1. Hypothesis: A proposed explanation for a phenomenon, which can be tested through experimentation.
- Example: The scientist formulated a hypothesis to explain the relationship between temperature and plant growth.
2. Photosynthesis: The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
- Example: Photosynthesis is crucial for the production of oxygen and the conversion of carbon dioxide into organic compounds.
3. Mitosis: A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
- Example: Mitosis plays a key role in growth, development, and repair of multicellular organisms.
4. Evolution: The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the Earth.
- Example: Charles Darwin's theory of evolution by natural selection revolutionized our understanding of how species change over time.
5. Gene: A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
- Example: Mutations in certain genes can lead to genetic disorders or diseases.
6. Gravity: The force that attracts a body toward the center of the Earth, or toward any other physical body having mass.
- Example: Gravity is what keeps the planets in orbit around the sun.
7. Atom: The basic unit of a chemical element, consisting of a nucleus containing protons and neutrons, surrounded by electrons in orbit.
- Example: Atoms combine to form molecules, which are the building blocks of matter.
8. DNA: Deoxyribonucleic acid, a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes.
- Example: DNA carries the genetic instructions necessary for the growth, development, functioning, and reproduction of organisms.
9. Climate Change: Long-term alteration in Earth’s climate and weather patterns, typically caused by human activities such as burning fossil fuels and deforestation.
- Example: The scientific consensus is clear that climate change poses significant risks to the environment and human societies.
10. Ecosystem: A biological community of interacting organisms and their physical environment.
- Example: Coral reefs are among the most diverse ecosystems on the planet, supporting a wide array of marine life.
