    Which of the following is a necessary characteristic of life (what do all living things have)?

    • All living things are made up of cells

    • All living things can move around

    • All living things have flagella

    • All living things have surface markers

    Correct Answer
    A. All living things are made up of cells
    Explanation
    All living things are made up of cells. This is a necessary characteristic of life because cells are the basic structural and functional units of all living organisms. Cells carry out essential processes such as metabolism, growth, reproduction, and response to stimuli. They also contain genetic material that allows for inheritance and the ability to evolve. Without cells, life as we know it would not exist.

    Which of the following characteristics of life do viruses have? (check all that apply)

    • They have genetic material (DNA or RNA)

    • They are made up of cells

    • They reproduce by themselves

    • They can carry out metabolic activities by themselves

    Correct Answer
    A. They have genetic material (DNA or RNA)
    Explanation
    Viruses have genetic material in the form of either DNA or RNA. This genetic material allows them to replicate and produce new viruses within a host cell. However, viruses are not considered to be living organisms because they lack the other characteristics listed. They are not made up of cells, they cannot reproduce by themselves, and they cannot carry out metabolic activities independently. Instead, they rely on host cells to provide the necessary machinery for their replication and survival.

    True or False: Viruses are living organisms

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Remember, viruses are NOT alive! They are just DNA/RNA wrapped in protein.

    Scientists have developed a medicine that destroys the cell walls of cells. They have found that this medicine works really well on bacteria. Would it work well on viruses?

    • Yes because viruses and bacteria have the same structure

    • Yes because viruses and bacteria both make people sick

    • No because viruses only have plasma membranes

    • No because viruses are not made up of cells and do not have a cell wall

    Correct Answer
    A. No because viruses are not made up of cells and do not have a cell wall
    Explanation
    Viruses are not made up of cells and do not have a cell wall. The medicine that destroys the cell walls of cells would not be effective on viruses because they do not possess this structure. Viruses have a different structure compared to bacteria, and therefore, the medicine that works on bacteria would not work well on viruses.

    Which cell could this virus infect (look at the shape of its surface markers compared to the cell) - ProProfs

    Which cell could this virus infect (look at the shape of its surface markers compared to the cell)

    • Option 1

    • Option 2

    • Option 3

    Correct Answer
    A. Option 2
    Explanation
    The virus could infect Option 2 because the shape of its surface markers matches that of the virus.

    What viral structure is labeled with box a? - ProProfs

    What viral structure is labeled with box a?

    • Protein Coat

    • DNA/RNA

    • Plasma Membrane

    • Surface Markers

    Correct Answer
    A. Protein Coat
    Explanation
    The correct answer is Protein Coat. The viral structure labeled with box a is the protein coat, also known as the capsid. The protein coat protects the genetic material (DNA or RNA) of the virus and helps in the attachment and entry of the virus into host cells. It plays a crucial role in the viral replication and infection process.

    What is the purpose of the structure labelled c? - ProProfs

    What is the purpose of the structure labelled c?

    • To allow food into cell and wastes out of cell

    • To protect the virus from harmful cells

    • To hold the cell's genetic information

    • To attach to host cells

    Correct Answer
    A. To attach to host cells
    Explanation
    The purpose of the structure labelled c is to attach to host cells. This means that the structure is responsible for binding to the surface of the host cell, allowing the virus to enter and infect the host cell. By attaching to host cells, the virus can then enter the cell and carry out its reproductive cycle.

    You're looking at a sample from your patient under the microscope. Does your patient have a virus? - ProProfs

    You're looking at a sample from your patient under the microscope. Does your patient have a virus?

    • Yes, my patient has a virus

    • No, this is a prokaryotic cell

    • No, this is a eukaryotic cell

    • No, viruses are always made up of cells

    Correct Answer
    A. No, this is a prokaryotic cell
    Explanation
    The correct answer is "No, this is a prokaryotic cell." This is because prokaryotic cells are a type of cell that do not have a nucleus or other membrane-bound organelles. Viruses, on the other hand, are not considered cells as they are acellular particles that require a host cell to replicate. Therefore, if the sample under the microscope is identified as a prokaryotic cell, it means that it is not a virus.
