The Tasmanian devil is a marsupial mammal that lives only on the island of Tasmania off the coast of Australia Within the past 20 years, the Tasmanian devil population has been devastated by an infectious cancer that can be
passed from animal to animal. Scientists who have studied the Tasmanian devil believe this cancer may lead to
the extinction of the species. What factor regarding the population's gene pool justifies the scientists' prediction
of future extinction? Explain my

answer; the above statement is (true);

the tricuspid valve is present between right atrium and right ventricle

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
