The correct options are as follows"
1.B.
Postzygotic isolation is a type of reproductive isolation which keeps species from mating with each other as a result of the differences that developed between them when they are separated by physical boundary. In the question given above, the lizard specie has been separated by the formation of a stream which divide the region into two.
2.B.
Allopatric speciation refers to the mode of speciation that occur when biological population of the same specie become isolated from each other to an extent that it interferes with genetic interchange. It usually occur as a result of change in the environment.
The reaction shown in the question is an inversion reaction.
The conversion of maltose to glucose is an inversion reaction. An inversion reaction is said to have occurred when the atoms and groups in a molecule are rearranged. The numbers and type of each atom in a molecule remains the same.
The reaction; Maltose +A -> Glucose + B is an example of an inversion reaction. The missing items A and B are both the catalyst maltase.

Answer:
D
Explanation:
Since Adenine (A) pairs with Uracil (U) in RNA, Thymine(T) pairs with Adenine but Adenine doesn't pair with Thymine in RNA and Guanine(G) and Cytosine(C) then the nitrogenous pairs would be like this.
