Answer:
Cell cycle checkpoints are checking for malformations in the cell that could be potentially dangerous later down the line.
Explanation:
Well our bodies are made from atoms which are also in supernovas. theoretically atoms make everything so that could be a connection. also, supernovas and bodies all have a time clock, or they were born at one point and will end up dying at one point.
Well assuming the original cell is a prokaryotic, you wouldn't be able to remove the nucleus because prokaryotic cells don't have a nucleus to begin with. if this doesn't help then: The cell would lack genetic information.
The snakehead could unreservedly eat little fish and scavangers, so that would evacuate/diminish the predator for zooplankton and phytoplankton. So zooplankton and phytoplankton populace would increment while little fish and scavanger populace would diminish. Presently if little fish and shellfish populace diminishes, their predators would have bring down sustenance, so vast fish pop. would diminish. On the off chance that vast fish pop. diminishes, their predators will have less nourishment thus the number of inhabitants in well evolved creatures will somewhat drop, however not by much, since they can feast upon zooplankton.
So at last, just the phytoplankton populace would increment while everything else diminishes.
