    How does bacteria move?more then one answer

    • A.

      Move by rushing fluid

    • B.

      Move by flagellum

    • C.

      By attaching itself to cells

    Correct Answer(s)
    A. Move by rushing fluid
    B. Move by flagellum
    Explanation
    Bacteria can move in multiple ways. One way is by rushing fluid, where they use the flow of liquid to propel themselves forward. Another way is through the use of flagella, which are whip-like structures that rotate and allow bacteria to swim. These two mechanisms enable bacteria to move efficiently and explore their environment.

    How does bacteria get transmitted?

    • A.

      Hands

    • B.

      Insects

    • C.

      Cold weather

    • D.

      Microwaved food unproperly

    Correct Answer(s)
    A. Hands
    B. Insects
    D. Microwaved food unproperly
    Explanation
    Bacteria can be transmitted through various means, including hands, insects, and improperly microwaved food. Hands can easily pick up bacteria from contaminated surfaces and transfer them to other objects or people through touch. Insects, such as flies or cockroaches, can carry bacteria on their bodies or in their digestive systems, spreading them when they come into contact with food or surfaces. Improperly microwaved food can also harbor bacteria if it is not heated to a high enough temperature to kill them. Therefore, all three options mentioned in the answer can contribute to the transmission of bacteria.

    How does a virus reproduce?

    • A.

      With a female virus

    • B.

      By controlling a cell to make copies

    • C.

      They cant reproduce

    Correct Answer
    B. By controlling a cell to make copies
    Explanation
    Viruses reproduce by taking control of a host cell and using its machinery to produce more copies of themselves. They inject their genetic material into the host cell, which then follows the virus's instructions to create new viral components. These components are assembled into complete viruses, which are released from the host cell to infect other cells and continue the cycle of reproduction. This process allows viruses to spread and cause infections in living organisms.

    An autotroph is a bacteria which gets its energy from ________

    Correct Answer
    photosythesis
    sun
    Explanation
    Autotrophs are organisms that can produce their own food using energy from external sources. In this case, the autotroph being referred to is a bacteria. Bacteria that are autotrophs can obtain their energy through photosynthesis, a process in which they convert sunlight into chemical energy. Therefore, the correct answer is photosynthesis and sun, as autotrophic bacteria can harness the energy from the sun through photosynthesis to produce their own food.

    An heterotroph is a bacteria which gets its energy from

    Correct Answer
    autotrophs
    eating
    Explanation
    Heterotrophs are organisms that cannot produce their own food and rely on consuming other organisms for energy. In this case, the bacteria mentioned is a heterotroph that obtains its energy by consuming autotrophs. Autotrophs, on the other hand, are organisms capable of producing their own food through processes like photosynthesis. Therefore, the bacteria in question obtains its energy by feeding on autotrophs.

    How does a virus get energy?

    • A.

      It produces energy

    • B.

      From host cell

    • C.

      They dont need it

    Correct Answer
    B. From host cell
    Explanation
    A virus gets energy from the host cell because it lacks the necessary cellular machinery to produce energy on its own. Once inside a host cell, the virus hijacks the cell's metabolic processes and utilizes its resources to replicate and produce new viral particles. This energy acquisition from the host cell is crucial for the virus's survival and propagation within the host organism.

    How does bacteria get energy

    • A.

      They dont need it

    • B.

      Binary fission

    • C.

      Conjuction

    • D.

      Mitosis

    Correct Answer(s)
    B. Binary fission
    C. Conjuction
    Explanation
    Bacteria obtain energy through a process called binary fission, which is a form of asexual reproduction. During binary fission, a single bacterium divides into two identical daughter cells. This process allows bacteria to multiply and increase their population. Conjugation, on the other hand, is a method of genetic exchange between bacteria, but it does not directly provide them with energy. Mitosis is a process that occurs in eukaryotic cells, not bacteria, where a single cell divides into two identical daughter cells.
