Answer:
Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.
Explanation:
Answer:
We can't examin the specimen in tbe absence of lght. We can not study the internal structures.
Explanation:
The taxon was first named _Hyla microcephala_ by Boulenger
Answer:
e. Because gene flow between populations prevents genetic divergence in sympatry.
Explanation:
Speciation requires genetic divergence between populations of a species to isolate them reproductively. however, when present in the same habitat, gene flow between populations of a species does not allow their reproductive isolation and thereby, prevents the formation of new species. These populations need strong episodes of disruptive selection for their reproductive isolation.
On the other hand, two geographically isolated populations can not interbreed and thus, there is no gene flow between them leading to their genetic divergence and speciation. So, allopatric speciation is more common than sympatric one.
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
