Hello! My name is Gus., I'm a wood frog and I have the ability freeze and stay alive!
I have the ability to do this because when my parents had me they passed don their genetics down to me.
Growth And Evolution
I've grown from a small egg to an adult frog. With growing I started to use this ability to survive freezing tempatures I have from evolution in my species
Stimulus
When it's starts to get cold my brain sends a signal and my body's response is to start this process so I survive the cold.
Winter is coming and the wood frog is about to start the process of making its own anti-freeze.
Metabolism
This ability was gained from evolution to be able to survive the harsh winters the wood frog has to go through.
Cells and Homeostasis
Once the temperature reaches a certain point the frog sits in one spot to start the process.
After Winter.
The frogs liver starts to produce more glucose and infuses its urine with its blood to make its own antifreeze
When this proccess starts my body infuses my urine and blood together to make an antifreeze. My body also makes my liver produce more glucose to start this process.
While the frog starts to freeze the water in its cells starts to be sucked out. The frog's body keeps the cell's water above 60% because if it goes below, the process will not be reversible.
My body starts to freeze and the water in my cells are beign sucked out so the antifreeze I made makes sure to keep 60% of the water in thm because if it goes below 60 the proccess is irrevisable.
Once winter is over the frog starts to defrost and the process is reversed. Then the frog begins to look for a mate.
After Winter I start to defrost and start to be more active. Once I'm completley unfrozen I go and look for a mate!
