Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature.
They are all tetrapoda.
Tetrapods are animals (group of vertebrates) with four limbs including amphibians (frogs), reptiles (caimans), birds (parrots) and mammals (hares, humans). Even though the subgroups within Tetrapods differ a lot, they all have various adaptations of the skeleton and muscles that enable them movement on land, adaptations of cranium (for head stability), tissues that reduce water loss (because of living outside the water)…Except amphibians all other tetrapoda are amniotes (have amnion layer around embryo)
Cells that do a similar activity join together to shape body tissue, for example, muscle, skin, or bone tissue. Gatherings of various kinds of cells make up the organs in your body, for example, your heart, liver, or lungs. Every organ has own must do, however all organs cooperate to keep up your body.
Heredity is the passing of physical characteristics unto the next generation a mouse for example might have brown fur the mouse he "gets busy with" also has brown fur likely hood of the baby having brown fur is a high likley hood hence you can say that the baby mouse has brown fur because of the heredity of his parents<span />
