Choose the correct answers from the alternatives given.
Which of the following is the most accurate general description of the kingdom Protista?

  1. Eukaryotic, photosynthetic or heterotrophic organisms that inhabit moist environments, form resistant cysts, and reproduce with flagellated gametes

  2. Relatively simple versions of plants, animals and fungi

  3. Eukaryotic, unicellular organisms that may be photosynthetic or heterotrophic

  4. Eukaryotic, heterotrophic and/or photosynthetic, unicellular or simple multicellular organisms, which are different enough from multicellular plants, fungi, or animals to be placed in this diverse group
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Kingdom Protista is a group in of eukaryotic organisms which have a true nucleus, they are usually unicellular and the cells of these organisms contain nucleus which is bound to the organelle,  algae are one of the classifications of protista which are photosynthetic organisms that are mostly found in freshwater sources or marine lakes. Protists are heterotrophic organism & on the other hand, has to acquire nutrition from other organisms such as plants or animals to survive.

So, the correct option is 'Eukaryotic, unicellular organisms that may be photosynthetic or heterotrophic'.

Name the bacteria that cause anthrax disease in animals.

  1. Proteus morganii

  2. Borrelia bacteria

  3. Bacillus anthracis

  4. Trichinella spiralis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Anthrax is an infection that is caused by the bacteria Bacillus anthracis. These bacteria form spores that are hard-shelled, dormant versions of the bacteria. Spores are the form of the bacteria that cause infection. They can survive in the soil for many decades. Anthrax most commonly occurs in animals such as pigs, cattle, horses, and goats, but it can also infect people.
So the correct option is  'Bacillus anthrcis'

E Correct answer
Explanation

Example of Bioweapon_


(1) Anthrax:-  It is caused by a spore-forming bacterium. It mainly affects animals. Humans can become infected through contact with an infected animal or by inhaling spores.

(2) Cholera:- A bacteria disease causing severe diarrhea and dehydration usually spread in water.

(3) Plague:-  The bubonic plague is caused by the disease yersinia pestis. It can spread through contact with infected fleas.

(4) Ebola:-   A virus that causes severe bleeding, organ failure and can lead to death. The human may spread the virus to other humans through contact with bodily fluids such as blood.

Which famous biologist attenuated. the germs of anthrax disease by heating them and inoculated sheep with them, thus making the sheep resistant to anthrax? 

  1. Lazaro Spailanzani

  2. Louis Pasteur

  3. Joseph Lister

  4. Francesco Redi
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pasteur discovered that growing anthrax bacilli at about 42 °C made them unable to produce spores.  . His laboratory notebooks, now  show that he actually used heat and potassium dichromate similar to Toussaint's method, followed by inoculation of the tested animals with the weakened innoculum. The experiment, conducted  by him at Pouilly-le-Fort on sheep, goats and cows, was successful.

So, the correct answer is B. (Louis pasteur )
