Biology and Chemistry Overview

Chemical Bonding

• Chemical bonds form when atoms share or transfer electrons to achieve a stable electron configuration
• Ions are charged particles formed when atoms lose or gain electrons
• Conservation of mass dictates that mass is neither created nor destroyed in a chemical reaction

Balancing Chemical Equations

• Skeleton equations show reactants and products without balancing
• Balancing equations ensures equal numbers of atoms on both sides

Types of Chemical Reactions

• Reactions can be classified based on patterns (e.g., synthesis, decomposition, single displacement)

pH and Indicators

• pH indicates acidity or basicity; indicators change color to show pH changes

Chemical Names and Formulas

• Understanding chemical names and formulas is vital to represent compounds

Cell Structure and Function

• Cells are the basic units of life; each contains organelles with specific roles

Cell Specialization

• Cells differentiate into specialized types to perform specific functions

Cell Cycle

• The cell cycle includes stages of growth, DNA replication, and division

Blood Flow Pathway

• Blood flows through the heart and circulatory system, carrying oxygen and nutrients

Photosynthesis

• Photosynthesis is the process where plants convert light energy to chemical energy

Digestive System

• The digestive system breaks down food for nutrient absorption

Blood Cells

• Blood contains various cell types (red blood cells, white blood cells, platelets)

Respiration

• Breathing involves mechanics of inhaling and exhaling air

Plant Tissues

• Plants have specialized tissues for support and transport

Tumours

• Tumours are abnormal growths of cells

Heart Structure

• The heart comprises chambers and valves crucial for blood circulation

Circulatory System

• The circulatory system transports blood and nutrients throughout the body

High Blood Pressure

• High blood pressure (hypertension) can lead to health issues

Exercise and Body Systems

• Exercise impacts different body systems

Light Production

• Light production involves converting energy to light

Light and Optics

• The speed of light is a constant; different mediums affect its speed; Refractive index (RI) calculations relate to light's speed in different mediums. Different types of mirrors and lenses create and modify images.

Optics - Mirrors and Lenses

• Various types of lenses and mirrors (concave, convex) produce different image types (real/virtual, upright/inverted, enlarged/reduced); Using specific rules to accurately draw ray diagrams

The Human Eye

• The human eye focuses images to interpret sight
• Vision problems include nearsightedness and farsightedness

Climate Change

• Gases like carbon dioxide contribute to climate change

Weather Patterns

• Understanding weather patterns involves various atmospheric factors

Atmosphere Layers

• The atmosphere has various layers

Global Warming

• Global warming is a global issue with serious environmental implications

Deforestation

• Deforestation has profound impacts on the environment
