- Evolution, Growth, and Genetic Code
- Metabolism
- Stimulus
- The wood frog is an extraordinary amphibian possessing the ability to withstand 3-degree temperatures because it adapted to make its own anti-freeze. It has a genetic code to make the right proteins in order to grow. Its life begins as an egg and it grows into a tadpole. It then grows back legs, then the front, then it becomes an adult frog.
- Cells
- The wood frog needs to eat 2-3 insects a day when not frozen. It metabolizes the insects to gain nutrients and breaks them down for energy.
- Homeostasis
- The wood frog senses that winter has come and he starts to get ready for his hibernation. He produces lots of urine for anti-freeze and mixes it into his blood. The water in his blood reacts to the cold by freezing. For the frog to survive it needs to produce glucose to mix with the urine to make the anti-freeze.
- Reproduction
- With the anti-freeze, the water gets melted and goes back into the cells. This is so the frog does not die from dehydration.
- The frog always has to maintain its required temperature for its internal organs to function properly. It also has to keep a steady supply of water and other things to survive.
- In breeding season a female can produce up to 3000 eggs which hatch between 9 and 30 days after. These eggs later turn into tadpoles and then frogs.
