Mitochondrial diseases result from failures of the mitochondria, specialized compartments present in every cell of the body except red blood cells. Mitochondria are responsible for creating more than 90% of the energy needed by the body to sustain life and support growth.When they fail, less and less energy is generated within the cell. Cell injury and even cell death follow.itochondrial DNA encodes just 37 of these genes; the remaining genes are encoded in the cell nucleus and the resultant proteins are transported to the mitochondria. Only about 3% of the genes necessary to make a mitochondrion (100 of the 3000) are allocated for making ATP.
No. Penguins are birds and birds are not mammals. They are animals of course, but mammals in general do not lay eggs, they nurse their young, and they have fur, not feathers. The duck-billed platypus, which seems to be stuck somewhere in middle, lays eggs, but has fur and does nurse its young.
The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica.The male and female are similar in plumage and size, reaching 122 cm (48 in) in height and weighing from 22 to 45 kg (49 to 99 lb).he emperor penguin breeds in the coldest environment of any bird species; air temperatures may reach â40 Â°C (â40 Â°F), and wind speeds may reach 144 km/h (89 mph). Water temperature is a frigid â1.8 Â°C (28.8 Â°F), which is much lower than the emperor penguin's average body temperature of 39 Â°C (102 Â°F).
