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.
Answer: When a plant is exposed to light, photons of appropriate wavelength will strike and be absorbed by the pigment-protein complexes arrayed on the thylakoid membranes. When this happens, the energy of the photon is transferred to the pigment molecule, thus causing the pigment to go into an electronically excited state. :)
Explanation:
Joshua saw the rising batter form the cake in the oven. What Joshua
observed was because of the<span> reaction of baking soda or baking
powder with the liquid in the batter: These ingredients react together
and cause air bubbles to form. Baking powder contains sodium hydrogen carbonate
that breaks down when heated, releasing carbon dioxide that helps cake mixtures
to rise during baking.</span>
<span>The answer is binary fission. This happens when during the replication of chromosomes of prokaryotes. Similar to mitosis, it divides itself and reproduces asexually. Many bacterias use this kind of process to produce more of this kind of organism inequal sizes. </span>
The Human Fish has the scientific name of Proteus. It has HUMAN-looking skin but otherwise there is no resemblance. Human and fishes share many developmental pathways, organ systems, and more which is why the human fish is called the human fish.
