True or false? homologous chromosomes are
the two identical chromosomes that make up
one of the 23 pairs in a mother cell.

False

Explanation:

During meiosis, 46 chromosomes pair up and cross over with another homologous pair resulting in 23 homologous chromosomes. However, the chromosomes in the homologous chromosomes pair are not identical which is what allows for crossing over to result in recombinant variation.

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.
