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.
There are 17 recognized species of penguins living today, although some subspecies are still in debate. They group in six different sets. Great Penguins. (2 living species) This group includes the Emperor Penguin and the King Penguin. As their name implies, they are the largest penguins, reaching a height up to 1.2 meters. Brush-tailed Penguins. (3 living species) This group includes the Adelie Penguin, the Chinstrap Penguin, and the Gentoo Penguin. Little Penguins. ( 1 living species) The little penguinâs collection is made up by the little blue penguin and the Northern little penguin. The Northern little penguin or white-flippered penguin as also known is one of the subspecies still in debate.
