For the animal you choose, briefly describe it (physical description, habitat, then, list all the organ systems of the animal. from this list, choose one organ system to describe in detail. describe how the whole system works and functions. include the function of every organ involved in that organ system. use at least 500 words for your answer.

The Axolotl, or the Ambystoma mexicanum, is located in the class amphibia and in the family of Ambystomatidae. They are a critically endangered species that resides in Mexico. More specifically, the walking fish is native only to  Lake Xochimilco and Lake Chalco in central Mexico. These unique fish have many attributes that makes it different from other amphibians and fish found in lakes.

Axolotls are 9 inch "walking fish" that have the amazing ability to regenerate limbs. They can regenerate any lost limb, including their head. This salamander has a soft bodies with small "horns" sprouting from the sides of their head. These horns are actually gills, meaning that instead of having their gills located inside of their pharynx the frills are set on the sides of their head.  

The spots commonly found on an axolotl are not unusual, it's part of an extremely advanced system called the lateral line system. This system consists of electroreceptive ampullary organs and mechanoreceptive neuromasts organized into lines across the creature's body. This system is connected to the nervous system, and it allows the axolotl to sense movement and vibrations in the water.

This can get you started, I didn't want to make it too easy on you! :) It has I believe 126 words, I hope you find it useful!

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
