Question 1
1 / -0

Canabis sativa is the source of

A
Opium

B
LSD

C
Marijuana

D
Cocaine

Solution

Cannabis sativa is a species of plant from the family cannabaceae. It is a psychoactive drug that can be used for medicinal or recreational purpose. So, the correct option is 'marijuana'.
Question 2
1 / -0

HIV selectively targets.

A
B - memory cells

B
B - effector cells

C
T - cytotoxic cells

D
T - helper cells

Solution

HIV multiplies in macrophages and then new viruses targets T - helper cells which makes the infected person immuno - deficient . So the correct option is "T- helper cells"
Question 3

How many statements given below is/are wrong?

A. With repeated use of drugs, the tolerance level of the receptors present in our body decreases.
B. Smoking increases carbon monoxide (CO) content in the blood and reduces the concentration of heme bound oxygen.
C. Smack is chemically diacetylmorphine.
D. the plant illustrated is Atropa belladonna and has hallucinogenic properties.

A
One

B
Two

C
Three

D
Four

Solution

The deadly nightshade (Atropa Belladonna), a plant hallowed by long tradition as one of the classic poisons of antiquity. The species belladonna is considered a vital tool in the study of the autonomic nervous system leading to the identification of acetylcholine as an important neurotransmitter in mammals. The symptoms of belladonna poisoning include hallucinogenic properties, Whereas smack is known as heroin.
So the correct option is 'Two'.
Question 4
1 / -0

Which of the following statements is not true for cancer cells in relation to mutations?

A
Mutations destroy telomerase inhibitor

B
Mutations inactivate the cell control

C
Mutations inhibit production of telomerase

D
Mutations in proto-oncogenes accelerate the cell cycle
Solution
Correct Answer: C
Explanation:
Mutation in genes that regulate cell proliferation, cell differentiation, and cell division brings about oncogenic transformation, normal cells to cancer cells.
The changed or mutated genes are called oncogenes and the unchanged related genes are called proto-oncogenes.
These proto-oncogenes help in cell growth and mutation in these leads to uncontrolled growth.
Cancer cells undergo repeated cell division, cell death is inhibited in them, due to the presence of telomeres.
Cancer cells activate an enzyme known as telomerase that prevents the DNA to get shortened, by adding genetic units onto the telomeres(end of the chromosome).
Telomerase is silenced in most of the normal cells due to the presence of telomerase inhibitors, but it is active in most cancer cells, due to destroying of telomerase inhibitors which causes their immortality.
Hence, the correct answer is Mutation inhibit production of telomerase.
Question 5
1 / -0

Auto immune disorder affecting neuromuscular junction leading to fatigue, weakening and paralysis of skeletal muscle is _____.

A
Muscular dystrophy

B
Tetany

C
Gout

D
Myasthenia gravis
Solution
- Muscular dystrophy is a disease characterized by progressive degeneration of muscle fibers without the involvement nervous system. It has a hereditary origin.
- Tetany is overly stimulated nerve which causes involuntary muscle cramps and contractions. it caused by low level of calcium.
- Gout is caused by two conditions one due to excessive formation of uric acid second by the inability to excrete it. Uric acid gets deposited in the joints as monosodium salts.
- Myasthenia gravis is an autoimmune disease of neuromuscular junction caused by antibodies to cholinergic receptors. it is characterized by grave weakness of the muscles due to the inability of neuromuscular junctions to transmit impulses from nerve to the muscle.
Thus the correct answer is option D.
Question 6
1 / -0

Germ or germ-substance introduced into the body to prevent the occurrence of an infectious disease is known as

A
Vaccine

B
Toxoids

C
Cytokine

D
None of these

Solution

The germ of germ-substance introduced into the body to prevent the occurrence of an infectious disease is known as the vaccine. It provides active acquired immunity to a particular disease.
So, the correct answer is 'Vaccine'.
Question 7
1 / -0

Diseases are broadly grouped into infection and non-infectious diseases. In the list given below, identify infectious diseases.
I. Cancer
II. Influenza
III. Allergy
IV. Smallpox

A
I and II

B
II and II

C
III and IV

D
II and IV
Solution
Cancer is a genetic and noninfectious disease
Influenza is a viral infection caused by the Influenza virus. It is commonly known as Flu and is a highly contagious disease. It spreads by direct contact, by using the articles used by the infected person, and also by droplets.
Allergies are also non-infectious.
Smallpox is caused by the Variola virus. It is a highly contagious disease with no cure. Smallpox has been eradicated completely owing to the massive vaccination campaigns across countries.
So, the correct answer is, 'Influenza' and 'Small Pox'.
Question 8
1 / -0

Elephantiasis is cause by

A
W. Bancrofti

B
P. Vivax

C
Bedbug

D
Elephant

Solution

Elephantiasis is caused by Wuchereria bancrofti, which a nematode. It is also called lymphoid filariasis. They infect the lymph nodes of and produce many microfilariae. Because of this, the lymph nodes swell up and the limbs appear like a foot of the elephant.
Hence, the correct answer is W. bancrofti.
Question 9
1 / -0

BCG vaccination is to be given to a new born child

A
Immediately after child birth

B
Within 48 hours

C
Within seven days

D
Within six month

Solution

These are the antigenic substance produced from the causative agent of disease, which helps in providing immunity against one or more disease. BCG stands for Bacille Calmette Guerin, is the vaccine provided against the disease tuberculosis (TB). It is given to 6 months old babies.

Therefore the right answer is option "D".
Question 10
1 / -0

Filaria belongs to

A
Arthropoda

B
Nematoda

C
Chordate

D
Mollusca

Solution

Filaria belongs to the phylum Nematoda. They are parasitic and cause the disease called filariasis. For example, Wuchereria bancrofti .
Hence, the correct answer is 'Nematoda'
