why do lizards bask on rocks in the early morning i need proper scientific answers please?

because they are cold blooded; research from there\n\nand use spell check!

Dinosaurs keep balance through the use of their tail. Additionally, think of it as how we ride a bike. The more speed, the easier it is to balance.

Most lizards are green, probably for camouflage.\n\nSince dinosaurs are lizard-like, they are expected to be green.\n\nHowever, dinosaurs are expected to be a variety of colors, green does not have much of an advantage. Lizards, though primarily green, can have a variety of colors or be able to change colors.\n\nAlso, it's easier to imagine a green dinosaur then a bright pink dinosaur. :D

Answer A) Small size & rocky surfaces

Birds have one, snakes have one, and i believe a few of the lizards only have one.

They have the short, simple digestive system of a carnivore that is very tolerant of rotting food full of bacteria.\n\nSome reptiles are also very tolerant of rotting food.

"they" don't because they don't really know.  when early paleontologists started reconstructing dinosaur fossils, there was not much known about forensic biology.  our understanding of the way bones fit together and the biomechanics of all those little bumps and ridges on the bones was not very complete, and so when the skeletons were reconstructed they ended looking more like lizards than birds, mostly due to the missing information being filled in by the early scientists' prejudices and assumptions.\n\na lot of the recent work on dinosaurs that asserts their bird-like characteristics (feathers, warm blooded, etc) are inferred from the bone structure and are pretty far-removed from the physical evidence.  the notion that dinosaurs are like birds is controversial because it's new, and all people (including scientists) take time to accept something that upsets the conventional wisdom.  it is good science and probably correct, but without any direct evidence it is pretty well impossible to know for sure.\n\nhowever some very-detailed fossils discovered recently in china appear to actually have feathers!  so this is pretty exciting and very good evidence for the notion of birdlike dinosaurs.  nevertheless people remain a) reluctant to change their views and b) uninformed about recent developments in paleontology.  most folks in the public are informed by books from their childhood and movies like 'jurassic park'.  the public takes a long time to come around to new discoveries in science, particularly when they challenge older models and when a field is changing rapidly.  it is also considered fairly irresponsible to present a controversial and barely-tested theory as "fact" by journalists and museum curators.  when the controversy in the scientific community settles down and a consensus is reached, then public education in museums and articles can begin and popular belief will change.

This theory sounds like a bunch of balogna (pronounced baloney). The reason that there is day and night is that a giant dragon eats the sun at night. And in the morning, it lays a new sun.\nBut seriously, day and night occur because the earth spins on its east-west axis. On some other planet (Neptune, I think) the sun rises and sets on its north-south axis.

I think all vertebrates use the same system we do.\n\nbugs have sensory hairs at all their joints. Especially the joints to head and to abdomen tend to be most important for gravity/balance perception (most mass attached). \nIn flying insects the ocelli (three single lens eyes on the top of their head) are thought to help with flight stabilization. Also flying insects have halteres to help with flight stabilization\n\nJellyfish, mussels and other marine invertebrates have statoliths/statocysts. Statoliths are made of a particular dense material and their displacement during acceleration/deceleration can be measured. \n\nI don't think bacteria care, but then they are not animals

The tail of lizards is an important element for locomotion and balance. These animals move by mean of undulations of their entire body axis (vertebral column), and the motions of the tail counteract those of the trunk.\nIn addition, most lizards are capable of autotomy, that is, they can shed their tail at need, usually when threatened by a predator or in other highly stressful conditions, and then grow a new tail. \nThis is achieved by means of special intravertebral fracture planes, that is, each of the autotomic vertebrae has a weak transversal plane through which it can break into two pieces. In addition, the tail muscles of the autotomic region are arranged in small "brick-like" packages that can become separated without much tissue damage; the blood vessels in the area also have the ability of closing and clotting rapidly so as to avoid excess blood loss.\nUnder stressful conditions, the animal will experience reflex contraction of those specialized muscles and a fragment of the tail will become separated from the rest of the body. This fragment continues to thrash and move for some minutes after autotomy, thus attracting the would-be predator while the lizard escapes to safety.\nAfterwards, a new tail will grow (this can take several months, according to the metabolic rate and general conditions of the individual); but this new tail does not have real vertebrae, only a rod-like support tissue. It usually has a blunt tip and different color/texture from the original tail. \nThere are _no_ autotomic vertebrae inside this new stump; therefore, the next autotomy will have to occur in vertebrae that are closer to the trunk. The number of these special vertebrae is limited, so the amount of autotomies is also limited. \nAutotomy is obviously advantageous as a means of escape. However, tail loss also implies a disadvantage, basically because: 1) as other users have answered, many lizards store fat supplies in the tail (although normally the basal part of the tail is not autotomic); 2)"growing back" a new tail requires more energetic resources that might have been used for other purposes; 3)until the new tail grows, locomotion may be somewhat impaired.\nAnd I'm leaving out other (e.g. social communication) uses of the tail.\nInterestingly, the tail won't grow back if the severance does not occur at the special fracture planes.

This type of reaction is caused by the nerves in the tail. The lizard Sheds its tail in an attempt to get away from predators. The movement in the tail is suppose to detract attention from the fleeing lizard.

Fossil bones and shells have turned into rocks.  That's why they're heavy.

I can show you a website that's a little technical, but should help.\n\nThe basic answer is, not really.  Most lizards are designed not to waste water, so they don't "pee" in the same sense a dog or a cat does.

The rain falls from lower altitudes where the ambient temperatures are warmer. The hail starts out as rain but high winds carry it upward to higher altitudes where it freezes due to lower temps. The hail stones fall and get wet as they pass through the warmer rain clouds, then they are swept up again to refreeze, thus growing larger in diameter. This process repeats until the hail stones get heavy enough that the upward winds cannot carry them up again. They fall to the ground. Large hail stones indicate high winds.

Reptiles dont have the ability to move jaws laterally, so they cant chew the way mammals can.

Hylonomus lyelli and Paleothyris are the oldest-known true egg-laying reptiles. Their fossils have been found in 310,000,000-year-old coal deposits in Joggins, Nova Scotia. They were about 8 inches long in adulthood and looked like modern lizards. \n\nI couldn't pick them out of a lizard lineup, personally.
