Duchenne's muscular dystrophy is a disease characterized by a progressive and severe muscle weakness. It affects the cardiac and respiratory muscles leading to death because of the failure of these muscles. Death usually occurs in early adulthood. The disease is inherited and is caused by mutations on the DMD gene.
Histological findings in this disease show whorled muscle fibres, increase in fatty replacement of muscles, increase in endomysial fibres, regeneration, necrosis and myofibre splitting.
There is an observable variation in the sizes of the myofibres, with large and hypertrophic fibres mixing with small and atrophied fibres. There's also an increased internal nuclei.
Homeostasis is the term used to describe a cell's relatively constant internal physical and chemical conditions. It also balances the acidity and alkalinity, (pH).

Explanation:
These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps:
Excitation of photosystems by light energy.

Reduction of NADP+ and the photolysis of water.
The windward side faces the prevailing, or trade, winds, whereas the island's leeward side faces away from the wind, sheltered from prevailing winds by hills and mountains. Here is only some characteristics.
