Q.1)Vital capacity of lung is _________.
> (1) IRV + ERV + TV - RV
> (2) IRV + ERV + TV
> (3) IRV + ERV
> (4) IRV + ERV + TV + RV
solution:
> Option (2) is the correct answer because vital capacity is the
maximum volume of air a person can breathe in a
er forced
expiration. This includes ERV, TV and IRV.
Q.2) Match List I with List II.
A. P-wave. I. Beginning of systole
B. Q-wave. II. Repolarisation of ventricles
C. QRS complex. III. Depolarisation of atria
D. T-wave IV. Depolarisation of ventricles
Choose the correct answer from the options given
below :
> 1) A-II, B-IV, C- I, D-III
> 2) A-I, B-II, C-III, D-IV
> (3) A-III, B-I, C-IV, D-II
> (4) A-IV, B-III, C-II, D-I
solution:
> The correct answer is option (3) as in a standard ECG, P-wave
represents the electrical excitation (or depolarisation) of the atria
which leads to the contraction of both the atria.
> QRS complex represents the depolarisation of ventricles which
initiates the ventricular contraction.
> T-wave represents the return of the ventricles from excited to normal
state.
Q.3)Match List I with List II
A. Vasectomy. I. Oral method
B. Coitus interruptus. II. Barrier method

Choose the correct answer from the options given
below
> A-II, B-III, C-I, D-IV. (2) A-IV, B-II, C-I, D-III
> (3) A-III, B-I, C-IV, D-II. (4) A-III, B-IV, C-II, DI-
solution:
> Option (4) the correct answer because
> (i) Vasectomy is a surgical method of contraception
> (ii) Coitus interruptus is a natural method of contraception
> (iii) Cervical cap is a barrier method of contraception
> (iv) Saheli is an oral method of contraception which is a non-steroidal
pill
Q.4) Match the following :
A. Peptic cells. I. Mucus
B. Goblet cells. II. Bile juice
C. Oxyntic cells. III. Proenzyme pepsinogen
D. Hepatic cells. IV. HCl and intrinsic factor for
. absorption of vitamin B12
> (1) A- III, B- I, C- IV, D -II
> (2) A-II, B-IV, C-I, D-III
> (3) A-IV, B-III, C-II, D-I
> (4) A-II, B-I, C-III, D-IV
solution:
> Option (1) is the correct answer because gastric glands have three
major types of cells namely
> (i) Mucus neck cells which secrete mucus
> (ii) Peptic or chief cells which secrete the proenzyme pepsinogen
> (iii) Parietal or oxyntic cells which secrete HCl and intrinsic factor for
absorption of vitamin B12.
Q.5) Which one of the following common
sexually transmitted diseases is completely
curable when detected early and treated
properly?
> (1)Hepatitis-B
> (2) HIV Infection
> (3) Genital herpes
> (4) Gonorrhoea
solution:
> The correct answer is option (4) because except for hepatitis-B, genital
herpes and HIV infection other STIs are completely curable if detected
early and treated properly.
> Gonorrhoea is a bacterial disease which can be treated and cured
completely, other diseases mentioned are viral diseases.
Q.6) Which of the following is not a cloning
vector?
> (1) pBR322
> (2) Probe
> (3) BAC
> (4) YAC
solution:
> Option (2) is correct answer because a single stranded DNA or RNA
tagged with a radioactive molecule is called a probe and it helps in the
detection of mutated gene.
> Option (1), (3) and (4) are not correct because YAC, BAC, pBR322 are
vectors.
Q.7) Match the following
> (Interacting species)
> A. A Leopard and a Lion in a forest/
grassland
> B. A cuckoo laying eggs in crow's
nest
> C. Fungi and root of a higher plant in
Mycorrhizae
> D. A cattle egret and a Cattle in a
field
> (Name of interaction)
> I. Competition
> II. Brood parasitism
> III. Mutualism
> IV. Commensalism
> Choose the correct answer from the options given below.
> (1) A-III, B-IV, C-I, D-II
> (2) A-II, B-III, C-I, D-IV
> (3) A-I, B-II, C-III, D-IV
> (4) A-I, B-II, C-IV, D-III
solution
> Answer(3)
> Sol. A leopard and a lion in a forest/grassland exemplify competition where both the species
are competing forthe same resources.egg in the nest of crow (host bird).
> Fungi and root of a higher plant in mycorrhizae exemplify mutualism where both the species
are benefitted. The fungi help the plant in the absorption of essential nutrients from the soil
while the plant in turn provides the fungi with energy yielding carbohydrates.
> A cattle egret and a cattle in a field exemplify commensalism where one species benefits and
the otherremains unaffected.
> The egrets always forage close to where cattle are grazing because the cattle, as they move,
stir up and flush out insects from the vegetation that otherwise might be difficult forthe egrets
to find and catch.
Q.8)Which one of the following techniques
does not serve the purpose of early diagnosis
of a disease for its early treatment?
> (1) Polymerase Chain Reaction (PCR) technique
> (2) Enzyme Linked Immuno-Sorbent Assay (ELISA) technique
> (3) Recombinant DNA Technology
> (4) Serum and Urine analysis
solution
> The correct answer is option (4) because using conventional methods
of diagnosis like serum and urine analysis, etc, do not help in early
diagnosis. Recombinant DNA technology, Polymerase Chain
> Reaction [PCR] and Enzyme Linked Immuno-Sorbent Assay (ELISA) are
some of the techniques that serve the purpose of early diagnosis.
Q.9) Which of the following is correct ?
> (1)Presence of large amount of nutrients in water restrìct algal bloom
> (2)Algal Bloom decreases fish mortality
> (3) Eutrophication refers to increase in domestic sewage and waste
water in lakes.
> (4) Biomagnification refers to increase in concentration of the toxicant
at successive trophic levels.
solution
> Increase in the concentration of the toxicant at successive trophic level
is called biomagnification.
> Large amount of nutrients in water promotes growth of algal bloom.
Algal bloom increases fish mortality.
> Eutrophication refers to the natural aging of a lake by nutrient
enrichment of its water.
Q.10) Match List I with List II. List I List II
A. CCK. I. Kidney
B. GIP. II. Heart
C. ANF. III. Gastric gland
D. ADH. IV. Pancreas
> (1) A-II, B- IV, C- I, D-III
> (2) A-IV, B-II, C-III, D-I
> (3) A-IV, B-III, C-II, D-I
> (4) A-III, B-II, C-IV, D-I
solution
> The correct answer is option (3) as
> Cholecystokinin (CCK) acts on both gall bladder and pancreas and
stimulates the secretion of bile juice and pancreatic enzymes
respectively.
> GIP inhibits gastric secretion and motility.
> Atrial Natriuretic Factor (ANF) is released from the atrial wall of our
heart.
> Anti-diuretic hormone (ADH) acts mainly on the kidney and stimulates
resorption of water and electrolytes by the distal tubules
