  • Question 1
    1 / -0
    Encephalitis is caused by the bite of
    Solution
    Encephalitis is an acute inflammation of the brain. Encephalitis can develop as a result of a direct infection to the brain by a virus, bacterium, or fungus, or when the immune system responds to a previous infection; the immune system mistakenly attacks brain tissue. Primary (infectious) encephalitis can be split into three main categories of viruses:
    1. Common viruses, including HSV (herpes simplex virus) and EBV (Epstein-Barr virus)
    2. Childhood viruses, including measles and mumps
    3. Arboviruses (spread by mosquitoes, ticks, and other insects), including Japanese encephalitis, West Nile encephalitis, and tick-borne encephalitis. Japanese encephalitis virus (JEV) is the causative agent of Japanese encephalitis, the leading cause of viral encephalitis in Asia. JEV transmission cycle involves mosquitoes and vertebrate hosts. In a study, it was detected that populations of Ae. albopictus and Cx. pipiens were efficient vectors for JEV transmission.

    So, the correct answer is 'Culex and Aedes.'.
  • Question 2
    1 / -0
    Match the correct relation as Anopheles to malaria
    Solution
    • The correct relation as Anopheles to malaria is Culex to elephantiasis because Anopheles mosquito serves as a vector for malaria and Culex mosquito serves as a vector for elephantiasis.
    • Culex and Anopheles are yellow-ish, but you can identify them by observing their resting position. Anopheles mosquitoes have a 45-degree angle, while Culex stays parallel to the surface.
    • Hence the correct relation as Anopheles to malaria is Culex-elephantiasis.
    • So, the correct answer is 'Culex-elephantiasis'.
  • Question 3
    1 / -0
    Which of the following phenomena improves due to physical exercise?
    Solution

  • Question 4
    1 / -0

    Solution

  • Question 5
    1 / -0
    Which of the following is a mishap associated with physical exercise?
    Solution
    Tearing of ligament is associated will physical exercise.
    Due to physical exercise, ligament can be strained beyond its normal range. The most common ligament injuries are ankle and knee tearing of ligament.
    option 'A' is correct.
  • Question 6
    1 / -0
    Disease caused by female Culex is
    Solution
    • Filaria spreads from person to person by female Culex mosquito bites. Symptoms include Highly swollen legs.
    • Thus, Option A is correct.
  • Question 7
    1 / -0
    Which one is correct match
    Solution
    • Culex is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals.
    • The diseases culex mosquito serves as vector include arbovirus infections such as West Nile virus, Encephalitis(inflammation of brain) Japanese encephalitis, or St. Louis encephalitis,filariasis.
    • Hence Encephalitis(disease)--Culex(vector) is a correct match.
    • So, the correct answer is 'Encephalitis--Culex'.
  • Question 8
    1 / -0
    Safe and effective means of producing artificial immunity against small pox by vaccine was first discovered by
    Solution
    • A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins.
    • The smallpox vaccine was discovered by Edward Jenner. It was the first successful vaccine ever to be developed and remains the only effective preventive treatment for the fatal smallpox disease.
    • Hence, safe and effective means of producing artificial immunity against smallpox by the vaccine was first discovered by Edward Jenner.
    So, the correct answer is 'Edward Jenner'.
  • Question 9
    1 / -0
