Its yellow or orange head or large purple dorsal bar (in adult males) distinguishes this lizard from the similar Yellow-backed Spiny Lizard and Twin-spotted Spiny Lizard. Its lack of bars on the forelimbs distinguish it from Clark's Spiny Lizard. The similar Yarrow's Spiny Lizard has a complete collar.DISTRIBUTION: The Desert Spiny Lizard ranges across the deserts of southwestern Arizona and the northeastern plateaus at elevations ranging from near sea level along the Colorado River to about about 5,000'.t hibernates during the cold months of winter and late fall. DIET: The Desert Spiny Lizard feeds on a variety of insects including ants, beetles, and caterpillars. It also feeds on spiders, centipedes, small lizards, and some plant material.
Gravity pulls downward which supplies blood to the lower limbs. Microgravity pushes the blood to the upper portions of the body. The effects of microgravity isn't a big deal until astronauts travel back to Earth. Gravity pulls back the blood pressure down, but all the blood will transfer down to the astronauts' legs. This will cause other parts of the body to not have the blood they need to support the functioning of the astronauts' upper portion of their bodies.
The acoustic levitation chamber can be used to study the effects of microgravity. This gives researchers a place to study other than the International Space Station which is very difficult to get to. Current efforts in this research are directed toward fine control of the position and motion of the object.n object can be raised and even spun on any axis that is desired. This object is only in contact with the air molecules around it. In fact, the intensity of the sound is high enough that non-linear effects begin to be important in the description of the system.
