Q3. The molar specific heat at constant volume, for monatomic gases is
Answer : Option B
Explaination / Solution:
for monatomic gases f = 3
Q4. The basic assumption regarding resources while drawing a PPC is
Answer : Option B
Explaination / Solution:
Since human wants are unlimited and the means to satisfy them are limited, every society is faced with the fundamental problem of choosing and allocating its scarce resources among alternative uses. The production possibility curve or frontier is an analytical tool which is used to illustrate and explain this problem of choice.
Q5. Exponential growth pattern in a population results into
Answer : Option D
Explaination / Solution:
Exponential growth pattern in population results into j-shaped curve. During exponential growth faster growth occurs and j-shaped curve is formed when time v/s growth is drawn.

Q9. Where memory cells are formed?
Answer : Option D
Explaination / Solution:
Memory cells are formed in lymphocytes of WBC. Immunization against the particular disease based on the function of memory cell induced due to mild, heat killed pathogen administrated during immunization.
Q10. According to the Heisenberg uncertainty principle, in dealing with milligram-sized or heavier objects,
Answer : Option C
Explaination / Solution:
The effect of Heisenberg uncertainty principle is significant only for motion of microscopic objects, it is negligible in case of macroscopic objects. For example, we apply the concept of uncertainty to an object of mass 1 milligram.
The value of is very small and insignificant in this case. Therefore, when we deal with heavier objects the associated uncertainties have no real consequences and can be neglected.
