Question 1
1 / -0

The infective stage of Ancylostoma duodenale to humans is

A
Egg containing larva

B
Filariform larva

C
Microfilaria larva

D
Rhabditiform larva

Solution

The infective stage of Ancylostoma duodenale to humans is known as filariform larva. This form generally enters the body of host either by swallowing or by burrowing into the skin through hair follicles. Upon reaching the small intestine, the larvae molts fourth and the last time to develop into a mature worm.
Question 2
1 / -0

The most common confirmatory test used to diagnose AIDS is

A
ELISA

B
Western blot

C
PCR

D
None of the above

Solution

ELISA (enzyme-linked immunosorbent assay) is used to detect HIV infection. ELISA is the preliminary test in the diagnosis of AIDS. If ELISA test is positive, the Western blot test is usually administered to confirm the diagnosis.
Therefore, the correct answer is option B.
Question 3
1 / -0

Iron deficiency anaemia is a complication of which parasitic infection?

A
Roundworm

B
Threadworm

C
Hookworm

D
Whipworm

Solution

Hookworm infection may be associated with a skin reaction (dermatitis), an increase of eosinophils, a pulmonary reaction (pneumonitis), and skin rash. Gastrointestinal symptoms include mild abdominal pain, nausea, vomiting, and anorexia. iron-deficiency anemia is due to the blood loos often associated with hookworm infection.
Thus, the correct answer is option (C), 'Hook worm'.
Question 4
1 / -0

'Cutaneous larva migrants' is due to

A
$$Ancyclostoma$$ $$braziliense$$

B
$$Ascaris$$ $$lumbricoides$$

C
$$Dracunculus$$

D
All of the above

Solution

'Cutaneous larva migrants' is a skin disease in humans, caused by the larvae of various nematode parasites of the hookworm family (Ancylostomatidae). The most common species causing this disease is Ancyclostoma braziliense.
Therefore, the correct answer is option A.
Question 5
1 / -0

In heavy smokers, the alveoli of the lungs are enlarged and damaged reducing the surface area for the exchange of respiratory gases. This condition is called:

A
Asthma

B
Silicosis

C
Emphysema

D
Anosmia

Solution

Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively shorter of breath. In emphysema, the inner walls of the air sacs weaken and eventually rupture - creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches the bloodstream.
Thus, the correct answer is option (C), 'Emphysema'.
Question 6
1 / -0

The term 'Oncogene' is associated with

A
Genetic engineering

B
Tissue culture

C
Gene library

D
Cancer

Solution

An oncogene is a gene that when mutated or expressed at abnormally high levels contribute to converting a normal cell into a cancer cell. Cancer cells are cells that are engaged in uncontrolled mitosis.
Question 7
1 / -0

At present, animal cell culture technology is extensively used for the production of

A
Chylomicrons

B
Antibiotics

C
Vaccines

D
Edible proteins

Solution

The animal cell lines are cultured in the laboratory on the artificial media which requires a specific temperature. Biological products produced by recombinant DNA (rDNA) technology in animal cell cultures include enzymes, synthetic hormones, immunobiological (monoclonal antibodies, interleukins, lymphokines), and anticancer agents.
So, the correct answer is option C.
Question 8
1 / -0

The tobacco protein induced arteriosclerotic disease is

A
Aneurysm

B
Polyarteritis nodosa

C
Thromboangiitis obliterans

D
DVT

Solution

Thromboangiitis obliterans, also called Buerger disease is a rare disease caused by small blood vessels that become inflamed and swollen. The blood vessels, then narrow or become completely blocked by the blood clots (Thrombosis). Blood vessels of the hand and feet are especially affected. This condition mostly affects young men, ages, 20-40, who are heavy smokers or chew tobacco.
Thus, the correct answer is option (A), 'Thromboangiitis obliterans'
Question 9
1 / -0

Why foods derived from genetically modified crops required to be tested for possible allergic reactions in people?

A
They may cause allergies due to release of new kind of proteins.

B
They may not be digested.

C
They may cause more hunger.

D
All of the above.

Solution

The process of creating a GM crop can produce many changes in the natural functioning of the plant's genome. Native genes can be mutated, deleted, permanently turned on or off and may change their levels of protein expression. This increasing the levels of an existing protein or even producing a completely new and unknown protein within the crop can act as an allergen in consumers. Hence, foods derived from genetically modified crops are required to be tested for possible allergic reactions in people.
Question 10
1 / -0

Which of the following vaccine is related with tissue culture?

A
Chicken pox

B
Hepatitis B

C
Anti-rabies

D
Measles

Solution

Cell culture vaccines are mainly produced by culture of mammalian cell lines. These are more affordable and produced in large quantities. Moreover, cell lines can be grown in synthetic media avoiding animal serum.
So, the correct answer is option C.
