C
Louis Pasteur

D
Stanely
Solution
- Vaccines are the suspension of the live or killed microorganism which mainly activates the immune response.
- Louis Pasteur produced the first vaccine for rabies by growing the virus in rabbits.
- Pasteur was the first scientist to artificially attenuate viruses for use in vaccines.
- He created several veterinary vaccines before his development of the rabies vaccine in 1885 for use in humans.
- So, the correct answer is option C.
Question 2
1 / -0

The process of attenuation was demonstrated by

A
Koch

B
Pasteur

C
Edward Jenner

D
None of the above

Solution

Attenuation is a process of injecting dead or weakened organisms of a particular disease into a healthy individual. So, as to create an active immunity against the infection.

So, the correct answer is 'Edward Jenner'
Question 3

A
BCG

B
DPT

C
MMR

D
STD

Solution

Their inactivation produces toxoids that are no longer toxic but maintain the antigenic property which is used as a vaccine.
So, the correct answer is option B.

Cinchona

B
Mango

C
Guava

D
Apple
Solution
- Malaria is caused by infection with unicellular eukaryotic parasites of the genus Plasmodium. The species Plasmodium falciparum is responsible for the most life-threatening malarial disease.
- Quinine extracted from the bark of the cinchona tree is used as an antimalarial agent.
- Hence, the cinchona tree is used to cure malaria.
- So, the correct answer is 'Cinchona'.
Question 5

Match the columns.

Column I Column II
a Palynology p Silkworms
b Oncology q Pollens
c Phycoloyg r Cancer
d Sericulture s Algae

A
a - s, b - r, c - q, d - p

B
a - q, b - r, c - s, d - p

C
a - s, b - q, c - r, d - p

D
a - r, b - q, c - s, d - p
Solution
- Palynology is the study of pollen grains and other spores, especially as found in archaeological or geological deposits. Pollen extracted from such deposits may be used for studying past climates and environments by identifying plants which are growing in a particular environment and climate.
- Oncology is a branch of medicine that deals with the prevention, diagnosis, and treatment of cancer. Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.
- Phycology or algology is a branch of life science and often is regarded as a subdiscipline of botany which involves the scientific study of algae. Algae are important as primary producers in aquatic ecosystems.
- Sericulture or silk farming is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, Bombyx mori (the caterpillar of the domesticated silk moth) is the most widely used and intensively studied silkworm.
So, the correct answer is 'B'.
Question 6
1 / -0

Question 8
1 / -0

The most mutable virus is

A
Chicken Pox Virus

B
$$HIV$$

C
Influenza Virus

D
Dengue Virus

Solution

Each generation of HIV (from each infected human cell) contains some percentage of variations, or mutations, from the parent virus, and HIV has much more than its proper share of such variations." In fact, it is the most mutable virus known." Until the discovery of this virus, it was commonly said that the influenza virus was the most mutable virus known because each generation changed its coat to some degree. HIV is highly mutable. Because of the virus' ability to rapidly respond to selective pressures imposed by the immune system, the population of the virus in an infected individual typically evolves so that it can evade the two major arms of the adaptive immune system; humoral (antibody mediated) and cellular (mediated by T cells) immunity.

So, the correct answer is 'HIV'.
