Answer : Option C
Explaination / Solution:
NH3 is used in preparation of caprolactum. Caprolactam is an organic compound with the formula (CH2)5C(O)NH. It is used to make Nylon 6 fiber and plastics.
Q2. A and B are contiguous cells. A has OP=10 atm and TP= 7atm, B has OP=8atm, TP=3 atm, DPD= 5 atm. The result would be
Answer : Option D
Explaination / Solution:
Two cells close to each other are called contiguous cells. Movement of water from one cell to other depends upon Diffusiion pressure deficit (DPD). DPD depends upon osmotic pressure and water pressure. So, movement of water from A to B will take place.
Q3. According to Pascal’s law for transmission of fluid pressure external pressure applied on any part of a fluid contained in a vessel is ___________________ in all directions
Answer : Option A
Explaination / Solution:
Pascal's principle is defined as a change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.
This principle is stated mathematically as:
is the hydrostatic pressure (given in pascals in the SI system), or the difference in pressure at two points within a fluid column, due to the weight of the fluid.
Q4. The molar heat capacity of a substance is the
Answer : Option C
Explaination / Solution:
The molar heat capacity of a substance is the quantity of heat needed to raise the temperature of one mole by one degree Celsius.
Q5. What makes up more than one-half the volume of neural tissue in our body?
Answer : Option A
Explaination / Solution:
The neuroglial cells which constitute the rest of the neural system protect and support neurons. Neuroglia makes up more than one-half the volume of neural tissue in our body.
Q6. Which system of classification was developed during Linnaeus time?
Answer : Option B
Explaination / Solution:
In Linnaeus' time a Two Kingdom system of classification with Plantae and Animalia kingdoms was developed that included all plants and animals respectively. This system was used till very recently.
Q7. The measures taken under NEP are called
Answer : Option D
Explaination / Solution:
The measures taken under New Economic Policy (NEP) are called economic reforms as these policies sought to reform the Indian economy and remove the rigidities that had entered into the various segments of the economy.
Q8. If c = 0.8 and m = 0.3, the open economy multiplier will be
Answer : Option A
Explaination / Solution:
No Explaination.
Q9. The average of the squared deviations from the arithmetic mean is called the
Answer : Option B
Explaination / Solution:
Variance is the expectation of the squared deviation of a random variable from its mean. Informally, it measures how far a set of (random) numbers are spread out from their average value.The variance is the square of the standard deviation, the second central moment of a distribution, and the co variance of the random variable with itself.
Q10. Old people usually exhibit weaker immune power due to degeneration of
Answer : Option B
Explaination / Solution:
Thymus gland produces a hormone called thymosin which stimulates the T-cells. T-cells help in producing antibodies in the bodies. In older people weaker immune power is due to degeneration of thymus gland.
