Answer: The right answer is- Nucleus.

Nucleus is a membrane bound specialized organelle that is present in the eukaryotic cells ( such as plant and animal cell).

This structure possesses the genetic material (which is called DNA, deoxyribonucleic acid) of living organisms that is passed from one generation to the next generation. It contains the genetic instruction in the form of nucleotide sequences ( that are transcribed and translated to form desirable protein products). The proteins ultimately control all the functions of the cell.

Arte-miy333 [17]

The correct answer is by facilitated diffusion.  

The procedure of continuous passive transport of ions or molecules through a semi-permeable membrane with the help of particular transmembrane integral proteins is known as facilitated or passive-mediated transport or facilitated diffusion.  

It is a modification of osmosis incorporating a proteinaceous channel via which an extracellular solute can enter a cell in the absence of energy.

Arlecino [84]

<u>Answer</u>:       D. calcium chloride

<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>

<u>Explanation:</u>

<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>

It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>

They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
