The cell wall of gram-negative bacteria is thin (approximately only 10 nanometers in thickness), and is typically comprised of only two to five layers of peptidoglycan, depending on the growth stage. In gram-positive bacteria, the cell wall is much thicker (20 to 40 nanometers thick).
because different scientists have different theories or explainatons on how the universe came into being so that's why the origin of the universe is still a question
hope this helps
Answer:
partially permeable
Explanation:
A dilute solution contains a high concentration of water molecules, while a concentrated solution contains a low concentration of water molecules.

<h3>IVF: Is the process painful?</h3>
