<span><em>Whether living or non living:</em>
<em>When you put a sample of tissue under a microscope, if u can see a cell membrane, and can identify some cell structures like nucleus, mitochondria, vacuoles etc. , it was living, if not, its a non living thing.</em></span>
<span><em>However some cells don't have a nucleus( eg. prokaryotic cells), but all cells have a cell membrane or some sort of protective covering to contain the cell's insides. </em></span>
<span><em>To check if your specimen maybe-once living, maybe-still living "something", is living, get a look at it through an electron microscope - thats the best microscope ever- and see if the mitochondria's making any ATP( adenosine triphosphate, source of energy for most organisms), if it does, its living. If not, no</em></span><em>n living. :)</em>
It would b B.physically because solution is a mixture and mixture is formed by physical change not by chemical

Proteins perform numerous functions in the cell membrane, one of which is to regulate the movement of materials, atoms of elements and other ions as they are entering and exiting the cell. These proteins that play this significant role, would be classified as transmembrane proteins, which are specific kind of intergral proteins.
