Earth was able to retain an atmosphere because of its gravity. It is <span>the same force that keeps us anchored to Earth. Molecules in our atmosphere are constantly moving, spurred on by energizing sunlight. If Earth were much less massive, gravity's grip would be weaker.</span>
Answer:
Hybridization may drive rare taxa to extinction through genetic swamping, where the rare form is replaced by hybrids, or by demographic swamping, where population growth rates are reduced due to the wasteful production of maladaptive hybrids. Conversely, hybridization may rescue the viability of small, inbred populations. Understanding the factors that contribute to destructive versus constructive outcomes of hybridization is key to managing conservation concerns. Here, we survey the literature for studies of hybridization and extinction to identify the ecological, evolutionary, and genetic factors that critically affect extinction risk through hybridization. We find that while extinction risk is highly situation dependent, genetic swamping is much more frequent than demographic swamping. In addition, human involvement is associated with increased risk and high reproductive isolation with reduced risk. Although climate change is predicted to increase the risk of hybridization‐induced extinction, we find little empirical support for this prediction. Similarly, theoretical and experimental studies imply that genetic rescue through hybridization may be equally or more probable than demographic swamping, but our literature survey failed to support this claim. We conclude that halting the introduction of hybridization‐prone exotics and restoring mature and diverse habitats that are resistant to hybrid establishment should be management priorities.
Explanation:
Answer: a deciduous forest
Explanation:
If you look at pictures of a deciduous forest progressing from fall to winter, you’ll see the dry leaves on the forest floor. Then, in winter images, you can see that the tree branches are bare.
Answer:
The theory of the formation of fossil fuels is that fossil fuels are the remnants of organisms that lived a long time ago and were buried, heated, and formed into hydrocarbons.
Explanation:
A is not correct because the nitrogen is not a gas that is dominant in fossil fuels.
B is not correct because the oxygen can not turn to carbon in any manner.
C is correct because the consensus about the formation of fossil fuels is that after the organisms were dying out, they were getting buried (usually in the soft layers of the ocean floor), over time with the higher temperatures and pressure from below managed to change their structure and create hydrocarbons.
D is not correct because there hasn't been any evidence so far that there are fossil fuels on comets and asteroids.
Either Hawai'i or Oregon, I live in Oregon and the forests seem very tropical, but the most likely answer is Hawai'i.
