    Which one is a characteristic that all living things have in common?

    • Use sunlight

    • Use energy

    Correct Answer
    A. Use energy
    Explanation
    All living things require energy to carry out their life processes, such as growth, reproduction, and movement. Energy is needed for essential functions like metabolism and maintaining homeostasis. Without energy, living organisms would not be able to survive or perform necessary tasks. Therefore, the characteristic of using energy is something that all living things have in common.

    Rate this question:

  • 3. 

    The _____ are the powerhouse of the cell. They provide energy.

    • Mitochondria

    • Ribosomes

    Correct Answer
    A. Mitochondria
    Explanation
    Mitochondria are known as the powerhouse of the cell because they are responsible for producing the majority of the cell's energy in the form of adenosine triphosphate (ATP) through cellular respiration. They have their own DNA and are capable of self-replication, which suggests that they were once free-living organisms that formed a symbiotic relationship with eukaryotic cells. This organelle contains enzymes and proteins that carry out the biochemical reactions necessary for energy production, making it vital for the cell's survival and functioning.

    Rate this question:

  • 4. 

    Which is a part of the cell theory?

    • All organisms need food.

    • All cells come from existing cells

    Correct Answer
    A. All cells come from existing cells
    Explanation
    The cell theory states that all living organisms are composed of cells, cells are the basic unit of structure and function in living organisms, and all cells arise from pre-existing cells. This means that new cells are formed through cell division, rather than spontaneously appearing. This principle is supported by scientific evidence and observations, such as the discovery of cell division and the absence of any evidence of cells forming from non-living matter.

    Rate this question:

  • 5. 

    How many domains are there today?

    • Three

    • Six

    Correct Answer
    A. Three
    Explanation
    Today, scientific classification recognizes three fundamental domains of life: Bacteria, Archaea, and Eukarya. These domains distinguish organisms based on genetic characteristics and cellular structures. Bacteria and Archaea consist of prokaryotic cells without a nucleus, with archaea often found in extreme environments, highlighting their unique adaptations. Eukarya, on the other hand, includes all eukaryotic organisms whose cells feature a nucleus enclosed by membranes, encompassing plants, animals, fungi, and protists. This three-domain system, proposed by Carl Woese in 1990, provides a comprehensive framework for understanding the profound genetic and cellular diversity among living organisms.

    Rate this question:

  • 6. 

    The ____ is the control center of the cell.

    • Cytoplasm

    • Nucleus

    Correct Answer
    A. Nucleus
    Explanation
    The nucleus is the control center of the cell because it contains the cell's genetic material, DNA. It regulates the cell's activities by controlling the synthesis of proteins and the replication of DNA. The nucleus also houses the nucleolus, which produces ribosomes involved in protein synthesis. Additionally, the nucleus controls the cell's growth, division, and differentiation.

    Rate this question:

  • 7. 

    Which is a  part of the cell theory?

    • The cell is the basic unit of all living things.

    • All living things need oxygen.

    Correct Answer
    A. The cell is the basic unit of all living things.
    Explanation
    The cell theory is a fundamental principle in biology that states that the cell is the basic unit of all living things. This means that all living organisms, regardless of their complexity, are composed of cells. This principle was proposed by scientists Schleiden and Schwann in the 19th century, and it revolutionized our understanding of life and paved the way for further discoveries in cell biology. The statement "The cell is the basic unit of all living things" aligns perfectly with the cell theory and is therefore a part of it.

    • Live in their environment

    • Respond to their environment

    Correct Answer
    A. Respond to their environment
    Explanation
    All living things have the characteristic of responding to their environment. This means that they are able to detect and react to stimuli in their surroundings. This response can be in the form of movement, growth, or changes in behavior. It is a fundamental trait of living organisms that allows them to adapt and survive in their environment.

    Rate this question:

  • 9. 

    How many kingdoms are there currently?

    • Six

    • Seven

    Correct Answer
    A. Six
    Explanation
    The current system of biological classification divides living organisms into six kingdoms, which are Archaea, Bacteria, Protista, Fungi, Plantae, and Animalia. These kingdoms categorize organisms based on critical factors such as cellular structure, mode of nutrition, and evolutionary relationships. The classification begins at a broader level with three domains—Bacteria, Archaea, and Eukarya—under which these six kingdoms fall. This structure allows scientists to specify characteristics and lineage more accurately, recognizing the vast diversity within and across these groups. The six-kingdom system is a refined model that enhances our understanding of biological complexities and the natural relationships among different organisms.
