  • What is biology?

    Biology is the scientific study of life and living organisms, including their structure, function, growth, evolution, and distribution.

  • What are the main characteristics of living organisms?

    Living organisms exhibit organization, metabolism, homeostasis, growth, reproduction, response to stimuli, and adaptation.

  • Define homeostasis.

    Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes.

  • What is the cell theory?

    The cell theory states that all living things are made of cells, cells are the basic unit of life, and all cells come from pre-existing cells.

  • What are the two main types of cells?

    The two main types of cells are prokaryotic (without a nucleus) and eukaryotic (with a nucleus).

  • What is metabolism?

    Metabolism refers to all chemical reactions that occur within an organism to maintain life.

  • Explain the concept of evolution in biology.

    Evolution is the process by which populations of organisms change over generations through genetic variation and natural selection.

  • What is the role of DNA in living organisms?

    DNA contains the genetic instructions used in growth, development, functioning, and reproduction of all living organisms.

  • Define reproduction in biological terms.

    Reproduction is the biological process by which new individual organisms are produced, ensuring species survival.

  • What is the importance of adaptation?

    Adaptation allows organisms to adjust to their environment, increasing their chances of survival and reproduction.

  • Describe the hierarchical organization of life.

    Life is organized from molecules to cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and the biosphere.

  • What is the scientific method in biology?

    The scientific method is a systematic process of observation, hypothesis formation, experimentation, and conclusion to understand natural phenomena.

  • Why is biodiversity important?

    Biodiversity ensures ecosystem resilience, provides resources, and supports ecological balance.

  • What is the difference between autotrophs and heterotrophs?

    Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy.

  • Define ecology.

    Ecology is the study of interactions between organisms and their environment.

  • What is a hypothesis?

    A hypothesis is a testable prediction or explanation for a scientific question.

  • Explain the importance of cells in biology.

    Cells are the fundamental units of life, performing all necessary functions to sustain an organism.

  • What is natural selection?

    Natural selection is the process where organisms better adapted to their environment tend to survive and reproduce.

  • What role do enzymes play in biological systems?

    Enzymes act as catalysts to speed up chemical reactions in living organisms without being consumed.

  • What is the difference between growth and development?

    Growth is an increase in size or number of cells, while development is the progression of changes in form and function.
