Final answer:
Enveloped viruses, like influenza and HIV, are sensitive to changes in temperature, pH, and some disinfectants due to the fragility of their lipid envelope. Non-enveloped viruses are more resistant to these changes.
Step-by-step explanation:
Enveloped viruses, such as the influenza virus and HIV, are sensitive to changes in temperature, pH, and some disinfectants due to the fragility of their lipid bilayer envelopes.
The envelope of an enveloped virus is made up of a phospholipid bilayer and is studded with proteins.
In contrast, non-enveloped viruses are more resistant to these changes.
