Q1. C.D- R.O.M. is a
Answer : Option C
Explaination / Solution:
No Explaination.
Q2. What is the oxidation state of K in
Answer : Option C
Explaination / Solution:
K has +1 oxidation state. "The potassium atom losses one electron when forming compound as it has one electron on it's valence shell".
Q3. Amplification is the
Answer : Option C
Explaination / Solution:
It is the process of increasing the amplitude and hence the strength of an elctrical signal by using an electric circuit having atleat on transistor is called amplifier.Amplification is rerquired to compensate for the loss of strenght of a signal during its transmission.The additional energy is otianed from a dc source.The process of amplification is done at a location betwen the sources and the destination where the strength of signal becomes weaker than the required level.
Q4. MPC+MPS should always be equal to 1
Answer : Option A
Explaination / Solution:
No Explaination.
Q5. What is meant by commercialisation of agriculture?
Answer : Option C
Explaination / Solution:
By commercialisation of agriculture we mean production of agricultural crops for sale in the market, rather than for family consumption.
Q6. The radioactive isotope used in determining the age of organic substances is
Answer : Option A
Explaination / Solution:
The ratio of Carbon -12 to Carbon-14 at the moment of death is the same as every other living thing., but Carbon-14 decays and is not replaced. The carbon-14 decays with its half-life of 5770 years., while the amount of Carbon-12 remains constant in the sample. By looking at the ratio of Carbon-12 to Carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely.
Q7. One dimensional diagram is:
Answer : Option A
Explaination / Solution:
In line diagrams, only one line passes through a vertex therefore it is a one dimensional diagram.
Q8. How many meiotic divisions are required to form 64 pollen grains
Answer : Option A
Explaination / Solution:
Each microspore mother cell produces four pollen grains by reduction division. Hence to produce 64 pollen grains 16 meiotic or reduction division is required.
Q9. NABARD stands for
Answer : Option C
Explaination / Solution:
NABARD Serves as an apex financing agency for the institutions providing investment and production credit for promoting the various developmental activities in rural areas
Q10. Multinucleate condition arise when Cytokinesis does not follow karyokinesis, this type of cells are called as
Answer : Option D
Explaination / Solution:
Karyokinesis is followed by cytokinesis but some times cytokinesis is not followed by karyokinesis which leads to the establishment of multinucleate condition. This type of cells are called as coenocytes.
