Q:

Which one of the following is not a biosphere reserve of India?

A) Agasthyamalai B) Nokrek
C) Great Nicobar D) Great Himalayan
 
Answer & Explanation Answer: D) Great Himalayan

Explanation:

Biosphere Reserves are established for the conservation of biodiversity for economic and social development  and  maintenance  of associated  cultural  values.There are  18  Biosphere  Reserves  in  the country.  Agasthyamala  Biosphere reserve is located at the southern-most  part  of  the  Western  Ghats and spread over two states,Kerala and Tamil Nadu. It was established in 2001;Nokrek Biosphere Reserve is  a  national  park  situated  in  West Garo  Hills  district  of  Meghalaya. UNESCO   made   it   the   Biosphere Reserves  in  May  2009;The  Great Nicobar   Biosphere   Reserve   has such    ecosystems    that    include tropical   wet   evergreen   forests, mountain    ranges    and    coastal plains. The region is well known for its rich biodiversity. It was made a biosphere reserve in January 1989; while  The  Great  Himalayan  is  a National   Park   situated   in   Kullu region  of  Himachal  Pradesh.  The park was established in 198

Q:

A  photon  of  X-ray  has  energy  of  1  keV.  A photon of visible radiation has energy of 3 eV.  In  this  context,  which  one  of  the following statements is not correct?

A) The wavelength of X-ray photon is less than the wavelength of visible radiation photon. B) Both    the    photons    have    different energies.
C) The  speeds  of  both  the  photons  in vacuum are different D) The   frequency   of   X-ray   photon   is higher  than  the  frequency  of  visible radiation photon.
 
Answer & Explanation Answer: C) The  speeds  of  both  the  photons  in vacuum are different

Explanation:

The speed of all the electromagnetic radiation are always   same   and   equal   to   the numerical value 3 x 10^8m/sec.

Q:

A parallel-plate capacitor of capacitance C1is  made  using  two  gold  plates.  Another parallel-plate capacitor of capacitance C2is made  using  two  aluminium  plates  with same  plate  separation,  and  all  the  four plates  are  of  same  area.  If gand aPare respectively  the  electrical  resistivities  of gold and aluminium, then which one of the following relations is correct?

A) C1>C2 B) C2>C1
C) C1pa = C2pg D) C1 = C2
 
Answer & Explanation Answer: D) C1 = C2

Explanation:

C1= capacitance of gold plates

C2=   capacitance   of   aluminium plates

rg= Gold’s resistivity

ra= Aluminium’s resistivity

As the capacitance depends on the shape,  size  &  geometrical  placing of  the  conductors  &  the  medium between them, hence, the value of capacitance  will  be  independent  of resistivity. Therefore, C1= C2

Q:

Consider the electromagnetic radiations having wavelengths 200 nm, 500 nm and 1000 nm. Which wavelength (s) of the following can make visual sensation to a human eye?

A) 200 nm and 500 nm B) 500 nm and 1000 nm
C) 500 nm only D) 200 nm and 1000 nm
 
Answer & Explanation Answer: C) 500 nm only

Explanation:
Visual image of human eye is 390-700 nanometer. So, approximate value is 500 nanometer only.

Q:

The plant growth regulators are small, simple molecules of diverse chemical composition. They are

A) carbohydrates, fats and proteins B) indole compounds, adenine derivatives, carotenoids and terpenes
C) fatty acids, glucose and vitamins D) vitamin C, vitamin D and glucose
 
Answer & Explanation Answer: B) indole compounds, adenine derivatives, carotenoids and terpenes

Explanation:

The  plant  growth  regulators  are small,  simple  molecules  of  diversechemical composition. They can be in   form   of   indole   compounds, adenine   derivatives,   carotenoids derivatives,terpenes  or  gases  like ethyleneetc.The   plant   growth regulators  are  bifurcated  into  two groups according to their functions in  a  living  plant  body.First  group of   plant   growth   regulators   are found   in   growth   activities,   for instance,  cell  division,  flowering, fruiting  and  seed  formation.The second   group   of   Plant   growth regulators   are   involved   in   plant responses  to  wounds  and  stresses of biotic and abiotic origin.

Q:

Kwashiorkor  disease  in  children  is  caused by

A) sufficient carbohydrates but less fats in diet B) sufficient  carbohydrates  and  fats  but deficient proteins in diet
C) sufficient  vitamins  but  deficient  fats  in diet D) sufficient  fats  but  deficient  vitamins  in diet
 
Answer & Explanation Answer: B) sufficient  carbohydrates  and  fats  but deficient proteins in diet

Explanation:

Kwashiorkar is produced by protein deficiency unaccompanied by calorie  deficiency.  It  results  from the  replacement  of  mother’s  milk by a high calorie-low protein diet in a child more than one year in age. Like marasmus, kwashiorkor shows wasting   of   muscles,   thinning   of limbs,  failure  of  growth  and  brain development
