    Study Notes

    Biology

    • Biology is the study of living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.
    • Key branches of biology include botany (plants), zoology (animals), microbiology (microbes), and genetics (heredity).
    • Cells are the basic units of life, and their structures and functions are vital to understanding biological processes.
    • Organisms exhibit a hierarchy of organization, ranging from molecules to ecosystems.
    • Biological systems are characterized by emergent properties, where the properties of a complex system are not predictable from the properties of its individual components.
    • Evolution is a fundamental concept in biology, explaining the diversity and adaptation of life forms over time.
    • Processes like photosynthesis, respiration, and reproduction are essential for life's continuation.
    • DNA is the hereditary material that carries genetic information from one generation to the next.
    • Biochemistry studies the chemical processes within and related to living organisms.
    • Ecology focuses on the relationships between organisms and their environment.
    • The scientific method is a key tool for biological research, involving observation, hypothesis formulation, experimentation, and analysis.
    • Biological diversity exists on a global scale, with different species adapted to various habitats.

    Chemistry

    • Chemistry is the study of matter and its properties, composition, structure, behavior, and the changes it undergoes.
    • Matter is anything that has mass and occupies space.
    • Elements are the fundamental building blocks of matter, each with a unique atomic structure.
    • Atoms are the smallest units of an element that retain its chemical properties.
    • Elements are organized in the periodic table based on their atomic number and properties.
    • Compounds are formed from the chemical combination of two or more elements.
    • Chemical bonds hold atoms together in molecules and compounds.
    • Chemical reactions involve the rearrangement of atoms to form new substances.
    • States of matter include solid, liquid, and gas, each with unique properties.
    • Solutions are homogeneous mixtures of two or more substances.
    • Acids and bases are substances that affect the pH of a solution.
    • Thermodynamics studies the energy transformations in chemical reactions.
    • Kinetics studies the rates of chemical reactions.
    • Organic chemistry focuses on carbon-containing compounds.
    • Inorganic chemistry deals with non-carbon compounds.
    • Biochemistry is an overlap of biology and chemistry studying chemical processes in living organisms.

    Physics

    • Physics is the study of matter, energy, motion, forces, and their interactions.
    • Fundamental forces of nature are gravity, electromagnetism, strong nuclear force, and weak nuclear force.
    • Classical mechanics deals with the motion of macroscopic objects.
    • Thermodynamics studies heat and energy transfer.
    • Electromagnetism deals with electric and magnetic phenomena.
    • Optics deals with light and its properties.
    • Modern physics includes relativity and quantum mechanics.
    • Relativity describes the universe at high speeds and large scales.
    • Quantum mechanics describes the behavior of matter at the atomic and subatomic levels.
    • Motion involves velocity, acceleration, and forces, which can be understood with equations of motion.
    • Energy exists in various forms (kinetic, potential, thermal, etc.).
    • Energy conservation is a fundamental principle of physics.
    • Waves are disturbances that transfer energy.
    • Light can be considered as both a wave and a particle (photon).
    • Units of measurement ensure consistent and precise description of physical quantities.
    • Physical laws and principles describe the universe's behavior.
    • Atomic models and structure are important concepts to understand the characteristics of elements and their interaction.
