11a. Plant, Animal, and Microbial Cells
Plant and animal cells are eukaryotic, featuring a true nucleus and membrane-bound organelles, whereas most microbial (bacterial) cells are prokaryotic, lacking a true nucleus and typical organelles.
Plant cells possess a cellulose cell wall, chloroplasts, a large central vacuole, and plasmodesmata. Animal cells lack a cell wall and chloroplasts but contain lysosomes, centrioles, and a prominent extracellular matrix. Bacterial cells have a peptidoglycan cell

Linux File System Architecture
The Linux file system is a hierarchical structure that organizes data on storage devices. Unlike Windows, which uses drive letters (C:, D:), Linux uses a single, unified structure starting from the root directory (/).
1. Files, Inodes, and Structure
A. Linux Files: Everything is a File
In Linux, everything is treated as a file, which simplifies system interaction. This includes:
- Regular Files: Text files, executable programs, images, documents.
- Directories: Special files
Elder Maltreatment Prevention and Retirement Psychology
Elder Maltreatment and Caregiver Stress
Maltreatment, stress, and a sense of burden are strong predictors of elder abuse by caregivers. The reasons why carers abuse have been linked to factors such as social isolation, failing health, and poor interpersonal relationships.
Referrals for Elderly at Risk of Maltreatment
The referrals for the elderly at risk of or who have endured maltreatment include:
- They must keep in touch with old friends and neighbors even during a change of address.
- They must participate

Molecular Cloning: Competent Cells, Ligation, and PCR
Preparation of Competent Cells
Aim: To prepare E. coli TOP10 cells capable of taking up foreign DNA (plasmid) using the calcium chloride method.
Core Principle
Calcium Chloride (CaCl₂) neutralizes the negative charges on the cell membrane (phospholipids) and the DNA backbone, reducing electrostatic repulsion. This, followed by a heat shock, creates transient pores for DNA entry.
Key Terms
- Competence: A cell’s ability to take up extracellular DNA.
- Transformation: The process of importing foreign DNA.
WACC Calculation and Capital Structure: Optimal Leverage & Pecking Order
Weighted Average Cost of Capital (WACC)
WACC = the weighted average cost of the financial resources used by a company or project after taxes. It represents what it costs the company to obtain financing. It combines the cost of debt and the cost of equity (what shareholders require), weighted according to the proportion that debt and equity have in the capital structure.
CAPM Assumptions
- Perfect markets (perfect competition, free information for all investors, and no transaction costs).
- Homogeneous

Incident Response and BCP Improvements for Remote Projects
Scenario 1: Personal Device Risks
Question 1: Dangers of personal devices
Personal devices often lack enterprise-grade security tools. They are more likely to be unpatched, outdated, or unmonitored and provide no centralized control for security teams. Using personal devices increases the attack surface, especially when accessing critical infrastructure.
Question 2: How could this malware have been detected?
Answer: Endpoint Detection and Response (EDR) tools would have flagged anomalous behavior such

Fundamentals of Computer Graphics
What is Computer Graphics?
Computer graphics is the field of computer science focused on creating, manipulating, and storing images and visual content using computers. It is a crucial discipline because it enables the visualization of complex data, enhances user interfaces, and drives innovations in entertainment, science, and design.
Importance and Applications
- Data Visualization: Computer graphics simplifies and visualizes complex data for easier understanding, analysis,
