Q3. How much percent of vacuoles occupy the volume of the cell in plant cells?
Answer : Option A
Explaination / Solution:
In a mature cell, the vacuole may occupy as much as 90 percent of the cell volume, such that the rest of the cell contents are flattened against the cell membrane.
Q4. Which sampling is also known as Judgment sampling
Answer : Option A

Q5. Development that meets the need of the present generation without compromising the ability of the future generation to meet their own needs
Answer : Option C
Explaination / Solution:
The concept of sustainable development was emphasised by the United Nations Conference on Environment and Development (UNCED), which defined it as: ‘Development that meets the need of the present generation without compromising the ability of the future generation to meet their own needs’.
Q6. A DNA segment which serves as a kind of “ON-OFF switch” for transcription is a/an
Answer : Option A
Explaination / Solution:
An operator is a segment of DNA to which a transcription factor binds to regulate gene expression by repressing it. The protein that does this is called a repressor. Repressors bind to operators to prevent transcription.
The main operator (O2) in the classically defined lac operon is located slightly downstream of the promoter. Two additional operators, O1 and O3 are located at -82 and +412, respectively. Operator attach with template strand to initiate transcription process.
Q7. You have a special light bulb with a very delicate wire filament. The wire will break if the current in it ever exceeds 1.50 A, even for an instant. What is the largest root-mean-square current you can run through this bulb?
Answer : Option D
Explaination / Solution:
maximum value of current
root-mean-square current
Q8. The wire of the potentiometer has resistance 4 ohms and length 1 m. It is connected to a cell of e.m.f. 2 volts and internal resistance 1 ohm. The current flowing in the potentiometer is:
Answer : Option B
Explaination / Solution:
If the battery has an e.m.f E, resitance of the potentiometer is R and the internal resistance of the battery is r, then the current I flowing in the potentiometer wire is given as
Q9. For all practical purposes, the motion of a simple pendulum is SHM,
Answer : Option D
Explaination / Solution:
No Explaination.
Q10. Metal hydrides are ionic, covalent or molecular in nature. Among LiH, NaH, KH, RbH, CsH, the correct order of increasing ionic character is
Answer : Option B
Explaination / Solution:
As the size of cation increases ionic character also increases.
