  • 2. 

    __________infect your cells and make them lyse (break open)

    • A.

      Bacteria

    • B.

      Viruses

    Correct Answer
    B. Viruses
    Explanation
    Viruses can infect your cells and cause them to lyse or break open. Unlike bacteria, viruses are not considered living organisms as they cannot reproduce or carry out metabolic processes on their own. Instead, viruses rely on host cells to replicate. Once inside a host cell, viruses hijack the cell's machinery to produce more viral particles, eventually causing the cell to burst and release the newly formed viruses. This process of cell lysis is a common mechanism used by viruses to spread and infect other cells in the body.

    __________have surface markers which help them attach to and infect specific cells

    • A.

      Bacteria

    • B.

      Viruses

    Correct Answer
    B. Viruses
    Explanation
    Viruses have surface markers that enable them to attach to and infect specific cells. These surface markers, also known as viral attachment proteins, allow the virus to recognize and bind to specific receptors on the surface of host cells. This interaction is crucial for the virus to gain entry into the host cell and initiate the infection process. In contrast, bacteria do not have surface markers that specifically target and attach to host cells in the same way as viruses.

  • 4. 

    __________release toxins (poisons) which hurt our cells

    • A.

      Bacteria

    • B.

      Viruses

    Correct Answer
    A. Bacteria
    Explanation
    Bacteria release toxins (poisons) which hurt our cells. This is because bacteria are single-celled microorganisms that can produce and release toxic substances as part of their natural defense mechanisms or as a byproduct of their metabolic processes. These toxins can damage and destroy our body's cells, leading to various harmful effects and symptoms of bacterial infections. On the other hand, viruses are not capable of releasing toxins themselves, as they are much smaller and simpler than bacteria and rely on host cells to reproduce and cause harm.

  • 5. 

    __________are made of cells and can reproduce on their own

    • A.

      Bacteria

    • B.

      Viruses

    Correct Answer
    A. Bacteria
    Explanation
    Bacteria are made of cells and can reproduce on their own. Bacteria are single-celled organisms that have a complete cellular structure, including a cell membrane, cytoplasm, and genetic material. They are capable of carrying out all necessary life processes independently. In contrast, viruses are not considered living organisms as they lack cellular structure and cannot reproduce on their own. They require a host cell to replicate and carry out their life cycle.

    Rate this question:

  • 6. 

    __________need a host cell in order to reproduce and perform metabolic activities (use energy)

    • A.

      Bacteria

    • B.

      Viruses

    Correct Answer
    B. Viruses
    Explanation
    Viruses need a host cell in order to reproduce and perform metabolic activities because they lack the necessary cellular machinery to carry out these processes on their own. Unlike bacteria, which are single-celled organisms capable of independent growth and reproduction, viruses are acellular particles that rely on the host cell's machinery to replicate their genetic material and produce new viral particles. Additionally, viruses lack the ability to generate energy on their own and depend on the host cell's metabolic processes to obtain the necessary energy for their survival and replication.
