Hint: (i), (iii) & (iv) are correct. In outcrossing
animals are mated within the same breed, but

of their pedigree upto 4 – 6 generations. In
outbreeding there is breeding of unrelated
animals which may be between individuals of
the same breed (but having no common
ancestors), or between different breeds or
different species.

Hint: (iii) is wrong. Trichoderma are free living
fungi.

Hint: Type I and Type II restriction
endonucleases are not used in recombinant
DNA technology as they cut DNA at random
sites. Restriction endonucleases cut DNA
strands at specific points in their sugar
phosphate back bones. In Hind II restriction
endonuclease H stands for Haemophilus and
in stands for influenza.
10. (a)
Hint: (ii) is wrong. Most Bt toxins are insect
group specific.

17. (b)
Hint: Gracilaria (Red alga), Fucus (Brown alga)
are the only two.

not aquatic
Polytrichum (Moss) – not thalloid, not aquatic
18. (b)
Hint:
(i) Although this statement,”live in harsh
habitats”is mentioned for Archaebacteria
in NCERT,but we cannot ignore the fact
that Cyanobacteria can live in all kinds of
habitats with some species even in harsh
habitats.So we consider this statement
True for Cyanobacteria also.
(ii) False, Archaebacteria live in ruminant gut
(iii) False, chlorophyll ‘a’ is abundant in them
(iv) True
20. (a)
Hint: (i) False, shows radial symmetry in adults

(iii) True
(iv) False, complete digestive system
24. (a)
Hint: Only (iii) is not true.

Hint: Only (iii) is wrong. The process of muscle
contraction is slower in smooth muscle as
they have a poor formed SR.

segments).
(c) Caecae are in the intestine on 26th segment.
(d) Typhlosole is in the intestine b/t 26 – 35
segments.
28. (a)
Hint: (i), (iii), (iv) are incorrect. Only (ii) is
correct.
(i) ‘Porins’ form huge pores.
(iii) Lipid solubility increases rate of
diffusion
(iv) They have eight different types of
“Aquaporins”
29. (b)
Hint: Sulphur, Potassium & phosphorus are

Hint: Only (i) is correct.
36. (a)
Hint:
(i) Wrong – Intercarpal is gliding joint
(ii) Correct

(iv) Wrong – White fibres have few
mitochondria & abundant sarcoplasmic
reticulum
38. (b)
Hint: (i) Correct
(ii) Correct
(iii) PTH – Ca+2 metabolism, therefore, False.
(iv) Vasopressin is synthesised in the
hypothalamus, therefore, False.
39. (a)

Hint: ‘FOAM’ stands for Friends of the Arcata
Marsh which are responsible for an Integrated
waste water treatment project.
42. (a)
Hint: Only (i) is correct.
(ii) False; male is smaller than female.
(iii) False; takes two weeks.
(iv) False; Single mating produces many
progeny.
56. (b)
Hint: In liverworts, rhizoids are unicellular.
58. (c)
Hint: Clostridium botulinum is obligate
anaerobe. Xanthomonas oryzae causes
bacterial blight of rice. Citrus canker is
caused by Xanthomonas citri.

50. (d)
Hint: Taken line straight from NCERT.
51. (c)
Hint: Population has Age distribution and
individual has Age.

53. (a)
Hint: Only (iii) is correct.
(i) False; Animals more than plants
(ii) He says it is 7 million
