We have all noticed the monthly variation in the moon's appearance: the cycle of phases, caused by the changing angle of the sun as the moon orbits the Earth. The moon cycle begins with the waxing or growing crescent,
visible in the west just after sunset. The first quarter moon is high in the sky at sunset and sets around midnight.
The full moon rises at sunset and is high in the sky at midnight and finally, the third quarter moon is often
surprisingly very visible in the daylit western sky long after sunrise.
We know we can see the moon in the sky at night but in the sky during the day? Determine which scientific model
represents the waning moon as the moon orbits Earth, as seen from the northern hemisphere.

this is a good question! i'll do some research and come back when i have the answer!

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.
