Study Notes
Science and Its Branches
- Science is a systematic study of knowledge involving facts and truths.
- "Scientia" translates to "knowledge."
- Divided into three main branches: Natural Science, Social Science, Applied Science.
- Natural Sciences include Physical, Earth, and Biological Sciences.
Natural Sciences
- Focus on the physical and natural world.
- Physical Sciences encompass Physics (study of matter and energy) and Chemistry (composition and reactions of matter).
- Earth Sciences include Geology (Earth's origin and history), Oceanography (study of oceans), Meteorology (atmospheric phenomena), and Astronomy (universe beyond Earth).
Life Sciences (Biology)
- Botany (study of plants), Zoology (animal life), Genetics (heredity), and Medicine (healthcare).
- Multiple interdisciplinary fields exist, such as Biochemistry (Biology + Chemistry) and Astrophysics (Astronomy + Physics).
Theories of the Origin of Life
- Various theories attempt to explain how life began on Earth.
- Major theories include: Theory of Special Creation, Theory of Catastrophism, Theory of Panspermia, Theory of Chemical Evolution, Theory of Spontaneous Generation, and Theory of Evolution.
Theory of Special Creation
- Proposes that all forms of life were created by a divine entity.
- Seen in many religious texts.
- Lacks scientific evidence.
Theory of Catastrophism
- Suggests multiple creations of life by God after catastrophic events on Earth.
- Promoted by scientists such as Georges Cuvier.
Theory of Panspermia
- Life arrived from other celestial bodies via meteorites or spores.
- Lacked supporting evidence, leading to its dismissal.
Theory of Chemical Evolution
- Origin of life resulted from a gradual chemical process approximately 3.8 billion years ago.
- Developed independently by A.I. Oparin and J.B.S. Haldane.
Theory of Spontaneous Generation (Abiogenesis)
- Belief that life arose from non-living matter.
- Notable proponents included Aristotle.
- Disproved through experiments by Redi, Spallanzani, and Pasteur.
Theory of Evolution
- Spearheaded by Charles Darwin, focusing on natural selection.
- Key facts include overproduction of offspring and variation among individuals.
- Fitness leads to survival and reproduction of better-adapted progeny.
Characteristics of Living vs. Non-Living Things
- Living things are defined as anything that is or has ever been alive.
- Non-living things are defined as those that have never been alive.
Differences Between Plants and Animals
- Plants are anchored and immobile, can make their own food via photosynthesis, and release oxygen.
- Animals are typically mobile, rely on plants or other animals for food, and release carbon dioxide.
- Plant cells have rigid cell walls; animal cells lack these and have different structures.
- Animals possess advanced sensory and nervous systems, whereas plants have limited sensory abilities.
