Q1. The policy of Great Leap Forward (GLF) was announced in
Answer : Option B
Explaination / Solution:

The GLF campaign intitiated in 1958 aimed at industrialising the country on a massive scale.

Q2. Adiabatic wall is –
Answer : Option B
Explaination / Solution:

In thermodynamics, an adiabatic wall between two thermodynamic systems does not allow heat or matter to pass across it. In theoretical investigations, it is sometimes assumed that one of the two systems is the surroundings of the other.

Q3. Electric charges are of
Answer : Option C
Explaination / Solution:

Two types

  • Positivecharge—deficiency of electrons i.e. if a body loses electrons it will be positive charged.
  • Negative charge—excess of electrons i.e. if a body gains electrons it will be negative charged

Q4. When a solid is deformed,
Answer : Option A
Explaination / Solution:

External force permanently distubed the equilibrium position of the interatomic ( or intermolecular ) forces between the particles of solid bodies.

Q5. Brief exposure of cells to an electric field also allow the bacteria to take up DNA and this process is called as
Answer : Option B
Explaination / Solution:

Electroporation, or electropermeabilization, is a microbiology technique in which an electrical field is applied to cells in order to increase the permeability of the cell membrane, allowing chemicals, drugs, or DNA to be introduced into the cell.

Q6. Urinary bladder is absent in :
Answer : Option D
Explaination / Solution:

Urinary bladder is absent in snake and bird because the urine of these is semi-solid consisting mainly of uric acid. The primary function of urinary bladder is to store urine in mammals. The urinary bladder cannot store semi-solid urine.

Q7.   (vap). This equation best illustrates the
Answer : Option D
Explaination / Solution:

The number of water molecules from the gaseous state into the liquid state also increases till the equilibrium is attained i.e., rate of evaporation = rate of condensation At equilibrium the pressure exerted by the water molecules at a given temperature remains constant and is called the equilibrium.

Q8. Fossils are most commonly preserved in
Answer : Option B
Explaination / Solution:

Fossils are dead remains of plants and animals buried inside the earth crust millions of year ago. Fossils are commonly preserved in sedimentary rock as this kinds of rocks are formed layer by layer in course of time.

Q9. Which of the following statements about Hydrogen bond incorrect?
Answer : Option C
Explaination / Solution:

Hydrogen atom covalently bonded to highly electronegative atom such as N,O experience electrostatic field of another highly electronegative atom due to which a partial positive charge is developed on H atom.

Q10. The following amine can be classified as (C2H5)2NH
Answer : Option B
Explaination / Solution:

Nitrogen is attached is two carbons, so this is asecondary amine.
