Question 3
1 / -0

Use the following information to answer the next question.

Doctors commonly prescribe antibiotics during bacterial infections. Penicillin is one such example. It is produced by fungi, which are microorganisms.

How does an antibiotic work?

A
It reduces body temperature

B
It kills fungi

C
It becomes a food resource for bacteria

D
It kills bacteria

Solution

An antibiotic is a drug that kills or prevents the growth of bacteria. It is not effective against infections caused by virus and fungi.

The correct answer is D.

Why alternatives A, B and C are wrong:

Antibiotics do not reduce body temperature; they do not become sources of food for bacteria, and they do not kill bacteria. Hence, alternatives A, B, and C are incorrect.
Question 4
1 / -0

Use the following information to answer the next question.

Diseases such as common cold that carry on for a ____i_____ are known as ____ii_____ diseases.

Acute diseases last for short periods of time. However, they spread rapidly in the body showing intense symptoms. Examples of acute diseases are cough, cold, influenza etc.

The correct answer is B.
Question 5
1 / -0

Use the following information to answer the next question.

Japanese Encephalitis is a vector-borne disease that transmits through the bite of mosquitoes.

Which of the following organs is mainly affected by this disease?

A
Lungs

B
Liver

C
Brain

D
Stomach

Solution

Japanese Encephalitis is a viral disease that transmits through the bite of mosquitoes. When the mosquito bites a healthy individual, the virus enters the blood stream and reaches the brain through the circulating blood.

The correct answer is C.

Question 6

1 / -0

Use the following information to answer the next question.

Diseases can be transmitted from one person to another by many means. A particular disease is transmitted through direct contact, but cannot be transmitted by hugging or shaking hand.

Which of the following diseases best suits the given mode of transmission?

Cholera

Syphilis

Kala-azar

Common cold

Solution

Some diseases such as syphilis and HIV-AIDS are transmitted by sexual contact from one person to another. They are known as sexually transmitted diseases (STDs).

However, STDs cannot be transmitted by casual physical contact such as hugging or shaking hands with the infected person.

The correct answer is B.

Why alternative A is wrong:

Cholera is a bacterial disease that transmits through contaminated water.

Why alternative C is wrong:

Kala-azar is a vector-transmitted disease that spreads when a sand fly bites a healthy individual after biting an infected individual.

Why alternative D is wrong:

Common cold is a viral disease that transmits from an affected individual to a normal individual through air.

Question 7
1 / -0

Use the following information to answer the next question.

Vaccines are small doses of a particular disease-causing microbe injected into the body of an individual. They act by fooling our immune system.

Which of the following statements is incorrect regarding the given information?

A
Vaccines prevent the occurrence of the disease.

B
Vaccines induce memory for the particular infection.

C
Vaccines block the entry of disease-causing microbes.

D
Vaccines mimic the action of the disease-causing microbe.

Solution

Vaccines contain small doses of particular disease-causing microbes. When injected into the body, they induce the immune system to develop memory against that particular microbe. Hence, when the next time the microbe enters our body, our immune system responds quickly.

The correct answer is C.
Question 8
1 / -0

Use the following information to answer the next question.

Penicillin was the first antibiotic to be discovered. It is effective against most bacterial disease, but is ineffective against fungal diseases.

Which of the following reasonscorrectly explains the given observation?

A
Fungal cells do not have a cell wall.

B
Bacteria are smaller in size when compared to fungi.

C
Fungal cells produce chemicals, which destroy penicillin.

D
Bacterial cells and fungi have dissimilar biochemical pathways.

Solution

Antibiotics act by blocking particular biochemical pathways in microbes. Pencilling targets the synthesis of cell wall in bacteria. Bacteria are unable to grow penicillin in the presence of penicillin and die easily. Penicillin is not effective against fungal cells since bacteria and fungi do not have similar biochemical pathways.

The correct answer is D.
