Answer : Option D
Explaination / Solution:
Meiosis cell division consists of two phases. First phase is called meiosis I during which number of chromosome reduce to half the number in parent cells. In meiosis II chromosome number remain same.
Q2. In which condition gene ratio remains constant in a species?
Answer : Option A
Explaination / Solution:
Gene ratio remains constant in species having random mating. Gene flow, mutation and sexual selection are the factors that change the gene ratio of the population.
Q3. Larger animals like birds and mammals are usually stuffed and preserved in
Answer : Option D
Explaination / Solution:
Larger animals like birds and mammals are usually stuffed and preserved in museum. Hence, the correct choice is Museum.
Q4. Birth control measure should be
Answer : Option D

Q5. Production of a human protein in bacteria by genetic engineering is possible because
Answer : Option C

Human protein can be produced in bacteria by genetic engineering because genetic code is universal i.e. same codon in different organism’s code for same amino acids.
Q6. Identify the false statement out of the following
Answer : Option C
Explaination / Solution:

Q7. Which one represents regulative function of forests
Answer : Option B
Explaination / Solution:
The regulative function of forest is storage and release of gases. Plants in forests converts carbon dioxide gas into oxygen during photosynthesis.
Q8. The stage connecting meiosis I and meiosis II is
Answer : Option B
Explaination / Solution:
Interkinesis is the stage connecting meiosis I and meiosis II cell division. It is a brief period between two stages. No DNA synthesis occurs during this period. The cellundergoes preparation for next divisional stages.
Q9. Two geographical regions, separated by high mountain ranges are
Answer : Option C
Explaination / Solution:
The geographical region Palarctic and Oriental are separated by high mountain ranges. The geographical separation do not allow the gene flow as mating is not possible between member of species.
Q10. The famous botanical garden, Kew is located at
Answer : Option D
Explaination / Solution:
