    What is the main purpose of a flagella on a bacterial cell?

    • Obtaining and digesting food

    • Locomotion (movement)

    • Attaching to another cell for entry

    • It has no purpose, it is a vestigal structure

    • It looks cool!

    Correct Answer
    A. Locomotion (movement)
    Explanation
    The main purpose of a flagella on a bacterial cell is locomotion or movement. Flagella are long, whip-like structures that extend from the cell surface and enable bacteria to move towards favorable environments or away from harmful substances. This movement is essential for bacterial survival and allows them to explore their surroundings, find nutrients, and escape from potential threats.

    It is most effective to wash your hands

    • In warm water

    • In warm water with soap

    • In cold water

    • Any of the above are effective

    • Non of the above are effective

    Correct Answer
    A. In warm water with soap
    Explanation
    Washing hands in warm water with soap is the most effective method because warm water helps to remove dirt and oil from the skin more effectively than cold water. Soap helps to break down and remove germs and bacteria from the hands, further enhancing the effectiveness of handwashing. Cold water alone may not be as effective in removing dirt and germs, while washing hands without soap may not adequately eliminate bacteria and viruses. Therefore, washing hands in warm water with soap is the best option for thorough hand hygiene.

    Gram Positive bacteria will stain:

    • Amber

    • Brown

    • Pink

    • Purple

    • Teal

    Correct Answer
    A. Purple
    Explanation
    Gram positive bacteria will stain purple. This is because they have a thick peptidoglycan layer in their cell wall, which retains the crystal violet stain during the Gram staining process. The stain is then fixed with iodine and decolorized with alcohol, causing the purple color to remain in gram positive bacteria. In contrast, gram negative bacteria have a thinner peptidoglycan layer and an outer membrane, which allows the stain to be washed away during the decolorization step, resulting in a pink color when counterstained with safranin.

    This form of bacterial reprodcution produces genetic clones of the original bacteria cell

    • Conjugation

    • Endospore production

    • Binary fission

    • Binary fusion

    • None of the above

    Correct Answer
    A. Binary fission
    Explanation
    Binary fission is a form of bacterial reproduction where a single cell divides into two identical daughter cells. This process produces genetic clones of the original bacteria cell because the genetic material is replicated and evenly distributed between the two daughter cells. Conjugation involves the transfer of genetic material between two bacterial cells, while endospore production is a method of bacterial survival under unfavorable conditions. Binary fusion is not a recognized form of bacterial reproduction. Therefore, the correct answer is binary fission.

    • Staphylococci

    • Streptococci

    • Diplococci

    • Staphylobaccillus

    • Streptobaccillus

    Correct Answer
    A. Streptococci
    Explanation
    Streptococci is the correct answer because it is a type of bacteria that is round and forms chains. Staphylococci, on the other hand, are round bacteria that form clusters. Diplococci are round bacteria that form pairs. Staphylobaccillus and Streptobaccillus are not valid names for bacteria.

    Bacteria found in extreme environments are found in this kingdom

    • Eubacteria

    • Ubacteria

    • Archebacteria

    • Fungi

    • Protista

    Correct Answer
    A. Archebacteria
    Explanation
    Archebacteria, also known as Archaea, are a group of microorganisms that are found in extreme environments such as hot springs, deep-sea hydrothermal vents, and salt lakes. These bacteria have unique characteristics that allow them to survive in these harsh conditions, such as the ability to tolerate high temperatures, high salinity, and acidic or alkaline pH levels. Therefore, the correct answer is Archebacteria.

    In sexual reprodcution (conjugation) bacteria exchange information throug the _________ of the bacteria

    • Flagella

    • Cell wall

    • Pilli

    • Capsule

    • Chromosome

    Correct Answer
    A. Pilli
    Explanation
    In sexual reproduction (conjugation), bacteria exchange genetic information through the pili. Pili are hair-like structures that extend from the surface of bacteria and are involved in the transfer of DNA between cells. They allow the bacteria to adhere to surfaces and facilitate the exchange of genetic material, which can lead to genetic variation and evolution.

    A bacteria named Staphylobaccilus would be: (hint, what does staph mean and what does baccilus mean?

    • Rod shapped and clustered

    • Rod shapped and in chains

    • Sphere shapped and clustered

    • Sphere shapped and in chains

    • Spiral shapped and clustered

    Correct Answer
    A. Rod shapped and clustered
    Explanation
    The word "staph" in Staphylobaccilus refers to the genus Staphylococcus, which are bacteria that are typically rod-shaped. The term "bacillus" means rod-shaped as well. Therefore, a bacteria named Staphylobaccilus would be rod-shaped. Additionally, the term "clustered" suggests that the bacteria are found in clusters rather than in chains, spheres, or spirals.

    We heat up and refridgerate food because it helps to:

    • It helps us avoid bacterial growth that could make us ill

    • It helps us avoid viral growth that could make us ill

    • It allows us to prevent endospores from forming and being transported into the air for other transport

    • All of the above

    • None of the above

    Correct Answer
    A. It helps us avoid bacterial growth that could make us ill
    Explanation
    Heating up and refrigerating food helps us avoid bacterial growth that could make us ill. Bacteria multiply rapidly in warm environments, so heating up food kills or inhibits the growth of bacteria. Refrigeration slows down the growth of bacteria, as they thrive at temperatures between 40°F (4°C) and 140°F (60°C). By preventing bacterial growth, we reduce the risk of foodborne illnesses caused by consuming contaminated food.

    When you collected bacteria from around the school, their main source of food was:

    • Particles in the air contained within the petri dish

    • Other microbes that were brought into the dish with the bacteria sample

    • Organic material that followed them from where they were collected

    • The agar in the petri dish

    • All of the above

    Correct Answer
    A. The agar in the petri dish
    Explanation
    The agar in the petri dish is the main source of food for the collected bacteria. Agar is a gelatinous substance derived from seaweed and it provides essential nutrients for bacterial growth. The other options, such as particles in the air, other microbes, and organic material, may also contribute to the bacteria's food source, but the agar is the primary and most significant source of nutrition in the petri dish.
