(viii) female $QRSKHOHV mosquito
(ix) human beings (x) quinine - (a) 15. (b) 16. (b) 17. (c) 18. (b)
- (a) A-Antigen, B-Binding sites, C-Epitopes, D-Antibody
(b) Each antibody molecule has at least two binding sites (B)
that can recognise and attach to the specific epitopes on
an antigen.
(c) After the binding of antigen with antibody, an antigen-
antibody complex is formed. This complex is then
transported to cellular system where it can be destroyed
or deactivated.
(d) Antigen - A, B and AB
- (a) Morphine
(b) Morphine is the active principal alkaloid of opium. It is
obtained from the latex of 3DSDYHUVRPQLIHUXP.
(c) Morphine has strong analgesic effect as it can bind to
specific receptors in central nervous system and relieves
pain. It also depresses respiratory centre and contributes
to the fall in blood pressure. It can cause bradycardia.
(d) C 17 H 19 NO 3

(iii) hexagonal (iv) comb foundation
(v) super (vi) gravid
(vii) centrifuged - (a) 15. (b) 16. (a) 17. (c) 18. (a)
- (a) A-Agar medium, B-Callus, C-Suspension culture,
D-Cell clumps
(b) Callus is irregular, unorganised and undifferentiated mass
of actively dividing cells.
(c) If tissue cultures are kept in the same culture vessel, they
die in course of time due to depletion of nutrients from
the media. Therefore, regular transfer into new culture
vessels is necessary.
(d) Auxin (2, 4-D)- (a) Stage A - Follicular maturation and superovulation
Stage D - Embryos are transferred to surrogate mother
(b) B - 6-8, C - 8-32
(c) Multiple Ovulation Embryo Transfer Technology (MOET)
(d) MOET is a controlled breeding programme for herd size
improvement in a short time. This technology has been
demonstrated for cattle, sheep, rabbits, buffaloes, mares,
etc.

- (i) manufacturing unit (ii) scaling up
(iii) glass vessel (iv) bioreactor
(v) support (vi) suspended
(vii) column - (a) 15. (c) 16. (a) 17. (b) 18. (b)
- (a) The given firure is of anaerobic sludge digester.
(b) A-Sludge inlet, B-Sludge, C-Spent sludge, D-Methane vent
(c) Spent sludge from the anaerobic sludge digester can be
used as manure or part of compost.
(d) Methanogenic bacteria digest the activated sludge and
produce marsh gas which is a mixture of methane, H 2 S
and CO 2. - (a) A-Soluble compounds or monomers, B-Fermentative
microbes, C-Methane, D-CO 2
(b) C - 50-70%, D - 30-40%
(c) Another name of biogas is gobar gas. Biogas provides
both storable form of energy and manure. It does not add
to pollution. It minimises the chances of spread of faecal
pathogens.
