Dapsone, also known as diaminodiphenyl sulfone (DDS), is an antibiotic commonly used in combination with rifampicin and clofazimine for the treatment of leprosy. It is a second-line medication for the treatment and prevention of pneumocystis pneumonia and for the prevention of toxoplasmosis in those who have poor immune function.
Unlike sexual reproduction, which requires genetic material from two parent organisms in order to create an offspring, asexual reproduction occurs when a single organism reproduces without the genetic input of another. Because of this, a single individual organism is able to produce a nearly exact copy of itself.
Most organisms use Light energy from the sun as their primary source of energy (through photosynthesis of plants) and a minority use and rely on chemical reactions to produce their energy (through chemosynthetic organisms).lants in turn rely on photosynthesis to create energy for their own growth and maintenance. Some bacteria can create energy from inorganic matter and some organisms feed on these bacteria. Therefore not all organisms depend on the sun as its primary source of energy, but most do.
