Biology Basics and Principles

Study Notes

Biology

Biology is the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.
Key branches include botany (plants), zoology (animals), microbiology (microorganisms), genetics (heredity), and ecology (interactions between organisms and their environment).
Cell theory posits that all living things are composed of cells, which are the basic units of life.
Organisms exhibit various levels of organization, from molecules to cells, tissues, organs, organ systems, and ultimately, the whole organism.
Characteristics of life include organization, metabolism, growth, adaptation, response to stimuli, reproduction, and homeostasis.
Evolution, driven by natural selection, explains the diversity of life on Earth.
Genetic information is encoded in DNA, which directs protein synthesis.

Physics

Physics is the fundamental science that seeks to understand the fundamental laws governing the universe.
Key concepts include mechanics (motion and forces), thermodynamics (heat and temperature), electromagnetism (electric and magnetic fields), optics (light), and modern physics (relativity and quantum mechanics).
Newton's laws of motion describe the relationship between force and motion.
Energy, in its various forms (kinetic, potential, thermal, etc.), is a fundamental concept in physics.
Conservation laws, such as the conservation of energy and momentum, are crucial principles in physics.
Classical mechanics describes the motion of macroscopic objects, while quantum mechanics deals with the microscopic world.
Relativity, developed by Einstein, revolutionized our understanding of space, time, and gravity.
Measurements, units, and dimensional analysis are essential tools in physics.

Chemistry

Chemistry is the study of matter, its properties, composition, and behavior.
Matter is anything that occupies space and has mass.
Atoms are the fundamental building blocks of matter.
Elements are pure substances consisting of only one type of atom.
Compounds are substances formed by the chemical combination of two or more different elements.
Chemical reactions involve the rearrangement of atoms to form new substances.
States of matter (solid, liquid, gas) differ in their molecular arrangement and properties.
Periodic table organizes elements by their atomic structure and properties.
Chemical bonding describes the forces that hold atoms together in molecules and compounds.
Chemical kinetics studies the rates of chemical reactions.

English

English is a West Germanic language that has evolved over centuries.
Key concepts in English include grammar, vocabulary, and writing.
Grammar governs the structure of sentences and phrases.
Vocabulary encompasses the words used in the language, essential for communication.
Writing involves the use of language in written form, with various styles and purposes.
Literature encompasses a range of written works, including novels, poems, plays, and essays, reflecting human experience.
Rhetorical devices are techniques used to persuade or influence the reader or audience.
Figurative language, including metaphors, similes, and personification, enriches written and spoken communication.
Critical thinking involves analyzing and evaluating information objectively.
Effective communication, both written and oral, requires clarity, conciseness, and engagement with the audience.
Analysis of texts often involves identifying author's purpose, style, and tone.
