Passive membranes are unprotected because they do not have any specialized structures or mechanisms to actively defend against external threats. Unlike active membranes, which have proteins and pumps that can regulate what enters and exits the cell, passive membranes rely solely on the physical properties of the lipid bilayer to control the movement of molecules. This lack of active defense mechanisms makes passive membranes more vulnerable to damage from factors such as toxins, pathogens, and environmental stressors. **

PC hard drives are not inherently unprotected, but their level of protection depends on the security measures implemented by the user or the organization.

Additionally, installing security software and keeping it updated can help protect against malware and other cyber threats. However, if these measures are not in place, PC hard drives can be vulnerable to unauthorized access and data breaches. **
