<prompt> Hlalosa mohopolo oa rigor mortis.nan  <response>: Instruction in English: Explain the concept of rigor mortis. . Response in English: Rigor mortis refers to the stiffening of the muscles of a deceased organism, resulting in the body becoming rigid, a few hours after death. This is a natural process that occurs due to the chemical changes that happen within the muscles of the body. Immediately following the death of an organism all bodily functions stops, causing a halt in the production of ATP adenosine triphosphate, which is the energy required for muscle movement including relaxation. As a result calcium releases and causes muscle to contract and since there is no ATP there is no energy to undo the effect. The stiffness of rigor mortis starts with the smaller muscles of the body such as those of the jaw and face, and then spreads throughout the body. The process generally begins about 2-6 hours after death and can last for approximately 24 to 48 hours. After this time, the process of decomposition begins to gradually loosen the muscles and the body returns to a flaccid state. . Response in Sesotho: Rigor mortis e bolela ho satalla ha mesifa ea sebōpuoa se shoeleng, e leng ho fellang ka hore mele o be thata, lihora tse seng kae ka mora lefu. Ena ke tsebetso ea tlhaho e hlahang ka lebaka la liphetoho tsa likhemikhale tse etsahalang ka hara mesifa ea mele. Hang ka mora lefu la ntho e phelang, mesebetsi eohle ea mele ea emisa, e bakang ho emisa tlhahiso ea ATP adenosine triphosphate, e leng matla a hlokahalang bakeng sa ho sisinyeha ha mesifa ho kenyeletsa ho phomola. Ka lebaka leo khalsiamo e ntša me e etsa hore mesifa e fokotsehe me kaha ha ho na ATP ha ho na matla a ho etsolla phello. Ho satalla ha rigor mortis ho qala ka mesifa e menyenyane ea mele e kang ea mohlahare le ea sefahleho, ebe e hasana hohle meleng. Tsebetso hangata e qala lihora tse 2-6 kamora lefu mme e ka nka lihora tse ka bang 24 ho isa ho tse 48. Ka mora nako ena, mokhoa oa ho bola o qala ho theola mesifa butle-butle me mele o khutlela boemong bo fokolang.
