What do you mean by mucous membrane?

Xena eventually catches Callisto (remember, she is 25 years old). Salmoneus, who is 60 years old, agrees to deliver Callisto to face charges for war crimes. On the way, their cart crashes down a ravine.  Salmoneus dies. When a cell dies its plasma membrane becomes “leaky”; i.e., it becomes permeable to ions that were unable to freely cross the membrane during life. Thus, after death, calcium ions leak across the sarcolemma of muscle fibers. This calcium leak causes rigor mortis, a temporary stiffness of the muscles after death. Apply your understanding of the mechanism of skeletal muscle contraction (specifically regarding events within muscle fibre) and explain the molecular basis of the phenomenon known as rigor mortis.

Can you please answer all of the parts of this question

WHat do the terms "freely permeable" or "impermeable mean with respect to the cell membrane? What would happen to the cell in either case?

Simple and facilitated diffusion differ because _____________. simple diffusion requires the presence of a transport protein within the plasma membrane, while facilitated diffusion does not ions being transported by simple diffusion move against their electrochemical gradients, while ions being transported by facilitated diffusion move along their electrochemical gradients 3.facilitated diffusion requires the presence of a transport protein within the plasma membrane, while simple diffusion does not 4. ions being transported by simple diffusion move along their electrochemical gradients, while ions being transported by facilitated diffusion move against their electrochemical gradients
