Q1. Amniocentesis for sex determination is legally banned to
Answer : Option C
Explaination / Solution:
Amniocentesis is a test to known chromosomal pattern of embryo that can reveals the sex of foetus. Large number of female foetus is aborted after knowing the sex of foetus. So it is illegal to check sex of foeticide.

Oleum is pyrosulphuric acid (H2S2O7 )
Q8. For rolling motion without slipping the kinetic energy of the body is
Answer : Option D
Explaination / Solution:
Rolling motion without slipping involve both translation motion and rotation motion. Hence kinetic energy of body in rolling motion is the sum of both translation kinetic energy and rotational kinetic energy.
Q9. The coefficient of viscosity for a fluid is defined as the ratio of
Answer : Option D
Explaination / Solution:
The degree to which a fluid resists flow under an applied force, expressed as the ratio of the shearing stress to the velocity gradient. The coefficient of viscosity of liquids decreases as temperature increases because the bonds between molecules are weakened.
Q10. A concept fundamental to understanding water movement is called
Answer : Option A
Explaination / Solution:
Plant-water relations, an understanding of certainstandard terms is necessary. Water potential is a concept fundamental to understand water movement. Solute potential and pressure potential are the two main components that determine water potential.
