Answer:
1. import and export of nutrients and wastes
2. cell signaling
3. cell recognition
4. cell growth and motility
Explanation:
Plasma membranes are selectively permeable which means it only allows selective molecules to cross through it. So the plasma membrane helps in the import and export of nutrients by simple diffusion, facilitated diffusion or through active transport.
There are membrane protein embedded in the plasma membrane which have different role. Some help in cell signaling like GPCR, some help in cell recognition and some act and transporter proteins.
The plasma membrane is also responsible for cell growth and motility because it allow the raw materials and signals to pass through it which is required by the cell to metabolize and grow. So 1,2,3,4 is the correct answer.

The correct answers are "sometimes, no change or reduced".
If our sensory systems are exposed to the same exact stimulus repeatedly, sometimes it causes our sensory systems to react and sometimes it has no effect. In some cases, it may have a reduction of sensitivity, but sometimes it has no effect to our sensory systems.
