1.) describe the amphibian life cycle. Include the different phases and traits of each phase.
Sedaia [141]

Answer:

1.) The Amphibian life cycle isn't as simple as it seems. The main Amphibian that has a longer process are called Frogs. Everyone knows frogs, but they are different from most animals such as turtles. The first stage of frogs are when their in eggs of course. These eggs are called "Tadpoles" and look different than most eggs. These eggs are kept in water until they grow. Which brings me to the next stage. When the tadpoles hatch you would start to see something like a baby fish swimming around. That's still the same tadpoles you saw before just hatched. When it comes to this topic most are confused because frogs don't have tails. Well during these stages a tail is used to help them survive in the water and move around. The third stage of these interesting creatures are when they grow legs. That's when they are able to walk on land. They still have their tail of course. It still helps them swim in water. I don't understand much about why they still have a tail if they've grown legs,  but that's for me to find out soon. Eventually they grow more and more and get better with their legs and lose the tail. Well the tail doesn't just magically disappear. It's actually absorbed  by using something called apoptosis. Then it's pretty much and adult frog.

2.) Most baby reptiles are grown in eggs. Another name for them would be "Amphibians". These little creatures are mostly kept in water or hidden underground for various reasons. Unlike turtles and lizards. Frog eggs are called "Tadpoles". They look like mini clear eyes. They also have a longer process than most animals which was explained in the first question!.

Hope this helped!
