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:
The lava fluid and spread out over large area
Human health can be affected by changes in air quality mainly because if the air is bad they will have various health defects. For example with some of the cities in China much of the air there is polluted. Thus human health may be affected by added stress as well as breathing in polluted air which will cause side effects.
All in all human health is affected by changes in air quality because air is what humanity breaths to survive. If in some way this air were to be polluted we would suffer from decreased health due to a circulation of fossil fuels in our atmosphere.
B.
Energy can’t be created nor destroyed
The answer is b!
The answer is b because flowers are the lightest and are transported to produce more flowers.
