Zelda is a marathon runner. She completes the marathon in 2 hours and 30 minutes. Which of the following is true regarding her fuel use during the marathon? A. If she runs out of muscle glycogen at the 2-hour mark, she will not feel fatigue.
B. Anaerobic glucose breakdown, using muscle glycogen, will provide most of the ATP for the marathon.
C. Liver glycogen is the preferred fuel during intense muscular activity lasting less than 2 hours.
D. As exercise duration increases beyond 20 to 30 minutes, blood glucose will become increasingly important to spare muscle glycogen, so Zelda will have the ability to sprint across the finish line.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

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.
