HELP!!! Considering the origins and processes involved in how natural gas, petroleum, and coal formed, which of the following is the best explanation regarding
why these resources are referred to as fossil fuels?
Natural gas, petroleum, and coal were formed by breaking open rocks that contain fossils from millions of years ago.
Natural gas, petroleum, and coal were only formed during the Jurassic period when dinosaurs walked the Earth.
Natural gas, petroleum, and coal were formed when organic matter that has been buried deep in the Earth was subjected to heat and pressure
over millions of years.
Natural gas, petroleum, and coal were formed when elements came together to form planet Earth billions of years ago.

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.

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
