Q1. A level of expenditure at which minimum food needs are met is called
Answer : Option D
Explaination / Solution:
Tendulkar methodology defines poverty not in terms of annual income, but in terms of consumption or spending per individual over a certain period for a basket of essential goods.
Q2. A plant producing seeds but lacking flowers is
Answer : Option C
Explaination / Solution:
Gymnosperms produces seeds without formation of flowers. The gymnosperms (gymnos : naked, sperma : seeds) are plants in which the ovules are not enclosed by any ovary wall and remain exposed, both before and after fertilisation. The seeds that develop post-fertilisation, are not covered, i.e., are naked.
Q3. The plasma membrane consists mainly of
Answer : Option D
Explaination / Solution:
The plasma membrane is composed of lipids that are arranged in a bilayer. Also, the lipids are arranged within the membrane with the polar head towards the outer sides and the hydrophobic tails towards the inner part.
The membrane proteins can be classified as integral or peripheral. Peripheral proteins lie on the surface.
Q4. Which law is also called Principle of Stability of Mass Data
Answer : Option B
Explaination / Solution:
Statistical observations that any anomly can be discovered by comparing different samples if the samples from a large group of test population trend to group's charecterstics.
Q5. Deforestation leads to
Answer : Option B
Explaination / Solution:
No Explaination.
Q6. The strand of DNA that forms mRNA is called
Answer : Option D
Explaination / Solution:
During transcription, only one of the two DNA strands is copied. This is called the template strand because it acts as a template for the mRNA that is being assembled by the ribosomes. The sequence of the mRNA is complementary to the sequence of the template strand.
It is also known as sense strand.
Q7. A Wheatstone bridge ABCD is balanced with a galvanometer between the points B and D. At balance the resistance between the points B and D is :
Answer : Option D
Explaination / Solution:
No current passes through the Galvanometer in the bridge balance condition.
Therefore, the resistance between B and D is infinite.
Q8. What is constant in simple harmonic motion?
Answer : Option B
Explaination / Solution:
The time period of the SHM is given by where 'm' be the mass of the body (constant) , 'k' restoring force constant as T depends on 'm' and 'k' and they are constant for the system, so the corresponding Time period of the motion is Constant.
Q9. The calculation of masses or, (sometimes volumes also) of the reactants and the products involved in a chemical reaction is called
Answer : Option B
Explaination / Solution:
Stoichiometry is a method to express quantitative aspects of a chemical reaction .
Usually , the masses of reactants as well as those of products in a chemical reaction are calculated using corresponding balanced chemical equation .
It is convenient and hence desirable to calculate volumes of gaseous reactants and products .
Q10. presence of extensive hydrogen bonding between water molecules leads to
Answer : Option C
Explaination / Solution:
Water has high freezing point and boiling point because of strong intermolecular hydrogen bonding interactions.
