Questions and Answers
  • 1. 

    The ________ attaches to the Antigen.

    Explanation
    An antibody is a protein produced by the immune system in response to the presence of an antigen. Antibodies specifically recognize and bind to antigens, which are foreign substances or molecules that can trigger an immune response. This binding of antibodies to antigens is crucial for the immune system to identify and neutralize pathogens or other harmful substances in the body. Therefore, the correct answer is "antibody" because it is the molecule that attaches to the antigen.

    Pathogenesis of Influenza

    • A.

      It is looking for brain cells

    • B.

      Social pressures

    • C.

      It is trying to replicate

    • D.

      It is looking for the liver

    Correct Answer
    C. It is trying to replicate
    Explanation
    The correct answer is "It is trying to replicate." Influenza is a viral infection that primarily affects the respiratory system. Once the virus enters the body, it attaches itself to the cells lining the respiratory tract and starts to replicate. This replication process allows the virus to multiply and spread throughout the body, causing symptoms such as fever, cough, and body aches. Therefore, the main objective of the influenza virus is to replicate itself within the host's cells.

    Rate this question:

  • 6. 

    How is Influenza transmitted?

    • A.

      Airborne respiratory secretions

    • B.

      Airborne vehicles

    • C.

      Skin to skin contact

    • D.

      Looking at someone too long who already has it

    Correct Answer
    A. Airborne respiratory secretions
    Explanation
    Influenza is transmitted through airborne respiratory secretions. When an infected person coughs or sneezes, tiny droplets containing the influenza virus are released into the air. These droplets can be inhaled by others nearby, leading to the spread of the virus. This is why it is important to cover your mouth and nose when coughing or sneezing, and to maintain good respiratory hygiene to prevent the transmission of influenza.

    Rate this question:

  • 7. 

    What is the Incubation period for influenza?

    • A.

      2-3 days

    • B.

      1-2 days

    • C.

      4-5 days

    • D.

      1-2 weeks

    Correct Answer
    B. 1-2 days
    Explanation
    The incubation period for influenza is the time between when a person is exposed to the virus and when symptoms start to appear. In the case of influenza, the incubation period is typically 1-2 days. This means that after being exposed to the virus, it usually takes 1-2 days for someone to start experiencing symptoms such as fever, cough, and body aches. It is important to note that the incubation period can vary from person to person, and some individuals may show symptoms sooner or later than the average timeframe.

    What is the pathogen and host for malaria?

    • A.

      Yersinia Pestis, small animals (fleas, dogs, cats, ...)

    • B.

      Plasmodium falciporate, female anopheles

    Correct Answer
    B. Plasmodium falciporate, female anopheles
    Explanation
    The correct answer is Plasmodium falciporate, female anopheles. Malaria is caused by the parasite Plasmodium falciporate, which is transmitted to humans through the bite of infected female Anopheles mosquitoes. The mosquitoes act as the host for the parasite, allowing it to complete its life cycle and reproduce. Once inside a human host, the parasite infects red blood cells and can cause symptoms such as fever, chills, and fatigue.

    Rate this question:

  • 9. 

    Do you need to know the life cycle of malaria for the test?

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    Knowing the life cycle of malaria is important for the test because it helps in understanding the transmission, progression, and control of the disease. It provides information about the different stages of the parasite's life cycle, including its development in mosquitoes and humans. This knowledge is crucial for diagnosing and treating malaria effectively, as well as implementing preventive measures to reduce its spread. Therefore, having an understanding of the life cycle of malaria is necessary for a comprehensive understanding of the disease and its management.

    Rate this question:

  • 10. 

    What are some ways that Malaria evades the human immune system?

    • A.

      Merosome is cloaked in liver cell lining, or trophozoite in the red blood cell

    • B.

      Invisibility cloak

    • C.

      Bending the light around it

    • D.

      Canceling the light particles around it

    Correct Answer
    A. Merosome is cloaked in liver cell lining, or trophozoite in the red blood cell
    Explanation
    Malaria is able to evade the human immune system by cloaking itself in the lining of liver cells or by hiding within red blood cells. This allows the parasite to go undetected by the immune system and continue to replicate and cause infection. This strategy acts as an "invisibility cloak" for the parasite, making it difficult for the immune system to recognize and eliminate the infection. By utilizing this mechanism, malaria is able to persist and cause ongoing harm to the host.

  • 12. 

    Malaria caused the US government to use what chemical to eradicate it?

    • A.

      Clorox

    • B.

      Bleach

    • C.

      DDT

    • D.

      Deet

    Correct Answer
    C. DDT
    Explanation
    DDT is the correct answer because it was a chemical widely used by the US government in the mid-20th century to eradicate malaria. DDT, or dichlorodiphenyltrichloroethane, was an effective insecticide that helped control the mosquito population responsible for spreading malaria. Its use significantly reduced malaria cases in the United States and other countries. However, due to its harmful effects on the environment and human health, DDT was eventually banned in many countries.

    What type of plague was the black plague?

    • A.

      Bubonic

    • B.

      Septacaemic

    • C.

      Pneumonic

    Correct Answer
    A. Bubonic
    Explanation
    The black plague, also known as the Black Death, was caused by the bacterium Yersinia pestis. It primarily spread through fleas that infested rats, which were then transmitted to humans through flea bites. The bubonic plague was the most common form of the disease during the black plague pandemic. It was characterized by swollen and painful lymph nodes, known as buboes, which were often found in the groin, armpit, or neck. This form of plague caused high fever, chills, fatigue, and eventually death if left untreated.

    • C.

      It wants your first born child

    Correct Answer
    B. It is trying to replicate
    Explanation
    The correct answer is "It is trying to replicate." The pathogenesis of the Black Plague refers to the process by which the disease reproduces and spreads within the body. The Black Plague, caused by the bacterium Yersinia pestis, replicates within the lymphatic system of infected individuals, leading to the characteristic symptoms and transmission to others. Understanding the pathogenesis of the disease is crucial in developing effective treatments and preventive measures.

    Rate this question:

  • 19. 

    What was the mortality rate of the plague if left untreated?

    • A.

      40-50%

    • B.

      20-60%

    • C.

      30-60%

    Correct Answer
    C. 30-60%
    Explanation
    The mortality rate of the plague if left untreated was estimated to be between 30-60%. This means that out of every 100 people infected with the plague and not receiving any treatment, around 30-60 of them would die. The wide range in the estimate is likely due to various factors such as the strain of the plague, the overall health of the population, and the availability of medical resources.

    Rate this question:

  • 20. 

    How soon do symptoms show from the plague?

    • A.

      1-2 hours

    • B.

      1-2 days

    • C.

      20-50 days

    • D.

      30-60 days

    Correct Answer
    D. 30-60 days
    Explanation
    The correct answer is 30-60 days. This is because the incubation period for the plague, which is the time between being infected and showing symptoms, can range from 2 to 6 days for the bubonic plague, and up to 10 days for the pneumonic plague. However, in rare cases, the incubation period can be as long as 30-60 days. During this time, the bacteria multiply and spread in the body before symptoms such as fever, chills, weakness, and swollen lymph nodes appear.

    Antegenic shift happens at a ____ pace, whereas antegenic drift happens at a ____ pace.

    • A.

      Fast, slow

    • B.

      Slow, fast

    Correct Answer
    A. Fast, slow
    Explanation
    Antigenic shift refers to a rapid change in the antigenic properties of a virus, typically occurring when two or more different strains of the virus combine to form a new strain. This process happens at a fast pace. On the other hand, antigenic drift refers to a slow and gradual change in the antigenic properties of a virus over time, usually due to mutations in the viral genome. Therefore, antigenic drift happens at a slow pace.
