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.

In order to predict how much tension a muscle can produce when contracting, it is important to consider the ______ relationship
serg [7]

The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.

<h3>What is muscle contraction?</h3>

It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.

<h3>Characteristics of muscle contraction</h3>

  • In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.

  • The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.

  • To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.

Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.
