There has been many changes over time in species of frogs. Maybe back then, the frogs couldn´t freeze. With genetic code, the frog was able to get the traits and skills needed to help him survive in the ice.
Cells
The frog shown in the video was a fully grown adult. It started off as an egg. Then it became a tadpole that grew into an mature adult frog . That frog is able to survive on its own.
Metabolism
The frog knew winter was coming, so he began preparing for it. The frog went into a small space so he could try to stay warm or atleast not too cold.
Reproduction
When the frog starts freezing, the ice sucks the water out of the frogs cells. Then they use their urine for their cells.
When the frog finishes defrosting, one of the first things it does is going out and looking for some food to eat. It had not eaten in 8 months.
After the frog finishes defrosting, the first thing it does is look for some food and look for a mate.
