How do specific cell structures and organelles contribute to maintaining homeostasis in the cell?

Homeostasis is a self-regulatory process by which cell maintains its internal environment constant. Plasma membrane plays significant role in in maintaining the homeostasis due to its semi-permeable nature. Cell membrane or plasma membrane is a phospholipid bilayer, it only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it. Thus it controls movement of molecules and maintaining the constant internal environment.  

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
