1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.

2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.

3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches

4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

I tried my best hope this helps :)

<h2>Function of The Cell Membrane</h2>

Explanation:

  • <em>There are a few unique kinds of this simple development of particles. It could be as basic as atoms moving uninhibitedly, for example, assimilation or dispersion.  </em>
  • Proteins are utilized to help move atoms all the more rapidly. It is a <em>procedure called encouraged dispersion.</em>
  • It could be as straightforward as acquiring a glucose particle. Since the cell film won't permit glucose to cross by dispersion.  
  • The cells are in a zone where there is a huge focus contrast. For instance, oxygen particle focuses could be exceptionally high outside of the cell and extremely low inside.
  • <em>Those oxygen particles are little to such an extent that they can cross the lipid bilayer and enter the cell.  </em>
  • <em>This is a water explicit procedure. For the most part, cells are in a domain where there is one convergence of particles outside and one inside.</em>
  • Since focuses like to be the equivalent, the cell can siphon particles in an out to remain alive. <em>Assimilation is the development of water over the layer</em>
