Great Question! Mass is basically how heavy Something is. Most people confuse mass with weight but there very different from each other. Weight is the downward force something has because of gravity. Mass can be measured in a variety of units too. The second part of the question is how it affects density. It affects it because to find the density you need to be able to find the mass since the formula is Mass divided by volume. I hope this helped you understand a little bit more about mass. Have a great day!
is there a question selection?
The answer to your question is B. matrix
Answer: The correct answer is
No, because NaCl is Ionic
Explanation:
NaCl can pass through the cell membrane because it is Ionic and separates into Ionic components Na+ Cl+.
Cell membrane are phospholipids bilayers and have hydrophobic tails and face inside of the cells . The fatty acids tails are non polar and only non polar substances can pass through it but salts is a polar molecules because it is an ion and cannot pass.
I think it’s o+ if not try o- sorry if this was no help
