Q1. As a ball rises the vertical component of its velocity
Answer : Option C
Explaination / Solution:
if a ball is thrown upward at an angle? The ball has a vertical and a horizontal component of velocity. The force of gravity is acting on it and its acceleration is in the downward direction. The vertical component of velocity is therefore changing. As the motion and acceleration is in opposite direction so vertical component of velocity decrease.
Q2. System under which people collectively cultivated land is known as
Answer : Option A
Explaination / Solution:
Under the commune system, the farmers were encouraged to cultivate land collectively and not individually.
Q3. Inter kinesis is followed by which type of cell division that helps in regeneration?
Answer : Option C
Explaination / Solution:
The stage between the two meiotic divisions is called interkinesis and is generally short lived. Interkinesis is followed by prophase II, a much simpler prophase than prophase I.
Q4. Flocculation value is expressed in terms of
Answer : Option A
Explaination / Solution:
Fact
Q5. A point charge of 2.0 μC is at the centre of a cubic Gaussian surface 9.0 cm on edge. What is the net electric flux through the surface?
Answer : Option A
Explaination / Solution:
ϕ=q∈0=2×10−68.85×10−12=2.26×105Nm2/C
Q6. A lead cube measures 6.00 cm on each side. The bottom face is held in place by very strong glue to a flat horizontal surface, while a horizontal force F is applied to the upper face parallel to one of the edges. How large must F be to cause the cube to deform by 0.250 mm? (Shear modulus of lead = 0.6 Pa)
Answer : Option B
Explaination / Solution:
No Explaination.
Q7. Which of the following is used as selectable marker?
Answer : Option D
Explaination / Solution:
The Ampicillin resistance gene is used as selectable marker as it prevents the growth of non-transformants cells and promotes the growth of transformants only
Q8. Dev consumes large amount of alcohol and result is polyuria and dehydration due to :
Answer : Option B
Explaination / Solution:
Polyuria is usually the result of drinking excessive amounts of fluids (polydipsia), particularly water and fluids that contain caffeine or alcohol. Person suffering from polyuria may develop excessive production of urea and suffer from dehydration due to decrease in level of antiduretic hormone or vasopressin.
Q9.

Answer : Option A
Explaination / Solution:
Heat used in increasing temp
Q10. Vermiform appendix in man, nictitating membrane and wisdom teeth are
Answer : Option B
Explaination / Solution:
Vermiform appendix in man, nictitating membrane and wisdom teeth are vestigial organs of human beings. These organs are functional in our ancestors but in present human beings they have become functionless and only present as remain.
