What characteristics do birds have that make them different from reptiles?
Birds are warm-blooded and have a high metabolic rate, walk with their legs directly beneath the body, and have a soft covering of feathers, rather than scales, over most of the body. By contrast reptiles are cold blooded with a low metabolic rate and walk with their legs out to the side (apart from snakes and legless lizards). In all, these traits of birds are actually more like those of mammals even though birds, as descendants of dinosaurs, are more closely related to modern reptiles.
Why do reptiles need to eat less than mammals?
Reptiles are cold-blooded, so their metabolic rate can drop right down which means that they use less energy which in turn means they don't need to eat that much.
Why do boys have a greater metabolic rate than girls?
yes
What adaptations enable birds to live in environments that are colder than those typically supporting reptiles?
Unlike reptiles, birds are endothermic. They also have feathers, which conserve heat.
When is resting metabolic rate higher than resting metabolic rate?
wait that would be the same question just asked twice. the answer would be never because it is resting
Does sleeping decrease metabolic rate?

The most similar thing about birds and reptiles is that they both lay eggs. However, it is important to note that not all reptiles lay eggs. There are many species of snakes and lizards which do not lay eggs, but instead give birth to live young.
What is the significance of a negative metabolic rate?
The significance of a negative metabolic rate is that it will eventually lead to death. As the body consumes more calories than it produces from its metabolism, it quickly breaks down.
Are animals related to birds?
Birds are more closely related to reptiles than they are to mammals. Birds, reptiles, and mammals all belong to a group of vertebrates called amniotes, which split off from amphibians. Amniotes split into two groups soon after they evolved: true reptiles and synapsids. Mammals are the only living synapsids today. Dinosaurs branched off from the reptiles and birds then evolved from the dinosaurs.
Is a utahraptor a reptile?
