Hydrolysis of ATP

Explanation:

The biochemical basis of rigor mortis in terms of the interaction between actin and myosin can be explained as the condition in which the muscle becomes arrested as ATP is unable to get hydrolyzed and this is basically the energy source that is needed for movement. Myosin head molecules becomes glued to actin filaments and the muscles become rigid in the absence of ATP. This condition peaks at 13 hours and then dissipates after 48 hours.

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.
