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 :)

The main problem that your central nervous system will try to solve is how to get out of this place.

<h3>B. What is the somatic nervous system probably doing?</h3>

It is releasing stimuli so that the pupil dilates and the blood goes to the muscles, to give greater physical vigor.

<h3>ç. Which part of the autonomic nervous system is likely to be active and what is it doing?</h3>

The autonomic nervous system is a part of the nervous system that functions independently of will and consists of neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to the glands, smooth muscle and heart muscle.

<h3>What are the physiological responses of adrenaline binding in the sympathetic autonomic system?</h3>

Adrenaline increases the overall activity of the heart, increasing both the heart rate and the force of contraction. The heart has β1 receptors in both contractile and specialized myocardium. When turning on, a series of cardiac effects can happen.

With this information, we can conclude that the main problem that your central nervous system will try to solve is how to get out of this place.
