Study Notes
Biology
- Definition: The study of living organisms and life processes.
-
Key Branches:
- Zoology: Study of animals.
- Botany: Study of plants.
- Microbiology: Study of microorganisms.
-
Cell Theory:
- All living things are composed of cells.
- The cell is the basic unit of life.
- All cells arise from pre-existing cells.
-
Genetics: Study of heredity and genetic variation.
- DNA: Carrier of genetic information.
- Mitosis: Process of cell division for growth and repair.
- Meiosis: Process of cell division for reproduction.
- Evolution: Theory explaining the diversity of life through natural selection and adaptation.
Physics
- Definition: The study of matter, energy, and the interactions between them.
-
Key Concepts:
- Force: An interaction that changes the state of motion of an object.
-
Energy: The ability to do work.
- Kinetic Energy: Energy of motion.
- Potential Energy: Stored energy based on position.
-
Laws of Motion (Newton's Laws):
- An object at rest stays at rest; an object in motion stays in motion unless acted upon by a force.
- Force equals mass times acceleration (F=ma).
- For every action, there is an equal and opposite reaction.
-
Thermodynamics: Study of heat, energy, and work.
- First Law: Energy cannot be created or destroyed, only transformed.
- Second Law: Entropy of an isolated system never decreases.
Chemistry
- Definition: The study of matter, its properties, and the changes it undergoes.
-
Key Concepts:
-
Atoms and Molecules:
- Atoms: Basic building blocks of matter.
- Molecules: Two or more atoms bonded together.
-
Chemical Bonding:
- Ionic Bonds: Transfer of electrons between atoms.
- Covalent Bonds: Sharing of electrons between atoms.
-
Chemical Reactions:
- Reactants: Substances that undergo change.
- Products: Substances formed after the reaction.
- Types include synthesis, decomposition, single replacement, and double replacement.
-
Atoms and Molecules:
-
States of Matter:
- Solid, liquid, gas, and plasma.
- pH Scale: Measures acidity or alkalinity of a solution (0-14 scale; 7 is neutral).
Interconnections
- All three sciences interact:
- Biological processes depend on physical and chemical principles.
- Understanding chemical reactions helps explain biological functions.
- Physics principles are crucial for many biological processes such as movement and energy transfer.
