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.
Penguins are an iconic family of aquatic, flightless birds. Although we think of penguins as Antarctic birds some, like the Galapagos penguin, live in much warmer climates near the equator.ost notably their wings have become flippers, which are useless on land, but excellent in the water. Their striking black and white plumage is surprisingly effective at hiding them from the likes of killer whales and leopard seals. There are thought to be between 17 and 20 species of penguin.
