  • What are the seven properties of life?

    Order, Regulation, Growth and Development, Energy Processing, Response to Environment, Reproduction, and Evolutionary Adaptation.

  • Define biological order.

    Biological order refers to the highly organized structure of living organisms, from molecules to cells to organisms.

  • What is biological regulation?

    Regulation is the ability of organisms to maintain internal stability despite external changes (homeostasis).

  • Explain growth and development in living organisms.

    Growth and development involve the increase in size and the progression through life stages controlled by genetic information.

  • What does energy processing mean in biology?

    Energy processing is the use of energy by organisms to perform life activities like metabolism.

  • How do organisms respond to their environment?

    Response to environment is the ability to detect and react to stimuli for survival.

  • What is reproduction in biological terms?

    Reproduction is the process by which organisms produce offspring to continue their species.

  • Define evolutionary adaptation.

    Evolutionary adaptation is the process by which populations change over generations to better survive in their environment.

  • List the levels of biological organization from smallest to largest.

    Molecule, Organelle, Cell, Tissue, Organ, Organ System, Organism, Population, Community, Ecosystem, Biosphere.

  • What is a molecule in biological context?

    A molecule is a chemical structure consisting of atoms bonded together, essential for life.

  • Define organelle.

    An organelle is a specialized structure within a cell that performs a specific function.

  • What is the basic unit of life?

    The cell is the basic structural and functional unit of all living organisms.

  • Explain the role of tissues.

    Tissues are groups of similar cells that work together to perform a specific function.

  • What is an organ in biology?

    An organ is a structure composed of different tissues working together to perform a particular task.

  • Define organ system.

    An organ system is a group of organs that collaborate to carry out major body functions.

  • What constitutes an organism?

    An organism is an individual living entity capable of independent life.

  • What is a population in biology?

    A population is a group of organisms of the same species living in a specific area.

  • Define community in ecological terms.

    A community consists of all populations of different species living and interacting in an area.

  • What is an ecosystem?

    An ecosystem includes all living organisms in an area plus the physical environment with which they interact.

  • Describe the biosphere.

    The biosphere is the global sum of all ecosystems, encompassing all life on Earth and their environments.
