  • What is biology?

    Biology is the scientific study of life.

  • How do biologists recognize life?

    Life is recognized mainly by what living things do, such as growth, reproduction, and energy processing.

  • What are the major properties associated with life?

    Order, cells, growth and development, energy processing, regulation, response to the environment, reproduction, and evolution.

  • Why is a virus generally not considered a living organism?

    Viruses have an ordered structure but cannot process energy or are composed of cells, so they lack all properties of life.

  • What does the property 'order' refer to in living organisms?

    Order refers to the organized structure, such as the arrangement of cells or body parts.

  • What is the significance of cells in living organisms?

    Cells are the basic structural and functional units of life in all living organisms.

  • What does growth and development mean in biology?

    Growth and development refer to the process by which an organism matures and changes over time.

  • What is energy processing in living organisms?

    Energy processing is the ability to take in energy and use it for metabolic activities.

  • What is regulation in the context of life?

    Regulation is the ability of an organism to maintain internal stability, such as temperature or salt balance.

  • How do living organisms respond to their environment?

    Living organisms detect and respond to environmental stimuli to survive and adapt.

  • What is reproduction in biological terms?

    Reproduction is the process by which organisms produce new individuals, ensuring species continuation.

  • What role does evolution play in life?

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

  • How does the sea turtle regulate salt levels?

    Sea turtles regulate salt by excreting excess salt through their eyes.

  • What is an example of growth and development in sea turtles?

    Sea turtles grow from hatchlings into mature adults over several decades.

  • How do sea turtle hatchlings respond to environmental temperature?

    Warmer temperatures favor female development, while cooler temperatures favor male development.

  • What is the significance of the Mars rover Curiosity in biology?

    Curiosity searches for chemical evidence of past or present life on Mars by detecting energy-processing substances.

  • Why is Enceladus considered a likely place to find extraterrestrial life?

    Enceladus has abundant water and geothermal activity, which may support life.

  • Can nonliving objects display some properties of life?

    Yes, but they do not display all properties simultaneously, which is required to be considered alive.

  • What distinguishes living things from nonliving things?

    Living things display all key properties of life simultaneously, unlike nonliving things.

  • What is the importance of cells in large organisms like sea turtles?

    Large organisms are made of trillions of cells that perform specialized functions.
