Q1. Velocity of plane electromagnetic waves in vacuum equals
Answer : Option B
Explaination / Solution:
No Explaination.


Q2. Lymph will transport :
Answer : Option C
Explaination / Solution:

Fats are absorbed through lymph in the lacteals present in the intestinal villi.

Q3. in the same medium transverse and longitudinal waves
Answer : Option A
Explaination / Solution:

As speed of transverse & longitudinal waves depend on different modulus of elasticity (Young's modulus, Bulk modulus, Modulus of Rigidity) of the medium. So in the same medium transverse and longitudinal waves travel with different speeds

Q4. The best method to determine the homozygous and heterozygous of an individual is
Answer : Option A
Explaination / Solution:

Homozygous and heterozygous of an individual is determined by test cross method in which homozygous recessive is crossed with F1 hybrid individual.

Q5. How many net ATP are produced in Glycolysis?
Answer : Option B
Explaination / Solution:

At the end of glycolysis pathway, 2 net ATP molecules at step 6 and step 9 are produced.

Q6. Divalent magnesium and calcium ions are found in large proportions in biological fluids.
Answer : Option B
Explaination / Solution:

and  maintains the ion balance.

Q7. Vinegar is obtained from molasses with the help of
Answer : Option C
Explaination / Solution:

Vinegar is chemically diluted acetic acid which is produced by fermentation of molasses in presence of yeast and Acetobactor.

Q8. If the polarity of induced emf is such that it tends to produce a current which aids the change in magnetic flux that produced it, which conservation law is violated?
Answer : Option C
Explaination / Solution:

In this case we would be obtaining electrical energy continuously without doing any work.

Q9. Hyperconjugation in an organic compound is a
Answer : Option A
Explaination / Solution:

Hyperconjugation in an organic compound is a stabilizing interaction

Q10. In various experiments on photo electricity dealing with the stopping potential dependence on frequency of incident radiation , the conclusion was that stopping potential
Answer : Option A
Explaination / Solution:

The stopping potential is defined as the potential necessary to stop any electron even the electron with the most kinetic energy from reaching the other plate. Kinetic energy of electron depends on frequency not on intensity of incident radiation.
