Sun 101 - Which two complementary forces keep the Sun from blowing itself up?
labwork [276]

Fusion and gravity

Fusion and gravity keep the sun from blowing itself up.  A large amount of energy is released by the sun. Protons are fused together to form helium atoms due to the high heat and pressure at the center of the sun. The Sun does not blow itself up from the outer pressure of nuclear fusion in as much as the inner force of gravity balances it.

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.

kirill [66]
The survival of the species is ensured by C. by protecting the fertilized eggs from predators. The protection provided by the male increases the hatch rate of the eggs, which means more young seahorses. The greater the number of hatchlings, the greater the likelihood that some will survive  to adulthood and carry on the survival of the species.
