I think the correct answer would be the last option. Monozygotic twins are identical, while dizygotic twins are fraternal. Identical twins involves developing from one zygote where it splits, forming two embryos so that the twins would have more or less the same characteristics. This type of twins can share the same amniotic sac depending on the time the fertilized egg is divided. On the other hand, fraternal twins developed from two eggs wherein they are being fertilized by two different sperm cells resulting to twins which has different characteristics. For this type, the two fertilized eggs would develop separate amniotic sacs.

<h3><u>Answer</u>;</h3>
d. Na+ 
<h3><u>Explanation</u>;</h3>
- The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. 
- <em><u>Small molecules that are non-polar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.</u></em>
- Charged ions  such as N+ and K+ Cannot permeate the cell membrane for the since uncharged molecules repel uncharged molecules present in the membrane structure.
