Biology Unit 4 Assessment 2020-2021 Question: 1-13
According to the fossil record, giraffes didn't always have long necks. Through time, they evolved to have long necks. What would be the best explanation for the longer necks? 15.13
O Certain traits can be favorably selected through time in a population if members of that population continuously breed with partners with the desired trait; thus, naturally selecting our those without the trait
The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks
O Divergent evolution explains why giraffes have long necks
O Convergent evolution explains why giraffes have long necks

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.

it's false. hope i .
