input: Please answer the following: - In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell - In prophase the chromosomes become visible and the centrioles separate and move to opposite poles of the cell - In metaphase the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere - In anaphase the sister chromatids separate into individual chromosomes and are pulled apart - During telophase the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes - Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear. What might be the first step of the process?
++++++++++
output: Prophase is the first and longest stage of mitosis

++++++++++
output: Dirty dishes are rinsed

input: Please answer the following: - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms - It will turn into either petroleum or natural gas - What might be the first step of the process?
++++++++++
output:
Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand
