1. in the system shown below, there are 80 x particles, all in region a (the left half of the box). no extra particles can enter the system. when the system is in

equilibrium, what will be true of the particles?

a since there are no y particles, the system is already in equilibrium with ail 80 x particles in a

b. due to the constant motion of particles, this system will never reach equilibrium

c. in equilibrium, there will be exactly 40 x particles in a and 40 x particles in b, and those numbers will remain constant

din equilibrium, there will be approximately 40 x particles in a and 40 x particles in b, and those numbers will fluctuate but will remain near 40

the contamination

we are putting to many trash.

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.
