Cell wall is an envelop covering the cell.Owing to its exceptional strength and its ability to control cell shape,the extracellular matrix of eubacteria,algae,fungi and plants is called the cell wall.cell wall provides rigidity and protection.It help in maintaining the shape and stiffness.
Answer:
Primary succession can be described as the development of a community in an area where there was no form of life before. For example, an area where volcanic eruption might have occurred.
Secondary succession can be described as an ecological succession which occurs in areas where the previous community had been destroyed by some kind of environmental disaster or human activity like fire etc.
As secondary succession occurs in areas where there was life before that means that the soil of this area will still have essential minerals and nutrients which will support life better as compared to areas of primary succession. In primary succession, the area might not even have soil. The rocks will be converted to soil in these area which will take a lot of time. Hence, an area that goes through secondary succession will likely reach its climax community before an area that goes through primary succession.
Answer:
The two populations might become separate species
Explanation:
Allopatric speciation is one of the mechanisms that can lead to the establishment of a new species of organisms as a result of geographical separation of different population of organisms of the same species.
<em>When organisms of the same species are geographically separated, this prevents gene flow between the two populations and each population develops various adaptive features in order to cope with their environments. Thus, each population might end up becoming a new species.</em>
