This doc explains two key ways organisms share traits: Vertical Similarities: From family trees!

This doc breaks down biology’s essentials: What’s “alive”? Cells, metabolism, growth. Views: Human-focused vs. nature-centered. Species Rule: Fertile offspring only (horses + donkeys ≠ species). Classifying Life: Naming (Solanum tuberosum = potato ) and grouping (Kingdom→Species). Modern Tools: DNA, evolution > just looks.

This document breaks down how scientists organize Earth’s incredible variety of life. You’ll learn: Biodiversity’s scale: Over 1.7 million species exist (and counting!), vital for medicine, farming, and more. Classification basics: How life is sorted into groups (like Kingdom → Species) using taxonomy, with a fun mnemonic to remember the order. Scientific naming: Why potatoes are called Solanum tuberosum (thank Linnaeus and his Latin-based system!). What defines “life”: T...

This document compares two ways to look at nature in biology: Bio-Centric View: All living things matter, not just humans. It focuses on protecting nature, understanding how life connects, and keeping Earth’s diversity alive. Anthropocentric View: Values nature based on how it helps humans (like food, medicine, or research). It drives progress but sometimes puts human needs above nature.

This presentation delves into the fascinating world of nucleic acids, the molecules responsible for storing and transmitting genetic information. It covers the two main types of nucleic acids: DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid), and explains how they work together to carry out the processes of replication, transcription, and translation. You’ll learn about the structure of nucleic acids, made up of nucleotides, and how these sequences determine the genetic code that directs...

This presentation explores the crucial role of proteins in the body as the fundamental building blocks for growth, repair, and function. It covers how proteins are made up of amino acids, and how they are vital for constructing muscles, enzymes, hormones, and other important molecules. The presentation will also explain how proteins help in tissue repair, immune response, and oxygen transport through hemoglobin. You’ll learn about the different types of proteins, including structural proteins ...

This presentation dives into the world of carbohydrates, the body's primary source of energy. You'll learn about the different types of carbs, including simple sugars, complex starches, and dietary fiber, and how they impact your metabolism. The presentation will also cover how carbs are broken down into glucose, stored as glycogen, and used by the body for immediate energy. Additionally, we'll explore the role of insulin in regulating blood sugar levels and discuss the importance of ba...

This presentation explores the essential role of lipids in the human body. It covers the structure and types of lipids, including fats, oils, phospholipids, and sterols. The presentation explains how lipids function, such as energy storage, cell membrane structure, and hormone production. It also highlights their importance in maintaining overall health, including their impact on metabolism, heart health, and the regulation of body temperature. By the end, the audience will understand the crucia...

The document introduces the Social 20 course and explores the key issue: Should we embrace nationalism? It defines nationalism from various perspectives and explains how it shapes individual and collective identity. It breaks down types of nationalism (ethnic, civic, linguistic, geographic, etc.) and emphasizes critical thinking and the inquiry method for exploring complex social issues. It also distinguishes between a nation and a country, and highlights terms like patriotism, multiculturalism,...
