Introduction to Biology

Study Notes

Biology

Biology is the study of life and living organisms, including their structure, function, growth, origin, evolution, and distribution.
Key branches of biology include botany (plants), zoology (animals), microbiology (microorganisms), genetics (heredity), and ecology (interactions between organisms and their environment).
Fundamental processes in biology include cellular respiration, photosynthesis, metabolism, reproduction, and adaptation.
The cell is the basic unit of life, and all living organisms are composed of one or more cells.
DNA (deoxyribonucleic acid) carries the genetic information that dictates the characteristics of an organism and controls cellular activities.
Evolutionary processes, such as natural selection, drive the adaptation and diversification of life forms over time.
Biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems.
The scientific method is a systematic approach used to investigate biological phenomena and answer biological questions.
Organisms interact within their environment through biological processes, such as trophic levels (food chains), competition, predation, and mutualism.
Major biological systems in organisms include the circulatory, respiratory, digestive, nervous, and endocrine systems.

Physics

Physics is the study of matter, energy, and their interactions.
Fundamental concepts include motion, forces, energy, momentum, and waves.
Classical mechanics deals with the motion of objects and the forces acting upon them.
Thermodynamics describes the relationship between heat, work, and temperature.
Electricity and magnetism study the interaction of charged particles and magnetic fields.
Optics deals with the behavior of light.
Quantum mechanics describes the behavior of matter and energy at the atomic and subatomic levels.
Relativity describes the relationship between space and time, particularly at high speeds and strong gravitational fields.
Physics employs mathematical models and experiments to understand the fundamental laws of the universe.
Key instruments used in physics include telescopes, microscopes, and particle accelerators.

Chemistry

Chemistry is the study of matter and its properties, the changes it undergoes, and the energy associated with these changes.
Matter is anything that has mass and occupies space.
Elements are pure substances consisting of only one type of atom.
Compounds are substances formed from the chemical combination of two or more elements.
Atomic structure describes the composition of atoms, including protons, neutrons, and electrons.
Chemical bonds hold atoms together in molecules or compounds.
Chemical reactions involve the rearrangement of atoms to form new substances.
Stoichiometry deals with the quantitative relationships between reactants and products in a chemical reaction.
Solutions, acids, bases, and salts are important chemical concepts.
Organic chemistry focuses on carbon-containing compounds.

English

English is a West Germanic language that evolved from the languages spoken by the Anglo-Saxon settlers in Britain.
It is one of the most widely spoken languages in the world.
Key elements of English language study include grammar, syntax, vocabulary, and composition.
Grammar focuses on the rules for constructing grammatically correct sentences.
Syntax deals with the arrangement of words and phrases in sentences.
Vocabulary refers to the collection of words available in a language.
Composition skills involve the ability to write clearly, coherently, and effectively.
English literature encompasses a vast body of written works from various periods and genres.
Understanding literary devices, such as imagery, symbolism, and metaphor, enhances appreciation of literature.
Studying different writing styles and historical contexts provides insights into various works.
Analysing texts using various literary theories allows for deeper understanding.
