Q1. Flagellated, motile asexual reproductive structure are called
Answer : Option A
Explaination / Solution:
A number of simple organism produce single or multi-flagellated spores called zoospores. Water is essential for this mode of reproduction. Aplanospores are non-flagellated spores.
Q2. The basic laws of physics are universal means
Answer : Option C
Explaination / Solution:
Laws of nature as expressed in physics as laws and theories are often said to be universal. This means that, so far as we have been able to test them, they apply everywhere and at every time, past, present and future.
Q3. The boiling point of isomeric branched chain alkene is
Answer : Option C
Explaination / Solution:
As surface area decreases with branching,the boiling point also decreases.
Q4.
Arrange the following in decreasing order of their basic strength :
Answer : Option B
Explaination / Solution:
Alkyl amines and ammonia are more basic than aniline because in aniline lone pair on N is in resonace with benzene ring so is less available.
Also more 20 alkyl amines are more basic than primary amine and ammonia due to +I effect of the alkyl group which increases basicity.
Q5. Solubility of gas decreases with
Answer : Option C
Explaination / Solution:
Because of increase in kinetic energy of gas molecules with temperature there tendency to escape from the liquid will increase.
Q6. Agriculture education ,health and infrastructure were the priority areas in which five year plan.
Answer : Option A
Explaination / Solution:
Eleventh five year plan focussed on improving the quality of life through better health and sducational facilities and improved levels of consumption. It also focussed on reduction in inequality.
Q7. Direct tax is a tax whose
Answer : Option D
Explaination / Solution:
No Explaination.
Q8. Relationship between mode is
Answer : Option D
Explaination / Solution:
In a normal distribution in which the values of mean, median and mode coincide, (i.e. mean = median = mode) is known as asymmetrical distribution. Mode=3 Median-2 Mean
Q9. Unemployment is the result of
Answer : Option C
Explaination / Solution:
The major cause of unemployment and underemployment in underdeveloped countries like India is the deficiency of the stock of capital in relation to the needs of the growing labour force.
Q10. When bodies are in contact with each other then
Answer : Option A
Explaination / Solution:
according to newton's third law of motion for every action there is always equal and opposite reaction or the mutual actions of two bodies upon each other. Whenever two objects interact with each other, then the pair of forces acting on them are equal in magnitude and opposite in direction.
Contact forces are mutual forces (action and reaction)
