Mitosis simply refers to cell division in which one cell divides and produce two new cells that are identical.

Here are the steps:
(1) Prophase
<span>(a) Early prophase when cells starts to break down some structures and build others up. It sets up the stage when the chromosome is dividing.</span><span>(b) Prometaphase, mitotic spindle begins to capture and organize the chromosomes.
</span>
(2) Metaphase
<span>The spindle has captured all the chromosomes. They lined them up at the middle of the cell making it ready for division.
</span>
(3) Anaphase
<span>The sister chromatids separate from each other and are pulled towards opposite ends of the cell.
</span>
(4) Telophase
<span>The cell is nearly finished dividing, and it starts to re-establish normal internal structures as cytokinesis takes place.</span>

Match each component of biodiversity to the example of how it contributes to ecosystem stability.
professor190 [17]

Answer:  

Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.

Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.  

Species diversity:  Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.  

Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.

Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.

Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.

Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.

What drives the process of plate tectonics, the currently accepted explanation for the movement of drifting continents?
Elena-2011 [213]
<span>There is heat from the Earth’s core. Unfortunately, even thought the Earth is round, this heat isn’t evenly distributed. Therefore, sometimes the pressure from the heat in some areas can create currents that move the plates across the Earth’s surface.</span>
