It is to do with the genes, but stem cells can differentiate into any kind of cell; the type they become depends on environmental influences. These come from neighbouring cells, which are producing chemicals that influence the stem cell differentiation. Signals are detected through receptor molecules on the cell surface, and the activated genes direct the formation of the kinds of proteins the cell needs to specialise.<span>

It seems that you have missed the necessary options for us to answer this question, so I just had to look for it. Anyway, here is the answer. POLYUNSATURATED <span>fats, such as olive oil and sesame oil, are produced in plants and are liquid at room temperature. Hope this helps.</span>
The RYR1 gene is responsible for producing the protein ryanodine receptor 1. This protein transport calcium ions to the cells for muscle contraction. When this receptor remains open for a long time, you would expect an excess of calcium ions which would result to muscle rigidity. The excess calcium ions would also increase body temperature and produce excess acid.
