Colourless, unicellular, cell wall bound, spherical or rod-shaped micro-organism lacking organized nucleus is called as

  1. Mycoplasma

  2. Virus

  3. Bacteria

  4. Cyanobacteria
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

According to five kingdom classification, bacteria are placed in kingdom monera. Organisms of kingdom monera are single celled and they have cell wall made up of peptidoglycans. Their nuclear membrane is absent, have single chromosome and do not have membrane bound cell organelles. DNA is double stranded and suspended in cytoplasm (called nucleoid).

  2. Plague- Yersinia pestis

  3. Syphilis- Trichuris trichiura

  4. Sleeping sickness- Trypanosoma Gambiense
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dengue is the most common arboviral disease.
Plague is caused by the bacterium, Yersinia pestis.
Sleeping sickness is a parasitic disease of humans and other animals and is caused by the protozoa, Trypanosoma gambiense or T. brucei.
Syphilis is a sexually transmitted disease caused by the spirochete bacterium, Treponema pallidum. While Trichuris trichiura causes trichuriasis, a type of helminthic infection.
Therefore, the correct answer is option C.

Encephalitis is a viral disease of humans which is transmitted by

  1. Anopheles

  2. Culex

  3. Aedes

  4. Culex and Aedes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Encephalitis is acute inflammation (swelling up) of the brain resulting either from a viral infection or when the body's own immune system mistakenly attacks brain tissue. The most common cause is a viral infection. Encephalitis occurs in 1 in every 1,000 cases of measles. Encephalitis generally begins with fever and headache. The symptoms rapidly worsen and there may be seizures (fits), confusion, drowsiness and loss of consciousness and even coma. It is transmitted to humans through the bite of infected Culex species mosquitoes, particularly Culex tritaeniorhynchus.
