional: Involves managing work, people, and operations.
• Continuous Process: A series of ongoing, interrelated functions.
• Group Activity: Involves collective effort to achieve group goals.
• Dynamic Function: Adapts to a constantly changing environment.
• Intangible Force: Its presence is felt through the results it achieves.

Functions of Management

• Planning
• Organizing
• Staffing
• Directing
• Controlling

Objectives

Kinematics: Understanding Motion

Scalars and Vectors in Motion

• Scalars: Quantities possessing magnitude only (e.g., speed, distance, time, mass).

• Vectors: Quantities possessing both magnitude and direction (e.g., velocity, displacement, acceleration, force). These are represented by arrows.

  • Position: Displacement (Vector)

  • Change: Distance (Scalar), Displacement (Vector)

  • Rate: Speed (Scalar), Velocity (Vector)

  • Change in Rate: Acceleration (Vector)

Constant Acceleration Equations

• Variables Used: Final velocity (v), Initial velocity (u), Acceleration (a), Displacement (s), Time (t).

• Key Equations:

  • v = u + at

  • v² = u² + 2as

  • s = &frac12(u+v)t

  • s = ut + &frac12at²

  • s = vt - &frac12at²

Graphing Motion Characteristics

• Displacement-Time (s-t) Graph:
