Answer:
going through Cytokenesis.
Explanation:
This is the process which climax cells division in plans and animals where the cells cytoplasm divides and two new daughter cells are formed. it occurs both in plants and animals but in different forms.
The point of initiation of cytokinesis is determined by the mitotic spindles and basically Cytokineses marked the beginning of new generation of cells.
it occurs in 4 stages which are initiation, contraction, stage of insertions of the membrane and completion of division. It is the contraction of the membrane and the eventual formation of the two daughter cells that resulted in fig -8- shaped under microscope.
<span>Enhanced Periglacial
Geomorphic processes resulting from seasonal thawing of snow in permafrost areas where the runoff refreezes in wedges, fissures, cracks and other structures. Periglacial areas can be enviroments where freezing and rethawing significantly restructure or modify the surrounding environment.</span>
Answer:
b. the new species must be unable to breed with the original species.
Explanation:
By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.
These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:
- Habitat isolation: Two species occupy entirely different and distant habitats.
- Temporal isolation: Two species procreate at different times of the year.
- Behavioral isolation: Two species exhibit different mating behaviors.
- Gametic isolation: The gametes of the two species cannot fertilize.
- Mechanical isolation
Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
The correct answer is: [B]: "behavioral" .
