Question 1
1 / -0

Inoculation of a suspension of killed or attenuated pathogenic micro-organisms to stimulate the formation of antibodies is known as

A
Vaccination

B
Antibiotic treatment

C
Serum therapy

D
Transplantation
Solution
- A vaccine contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbes, its toxins or one of its surface proteins.
- The agent stimulates the body's immune system to recognize the agent as a threat, destroy it and keep a record of it so that the immune system can more easily recognize and destroy any of these microbes that it later encounters.
So the correct answer is the option 'Vaccination'.

Cholera is an infectious disease, that causes severe watery diarrhea, leading to dehydration. If untreated, it may lead to the death of the person. Cholera is caused by consuming contaminated food or water. The bacteria responsible for causing the disease is a bacterium, called Vibrio cholerae. The disease is most common in places with poor sanitation, crowding, war, and famine.

C
$70^{0}$ 'C for 60 minutes

D
$80^{0}$ C for 30 minutes

Solution

In the classic pasteurization treatment of milk, the milk was exposed to a temperature of about $63^{0}$ C for 30 minutes. Most milk pasteurization today uses higher temperatures, at least $72^{0}$ C, but for only 15 seconds.

B
15th August

C
25th April

D

Question 6
1 / -0

Vaccines are prepared from:

A
Vitamins

B
Blood

C
Attenuated bacteria or inactivated viruses

D
Plasma

Solution

A vaccine contains weakened or inactivated microorganisms such as bacteria or viruses. These inactive organisms trigger an immune response by producing antibodies within the body. These antibodies protect the body from further infection. Thus, the correct answer is option (C),
Question 7
1 / -0

Heating milk at $70^{0}$ followed by sudden cooling is known as ______________.

A
Sterilization

B
Preservation

C
Pasteurization

D
Fermentation

Solution

The milk is heated to about 70 degree celsius for 15 to 30 seconds and then suddenly chilled and stored. By doing so, it prevents the growth of microbes. This process was discovered by Louis Pasteur. It is called pasteurization.
Question 8

A
Tuberculosis

B
Cholera

C
Jaundice

D
Brain fever

Solution

It is transmitted by the small particles or droplet nuclei that harbor these pathogens. When a person suffering from this disease sneezes, coughs or talks the pathogen in the droplet nuclei are carried by air. This may infect another person who inhales these droplet nuclei. Thus the correct answer is option A.

Question 10
1 / -0

Natural fixation of nitrogen takes place through a non-biological process called ___________.

A
artificial fixation

B
nitrogen fixation by lightening

C
industrial fixation

D
synthetic fixation

Solution

In non biological fixation of nitrogen when the plant dies the fixed nitrogen is released making it available to other plants and this helps to fertilize the soil. The great majority of legumes have this association but a few genera do not. In farming practices fields are rotated through various crops like clover and buckwheat which are known as green manure.
