Q1. A human male produces sperms with the genotypes AB ,Ab , aB , ab pertaining to two diallelic characters in equal proportions. What is the corresponding genotype of this person?
Answer : Option A
Explaination / Solution:
The genotype AaBb of a male produce gametes AB,Ab, aB and ab in equal proportion as the law of segregation.
Q2. Ramesh has Rh antigen and Anti-A as well as Anti-B antibodies in his blood. During blood transfusion he can receive blood from :
Answer : Option D
Explaination / Solution:
Since he has both antibodies A and Band has Rh antigen and hence has O+ blood group. So, he can receive blood from O-positive blood group.
Q3. Which one is incorrect about Glycolysis?
Answer : Option A
Explaination / Solution:
Glycolysis is not a cyclic pathway and carbon dioxide gas is not released during this cycle. Oxygen is not required for Glycolysis process. Glycolysis occurs in cytoplasm of the cell.
Q4. For , bond order is
Answer : Option C
Explaination / Solution:
Bond order is the number of chemical bonds between a pair of atoms. in diatomic nitrogen N≡N, Triple covalent bond is present in nitrogen so the bond order is 3;
Q5. Biogas is produced by
Answer : Option A
Explaination / Solution:
Biogas is mixture of gases like methane, hydrogen and oxygen. It is produced by anaerobic breakdown of biomass like animal dung, animal wastes etc. It is used as fuel in rural areas.
Q6. A rectangular conductor PQRS in which the conductor PQ is free to move is kept in a magnetic field B ,which is perpendicular to the PQRS which lies in a single plane. If the conductor PQ of length l is pushed by a force F and circuit has resistance r,the power loss in the resistance is
Answer : Option B
Explaination / Solution:
Q7. Correct IUPAC name the following compound is
Answer : Option D
Explaination / Solution:
3,4- dimethylhexane will be correct iupac name as 6 membered carbon chain will be the main chain.
Q8. Each photon has the same speed but different
Answer : Option C
Explaination / Solution:
Each photon travels with the speed of light. Energy of photon is hν.
ν is the frequency of photon. Energy depends on frequency.
Q9. Which of the following is a wrong matched pair
Answer : Option B
Explaination / Solution:
Dystrophic lake have too low accumulation of dissolved nutrients to support abundant plant life so, they have very low productivity.
Q10. Molecular mass of a compound is the ------------- of atomic masses of elements present in a molecule .
Answer : Option B
Explaination / Solution:
Molecular mass is the sum of atomic masses of the elements present in a molecule.
For example ; Molecular mass of CO2 = atomic mass of one carbon atom & atomic mass of two oxygen atoms
=[ 12+2(16) ] u
= 44u.
